MMOPA will be hosting it’s second Safety Standdown event at many locations across the country for Piper PA46 owners and pilots. The first iteration of MMOPA Safety Standdown in the fall of 2019 was a big hit. Each event was very well attended by MMOPA members.
What is Safety Standdown you ask? Safety Standdown was put together as a mid-year training event as part of the MMOPA Master Aviator program. It’s goal is to allow PA46 owners and pilots to fly in to a location at a reasonable time (the event starts at 10am local time), received some good quality ground training over relevant safety topics by highly experienced PA46 instructors, have a free lunch, then depart mid-afternoon to arrive back home before dark.
The event is free to all attendees. Lunch will be provided at each location. This event is not exclusive to MMOPA members, either. Any PA46 owner or pilot, or just anyone interested in the PA46 world, are invited to attend.
Texas Top Aviation is hosting the South Central Region Spring Safety Standdown at the Henrickson Jet Center at the Austin Executive Airport (KEDC). Hank Gibson and Pedro Vargas-Lebron will be presenting on the following topics:
MMOPA Operational Practices review and importance of stabilized approaches
Crosswind Takeoffs and Landings
High Density Altitude Operations
A discussion of thunderstorms, resources in the cockpit for weather avoidance, and accidents that have occurred involving thunderstorms
The MMOPA Spring Safety Standdown will take place on Saturday, April 18th, 2020. Registration is required for the event. The link for registration can be found here.
Come on out for some high quality training and free BBQ with 50 of your closest PA46 buddies!
The Malibu and M-Class Owner’s and Pilot’s Association (MMOPA) announced new Safety Foundation Training videos in September. The videos are aimed at both new Piper PA46 pilots and existing Piper PA46 pilots, all in the effort to fly the Piper PA46 to the highest and safest standards.
Six videos have been released thus far, with the promise of more to come. The topics of the first videos are:
Instrument Approach
Visual Approach
Manual Gear Extension
Emergency Descent
Descent Planning
Takeoff and Climb
Eventually, the goal is to release high quality training videos encompassing all aspects of Piper PA46 flying.
To view the videos, you will need an MMOPA membership. The link to the MMOPA Safety and Education Foundation video page is: https://www.mmopasafety.org/education/
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.
From the time I started flying, I have always had the dream to learn how to fly a seaplane. As I learned in November, it’s actually learning to land a seaplane, and the veterans call them floatplanes.
ProMark Aviation at the Burnet Airport (KBMQ) offers a weekend float plane course that is high on fun and low on stress. The school has a Piper PA12 Super Cruiser on amphibious floats (amphibs as I was corrected at one point. I mean, if you’re going to fly a seaplane, er, floatplane, you have to know the lingo) that will land and takeoff on water, but does little else with ease and grace. At 150 HP with those big floats and all the associated rigging hanging underneath the airplane, you are lucky to get to 500 feet before you get to your destination.
We weren’t working on setting any speed records. I was learning the lay of the water. I learned about the step, the keel, pumping the floats, how to read the water, currents, ducks (yes, ducks and birds are important to know about when you are flying low on the water), buoys, docking, and ditching. Step taxiing was fun as you are basically at 3/4 throttle screaming across the top of the water just below flying speed. It’s the best way to taxi a seaplane (truly, it is. You get more air in your engine, you can see better, and you are moving. Just don’t try and turn sharp).
Floatplanes also don’t have any shock absorbers, so the higher the wave, the more you get knocked around, so wind velocity and, in turn, wave height is very important.
A very important nuance of an amphibious floatplane compared to a straight floatplane (one that doesn’t have wheels that come out of the floats), is at one point, you want to make sure your gear is down for landing (runway landing) and at another, you want to make absolutely sure your gear is up for landing (water landing). If you land wheels down in the water, you will capsize, 100% of the time. Thankfully from my good instruction, I did not capsize.
Ken Wittekiend, my instructor, and I spent the majority of the weekend landing and taking off on Lake Buchanan (I was informed by locals it is pronounced “Buk-cannon”, not “Bue-cannon”), which is more open and therefore has more waves. We did one landing on Inks Lake so my kids could see me land, which they thought was the best thing since cheese sticks.
There is a check ