Austin Executive Airport opened a control tower on Friday, February 23rd 2018. The airport is now officially Class D airspace. The charts and A/FD are not updated yet to reflect the tower, but there is a NOTAM with the tower and ground frequency information. The tower hours are from 6am to 10pm. The weather frequency remains the same.
Make sure you check those NOTAMs if you are headed to KEDC anytime soon!
Let’s say you’re flying in the mountains of Colorado on a cloudy day. There’s a solid layer from the surface all the way up to 14,000 feet. You’re inbound to Eagle (KEGE) on the RNAV (GPS) D approach. There are mountains next to you and below you, but you aren’t concerned since you can see them all. The base of the last reported overcast layer was 3,000 feet, so you know you’ll break out before the MDA and land no problem.
At 11,100 over AWACC, you clearly see the top of the mountain below you. You are comfortably above it. You already have the runway in sight as well. You pop out of the clouds on the approach at 9,700 feet, spot the airport and follow the tower’s instructions to circle north of the runway for a left base for runway 7.
How could you see the mountains inside the clouds? You have Synthetic Vision installed on your glass panel, that’s how.
Aspen Synthetic Vision
Synthetic Vision, which has actually been around since the ’70s when NASA and the US Military first developed it, was first FAA certified for the Gulfstream PlaneView flight deck in 2009. Garmin, Avidyne, and Aspen are the main general aviation manufacturers of synthetic vision these days. All Garmin PFDs are now equipped with Synthetic Vision while Aspen gives you the option to upgrade to Synthetic Vision when you get one of their PFDs installed. Avidyne gives you Synthetic Vision in their R9 upgrade for the Cirrus.
What is Synthetic Vision? Basically, it’s a 3-D picture on the primary flight display showing terrain, obstacles, traffic, and runways. It greatly enhances situation awareness in areas of terrain or high obstacles during IFR conditions or at night.
The goal behind the development of Synthetic Vision was to decrease the amount of controlled flight into terrain (CFIT) accidents. A CFIT accident consists of a perfectly airworthy airplane flown by a pilot (or autopilot) unintentionally into terrain. These accidents can happen in low visibility conditions or at night, but the reason is mainly due to the pilot losing track of his position in relation to obstacles or terrain (or water as was the case with JFK Jr.).
With Synthetic Vision, the goal is to enhance pilot knowledge of what is around the airplane at all times. When you’re at altitude, the terrain below you looks flat. When you start descending down amongst the rocks, the hills or mountains start to rise up on your screen. For those used to the coloration with the 2-D terrain feature on a GPS unit, it translates very easily to the terrain coloration on a Synthetic Vision equipped PFD. Terrain that is between 100 and 500 feet below the aircraft is shown as yellow, while terrain closer than 100 feet is depicted as red.
Garmin Synthetic Vision
One neat feature on Garmin units is the Highway in the Sky. When a pilot puts a course or a flight plan in the GPS, the PFD displays magenta boxes at the altitude selected displaying the route. It’s handy when hand flying to just “fly through the boxes.” They also display descent angles on approaches.
Synthetic Vision is still optional on Garmin and Aspen units, but I highly recommend springing for it. It will give you a higher level of safety and keep you out of the rocks.
If you have been searching “Cirrus SR22T for sale” or reading up on the Cirrus Vision Jet, you are looking at genuinely excellent airplanes. Both have earned their reputations. This is not an article about why you should not buy one. It is about a third airplane that almost never shows up in a Cirrus search — and what the numbers look like when you set it next to the two you are already considering.

What the Cirrus SR22T Gets Right
Let us start where we should. The SR22T is one of the most successful piston singles ever built, and for good reason. Turbo-normalized power that holds performance up high. A Perspective+ flight deck that is about as good as glass gets in a single. Side-yoke handling most pilots fall for inside ten minutes. And CAPS — the whole-airframe parachute that changed how our whole industry talks about safety.
Add strong resale, a deep service network, and one of the best owner communities in aviation, and you have an airplane that is very hard to argue with. If you fly two people and light bags on 300 to 500 nautical mile legs, we would tell you to go buy one — and we would help you find the right one. We also teach Cirrus SR20, SR22 and SR22T training here in Texas, so this is not an outsider’s opinion of the airplane.
The conversation changes when the mission grows.
Cirrus SR22T vs. Diamond DA62: The Numbers Side by Side
The Diamond DA62 is a seven-seat, twin-engine, Jet-A-burning composite airplane that most Cirrus shoppers have never sat in — usually because it simply never came up in the search. Here is how the two line up on the numbers that matter.

Cirrus SR22T figures are taken from the Cirrus SR22T G6 Pilot’s Operating Handbook (P/N 13772-007, Reissue A): cruise at ISA and 3,400 lb, takeoff and landing over a 50-ft obstacle at sea level, ISA and 3,600 lb max gross.
Read that speed line carefully, because it is closer than the marketing on either side suggests. At 10,000 feet the DA62 has about six knots on the SR22T — real, but hardly decisive. Climb higher and the advantage flips outright: the SR22T is turbo-normalized, so at 18,000 feet the POH shows 198 KTAS on the same 18.3 gallons an hour, comfortably faster than the DA62. If raw speed is what you are buying, the Cirrus has a genuine answer.
Where the DA62 separates itself is everything around the speed. It burns Jet-A, which runs roughly $1.75 a gallon under 100LL at most FBOs and is available at airports where AvGas gets harder to find every year. And the full-fuel payload gap is 187 pounds. Payload is where light-airplane trip plans quietly fall apart.
Four Adults, Bags, and the Range That Actually Matters
Spec sheets get written for two people. Real trips are not flown that way.
Load four adults and 75 pounds of luggage — call it 835 pounds — and the SR22T has to leave fuel on the ramp. On a typical G6 empty weight that leaves room for roughly 48 of its 92 usable gallons, and realistic range lands around 320 to 350 nautical miles with IFR reserves. Put that same 835 pounds into a DA62 and you are looking at roughly 648 nautical miles with a 45-minute reserve.
To be fair to the airplane: with full fuel and two people aboard, the SR22T is genuinely long-legged. The POH shows 763 nm at 10,000 feet and 791 nm at 18,000 feet on a 45-minute reserve. The range only collapses when you fill the seats — which is precisely the mission this comparison is about.
That is not a rounding error. That is one fuel stop versus none on a Texas-to-Colorado weekend. And the DA62 does it across three rows, with two seats still open behind you.
About the Cirrus Vision Jet G1
If your search has moved from the SR22T up to the Vision Jet, that airplane deserves real credit too. Cirrus did something nobody else managed: a single-pilot personal jet, with CAPS, delivered in volume, flown successfully by owner-operators. That is a genuine achievement in this industry, and we teach Cirrus Vision Jet training ourselves.
The G1 specifically, though, asks for a level of commitment that surprises a lot of first-time jet buyers.
Cirrus Vision Jet G1: What Ownership Actually Asks Of You
Acquisition: approximately $1.8 million.
Fuel burn: 60–70 GPH of Jet-A.
Full-fuel payload: only 300–400 lb — roughly two adults and a soft bag.
Range: about 800 nm on paper, but heavily payload-limited in practice.
Type rating: a full FAA type rating is required — roughly two weeks of initial training in Knoxville, Tennessee.
Insurance dual: 25+ hours of additional dual instruction beyond the type rating.
Recurrent: annual simulator recurrent training back in Knoxville, at $15,000–$25,000 per year, every year.
Runway: 3,192 ft takeoff / 3,011 ft landing over a 50-ft obstacle.
Climb: drops to 1,100–1,200 fpm at heavier weights, and loses thrust at high density altitude airports — exactly where you want margin.
Worth saying plainly: the G2 and G2+ are meaningfully more capable airplanes — better payload, better hot-and-high performance, updated flight deck. That is a different and more interesting conversation, and one we are glad to have. Everything above is specific to the G1, because the G1 is the airplane most often cross-shopped at DA62 money.
Compare that training path to the DA62. A multi-engine rating is all that is required — roughly one week, typically at your home airport, with no hotel and no travel. There is no annual sim requirement in another state, and no recurring five-figure training line item on the budget.
Runway Numbers Open Up the Map
Performance over a 50-foot obstacle is where your airport list gets long or short. The DA62 clears it in about 1,575 feet on takeoff and 1,447 feet on landing. The SR22T needs 2,080 and 2,535 feet. The Vision Jet G1 needs 3,192 and 3,011 feet.
That is roughly 500 feet less than the SR22T on departure and nearly 1,100 feet less on arrival — and against the G1 the gap is wider still. Practically, that difference is what gets you into the shorter ranch, lake and mountain-adjacent strips that a lot of the best flying runs on. That is not a spec. That is a different set of weekends.
The Parachute and the Second Engine
CAPS is a real safety system and we will not say otherwise. It has saved lives, and it deserves the respect it gets. It also carries a cost most buyers do not budget for: the rocket and canopy repack runs about $20,000 every ten years, and it is not optional.
The DA62 answers the same question a different way. Lose an engine and you still have one making power, turning counter-rotating props, managed by a FADEC that keeps it to a single lever per side. One number to know either way: the DA62 single-engine service ceiling is 11,000 feet, so on one engine it will hold altitude over most terrain but not over the high country. Neither answer is wrong — they are two philosophies about the same risk. The DA62 version just does not come with a recurring five-figure bill.
Frequently Asked Questions
Is the Diamond DA62 faster than a Cirrus SR22T?
Only down low, and only slightly. At 10,000 feet the Diamond DA62 cruises at 190 KTAS at 90% power on 19 GPH of Jet-A total, while the Cirrus SR22T G6 POH shows 184 KTAS at 85% power on 18.3 GPH of 100LL. Higher up the SR22T is the faster airplane — its turbo-normalized engine holds 198 KTAS at 18,000 feet on the same fuel flow. The DA62 advantage is fuel cost, payload and runway, not raw speed.
How much can a Diamond DA62 carry compared to a Cirrus SR22T?
The DA62 carries a 762 lb full-fuel payload across seven seats in three rows. The Cirrus SR22T has a useful load of about 1,125 lb and a full-fuel payload of roughly 575 lb. Loaded with four adults and 75 lb of bags — 835 lb total — the DA62 flies about 648 nm with a 45-minute reserve, while the SR22T is closer to 350 nm.
What training does a Cirrus Vision Jet G1 require compared to a Diamond DA62?
The Vision Jet G1 requires a full FAA type rating: about two weeks of initial training in Knoxville, Tennessee, plus 25+ hours of additional dual for insurance, plus annual simulator recurrent back in Knoxville that runs $15,000–$25,000 per year on an ongoing basis. The Diamond DA62 requires only a multi-engine rating — about one week, usually at your home airport, with no travel.
Can a Diamond DA62 use shorter runways than a Cirrus SR22T or Vision Jet?
Yes. Over a 50-foot obstacle the DA62 takes off in about 1,575 ft and lands in about 1,447 ft. The Cirrus SR22T needs about 2,080 ft and 2,535 ft, and the Cirrus Vision Jet G1 needs about 3,192 ft and 3,011 ft. The Vision Jet G1 also sees climb rate fall to 1,100–1,200 fpm at heavier weights and loses thrust at higher density altitude airports.
Does the Diamond DA62 have a whole-airframe parachute like Cirrus CAPS?
No. The DA62 redundancy is a second engine rather than a parachute. One practical difference in ownership cost: the Cirrus CAPS repack runs about $20,000 every ten years and is mandatory, while the DA62 has no equivalent recurring safety-system expense.
Talk about star treatment. The Lajitas Golf Resort rolled out the red carpet for the 2019 Texas Top Aviation Lajitas Fly In. I had been to Lajitas twice before; once in July when it was hot, miserable and bumpy. The second time was the week before our Fly In. Both times, everyone from the airport folks to the bus drivers to the front desk and restaurant staff were top notch. It made for a very pleasurable experience.
If you haven’t been out to Lajitas (or don’t even know where it is) and you’re a pilot (you don’t even have to play golf), you have missed a sure gem. Lajitas is positioned on the southern tip of the Big Bend area of Texas, right on the Rio Grande river. Lajitas has great lodging with several different room options from big to small, an excellent restaurant for 3 square a day (and even a bakery for sweets, coffee, and breakfast tacos in the mornings), and a 5 star golf course in Black Jack Crossing.
Why is this all relevant to us aviators? Lajitas has it’s own private airport, 89TE. Complete with a 5,500 foot asphalt runway, VFR conditions most of the year, and reasonable fuel prices, Lajitas is the pilot’s gateway to the resort and the entire Big Bend area. If you wait until the fall, a brand new, 7,000 foot concrete runway should be completed and an IFR approach should be available. An AWOS is in the works too.
The resort and airport are so far south, radar and radio coverage with Albuquerque Center is pretty poor below about 15,000 feet, and non-existent below 10,000 feet. This isn’t a big concern as any airplanes in the area should be on 122.9 and the airport manager will make contact with you, give you a weather report, and assign a runway.
Once you are on the ground, there will be a resort bus waiting to whisk you and all your friends to the resort for your getaway.
The 2019 Texas Top Aviation Lajitas Fly In was a big hit. We had 7 airplanes total: 5 Cirrus SR22s, 1 Piper Matrix, and 1 Citation M2. There were 15 attendees total, including 13 golfers. Everyone raved about the resort and the golf course. The only hiccup in the weekend was the cold front that blasted through on Friday afternoon, kicking up a lot of dust. Golfing on Saturday was windy too, but Sunday morning was absolutely perfect.
Thanks again to the folks at Lajitas for the star treatment!

Just south of the equator in the mountains of Papua, Indonesia on the island of New Guinea, pilots spend their days carrying food, building supplies, doctors, pigs, and passengers into some of the most remote and extreme airstrips on the planet. That’s where I fly.
Each morning I load my Cessna Grand Caravan with 2,600 lbs of (insert strange cargo here) and depart my home base of Wamena just after the sun sends its first rays of light across the waking skies above. I spend my day winding through narrow valleys and crossing high altitude mountain passes with building clouds and poor communication, only to land on short, narrow airstrips with steep slopes and little room for error. Most of these one-way in, one-way out runways require me to commit to landing well before touchdown due to terrain that is too close to allow for a safe go-around. Everything better be right when I cross that decision point or I could be in for some excitement.
The need to keep wide margins of safety might seem obvious in environments like mine, but that doesn’t make them any less important where you fly. You may be a new pilot or an old timer, but keeping your margin should always be on the top of your priority list.
Let’s unpack this further. Margin is not just maintaining the regulatory requirements for cloud clearances or minimum altitudes. It’s more than planning for an alternate airport or carrying the required fuel reserve. Margin is breathing room. It is that extra maneuvering room, the Plan C, the well thought out options that provide you multiple “outs” in any given situation. Margin is what gets you home when things take a turn for the worse.
Margin comes in all shapes and sizes. For myself it includes maintaining double my required turn radius in narrow valleys or choosing not to land when my groundspeed is just 1 knot too high at a short and slippery airstrip. For you, it could be determining a ceiling or visibility minimum requirement that is more conservative than the legal ones or setting a wind limitation that you know is reasonable. When it comes down to it, keeping your margin means you don’t push to the ragged edge of your skill or the aircraft’s capability.
Margin can also refer to your mental or emotional capacity. Are you mentally prepared to divert and miss that important event because the weather is getting bad? Are you ready to handle the disappointment of passengers when you arrive over your airstrip and choose not to land due to approaching rain or a factor that is difficult for a non-pilot to understand? Are you willing to cancel a flight on an important client because you are coming down with a cold or didn’t get adequate sleep? As the PIC of your flying machine, you alone are responsible for the safety of the aircraft and the people on board and those are the tough calls that only you can make.
Fatigue, overconfidence, and complacency are the biggest obstacles to keeping your margin. They are all very subtle dangers and you may be experiencing them without even recognizing it. Fatigue can slow down your thought process leaving you behind the plane and backed into a corner before you know it. Overconfidence might cause you to push weather or commit to a course of action that has no favorable alternatives. Complacency will lead you to believe that, because you have 2000 hours in a particular make and model, you don’t need to do a thorough preflight or complete the pre-landing checklist.
Regardless of experience level, operating environment, fancy avionics, and level of proficiency, margin is something that we all need plenty of. So as you go about your upcoming flights, be asking yourself what you can do to build in more margin. It just might be what gets you home.
Pete Greenwald is a transplant to Atlanta, Georgia who has fallen in love with all things Southern, including his wife, Ashley. As a pilot and A&P with Mission Aviation Fellowship, he flies the Cessna Grand Caravan in Papua, Indonesia serving people who live in isolation. In his spare time he is on the hunt for the best burger around.
Are you one of those pilots who hates fuel stops simply for the fact that the engine doesn’t have time to cool off? You pump gas into the plane, hit the bathroom, get in the plane and the oil temperature is still up at 160-170 degrees, leading you to have to figure out how to get the plane going again with a hot engine. For those without proper training, this usually means a lot of jockeying around with the throttle, mixture, and fuel pump to try and get the thing started without flooding it. After coughing and wheezing several times, the engine finally comes to life, leaving you to only guess what worked and without the knowledge of how to duplicate it.
Let’s take a step back for a minute to see what is actually happening with a hot engine. Once the engine is shut off, the fuel in the lines leading from the tank to the engine is vaporized, meaning there is more air in the fuel lines than liquid fuel. In the engine block itself, there is still liquid fuel in the injectors, but only enough for the engine to cough then quit if started.
When a normal priming and starting procedure is performed, too much fuel is forced into the cylinders and the engine becomes flooded. A flooded engine just means that the stoichiometric ratio is way too rich, meaning there is too much fuel and not enough air. The prime does the trick of getting the fuel vapor out of the fuel lines, but it shoves too much fuel into the cylinders. Once the engine is flooded, it’s a waiting game to allow air into the engine to get the mixture right. All Lycoming powered high performance and turbo charged engines are notoriously easy to flood when hot.
So, what’s the solution? By taking a step back to see what is actually happening, you can attack the problem from the source, which is the fuel lines. You need to get the vapor out of the fuel lines and get some liquid fuel in there. The procedure for this varies based on the make and model of engine, but I’m going to use the example of the Continental IO-550-N that is in a Cirrus SR22. I found this procedure in the Continental Engine Manual and it works every time.
(Pilots of other airplanes, keep reading. I have sections below for PA46s, Columbias, and Bonanzas as well )
Mixture: Full Lean (this allows fuel in the fuel lines, but prevents it from going past the mixture control into the engine, sending all fuel back to the fuel tank; a small amount of fuel leaks past the mixture control providing prime for the engine)
Throttle: Idle
Low Boost Pump: Run for 30-60 seconds (see note below) (15 seconds in the Turbo Cirrus)
Mixture: Full Rich
Throttle: Open about 1/4 travel (not 1/4″, that won’t be enough)
Boost Pump: Off, but have your finger on Low Boost
Starter: Crank (engine will turn over a few more times before firing, this is normal)
At the first indication of start, turn the Low Boost on, increase the throttle to ensure the engine catches, then adjust the throttle for 1,000 RPM
The engine will fire right about the time you start thinking it isn’t going to work
A few notes regarding engine temperatures:
If the oil temperature is above 150 degrees, a hot start will be required. If oil temp is close to 200 degrees, run low boost for 60 seconds in a non-turbo. If oil temp is 175, run low boost for 45 seconds in a non-turbo. If oil temp is 150, run low boost for 30 seconds in a non-turbo. Use 15 seconds for all temps above 150 in a Cirrus Turbo.
If the oil temperature is between 125-150, skip the hot start procedure, don’t prime the engine, leave the boost pump off, and crank the engine, then boost pump on when it starts and slightly increase throttle to make sure the engine catches
If the oil temperature is between 100-125, skip the hot start, don’t prime the engine, and perform a normal start with the boost pump on
If the oil temperature is below 100, perform a normal prime and start
Piper Malibu (PA46-310P with Continental Engine)
Mixture: Full Lean (this allows fuel in the fuel lines, but prevents it from going past the mixture control into the engine, sending all fuel back to the fuel tank; a small amount of fuel leaks past the mixture control providing prime for the engine)
Throttle: Idle
Low Boost Pump: Run for 15-30 seconds depending on oil temperature…
Greater than 150 degrees: 30 seconds
Less than 125-150 degrees: 15 seconds
Less than 100-125 degrees, no need to run the Low Boost
Perform normal cold start below 100 degrees
Mixture: Full Rich
Throttle: Open about 1/4 travel (not 1/4″, that won’t be enough)
Boost Pump: Off, but have your finger on the Primer Button
Magnetos: On
Starter: Crank (engine will turn over a few more times before firing, this is normal)
Engine should fire with the Low Boost Pump off, but…
If the engine starts to die, simultaneously increase the throttle a little bit and hit the primer button.
Only tap the primer button, don’t hold it as you’ll flood the engine if you hold it At the first indication of start, turn the Low Boost on, increase the throttle to ensure the engine catches, then adjust the throttle for 1,000 RPM
Piper Mirage & Matrix (PA46-350P and PA46-350T with Lycoming Engine)
Leave throttle and mixture idle
Before you turn the battery on, ensure the mixture is idle cutoff
If the mixture is forward and the battery is on, the low boost pump in the fuel tank will start pumping fuel to the engine and quickly flood it
Ensure Magneto switches are on
Open throttle 1/4 travel (not 1/4″ as this won’t be enough)
Crank
As soon as the engine begins coughing and wheezing (and this is what it will sound like), push the mixture 3/4 of the way forward
Once the engine has a good solid fire, smoothly and swiftly push the mixture all the way forward
Reduce throttle
Note: The Emergency Boost Pump can be used as part of the hot start technique, but I usually leave it off.
Pro to the Emergency Boost Pump is it can help suck more fuel in and purge vapor during the start
Con is that if the engine doesn’t start on the first try, you are flooding your motor
Columbia 400
Throttle and Mixture Idle Cutoff
Vapor Suppression: Run for 30-60 seconds. Reference above temperatures on the non-turbo Cirrus for run times
Mixture full forward
Throttle 1″ in
Prime for 3 seconds, then off
Crank
Once engine fires, primer might need to be pushed momentarily to purge excess vapor
On Columbia 350s, the throttle should be twisted (or pushed depending on if it’s an Avidyne or Garmin Columbia) in while cranking
Be prepared to reduce power once engine fires
Beechcraft 36 Bonanza
Throttle and Mixture Idle Cutoff
Low Boost: Run for 30-60 seconds. Reference above temperatures on the non-turbo Cirrus for run times
Mixture full forward
Throttle open 1″
High Boost until fuel flow peaks, then off
Crank
Once engine fires, Low Boost might need to be engaged momentarily to purge excess vapor
There are other “procedures” for hot starting out there, but most of them involve starting with full throttle, which can lead to the airplane shooting ahead on a ramp or taxi way if the brakes aren’t properly set. This can lead to high repair costs, so always be cautious. Figuring out what is happening when the engine is hot will give you a better chance of getting it started right away.
As pilots, we are all familiar with the IM SAFE acronym that the FAA puts out. It comes up as part of the ground training over Human Factors during private pilot ground school. We all memorize it, spit it out for our check rides, then most of us promptly forget about it.
When I was training for my pilot’s licenses, I was at a Part 141 school that was very standardized (LeTourneau University, who has a fabulous aviation school). Before each flight, we had to do a self evaluation based on the weather and the IM SAFE checklist. Based on our answers, we would then determine if the conditions were conducive to flying as well as if I was physically okay to fly.
This was a great tool because not only do pilots have to pre-flight the airplane, they also need to pre-flight themselves. It’s very easy to fall into one of the “Hazardous Attitudes” if there is a pressing meeting or you haven’t flown in a while and it’s a beautiful day, but maybe you aren’t physically fit to control an airplane.
Let’s break down the IM SAFE checklist to dig a little deeper into the physically fit side of flying.
Illness
This one is pretty easy. Are you sick? If so, how sick? If you can’t hardly talk or your body feels like it was hit by a truck, then flying probably isn’t in your best interest.
The tricky area can become if you are only a little sick. Maybe you have a cough or a little cold or a headache is starting to form. You probably could go fly, but is it really a good idea? It could be something worse, or it may be nothing. You have to know yourself and put limits on yourself before you wake up on the day of your big meeting two states over. Set illness personal minimums and stick to them.
Medication
There are a slew of drugs, both prescription and over the counter, that pilots cannot take and fly. AOPA has a hotline to call for pilots to find out if they can fly with the medication they are taking, or what meds they can take to give them relief and still operate an aircraft.
Another great resource is your medical examiner. Just give him/her a call and they will be more than happy to let you know what you can and can’t take. They’ve been educated in the area of aviation so they are very knowledgeable.
Stress
This is a huge one that pilots ignore a lot. Maybe it was a stressful day at work, maybe you are running late to the airport, your meeting got moved up, whatever. Stress can jump on you and mess up a pilot’s thinking very quickly. If you have a lot of other things on your mind and you aren’t able to focus just on flying, it might be a good idea to stay on the ground.
Alcohol
Out of the whole IM SAFE list, the alcohol limitations are very clearly defined. 8 hours bottle to throttle, no more than 0.04% BAC, no operating an airplane while under the influence, and no carrying passengers who are visibly intoxicated. For your personal minimums, it’s a good idea to increase that time to 12, 18 or even 24 hours bottle to throttle.
Fatigue
Learning to fly while a college student led to a fair share of canceled flights due to fatigue. I operate best on 8 hours of sleep in the past 24 hours. I can function on 6, but anything less than 6 hours, my performance drastically drops off, sometimes to a point where I wouldn’t be safe. I discovered this while with my flight instructor attempting to do a holding pattern and completely botching it up.
I observed this as a CFI quite often. If I was doing ground with a student and they were struggling, my first question would be, how much sleep did you get last night? More often than not, if I had to ask that question, I would get an average answer of 3 to 4 hours (I even had one guy show up for a flight block on 2 hours sleep. I sent him back to the dorm).
Fatigue is very easily overlooked because it’s not measurable. Needing to get a flight lesson done or needing to get somewhere when you are obviously fatigued is not a good idea. Make sure you get a good night’s sleep before a flight and don’t be afraid to cancel if you didn’t. Set some sleep personal minimums and make them hard and fast.
Eating
Don’t skip meals and fly. Performance greatly decreases when a pilot is hungry. At the very least, stick a couple of food bars in your flight bag to give you some nourishment.
Also, stay hydrated, especially in the summer time. I carry a huge bottle of water with me on all my flights because I get headaches if I don’t drink enough. Getting dehydrated on a long flight can lead to all sorts of performance problems (over hydration is also a problem in the air, but that’s what Gatorade bottles are for, right?).
All this to say, have some personal minimums when it comes to you and your body. Check the plane, check the weather and check yourself. If anything falls in the “red” area in any one of those three categories, stay on the ground and don’t press your luck.
This is a huge one that pilots ignore a lot. Maybe it was a stressful day at work, maybe you are running late to the airport, your meeting got moved up, whatever. Stress can jump on you and mess up a pilot’s thinking very quickly. If you have a lot of other things on your mind and you aren’t able to focus just on flying, it might be a good idea to stay on the ground.
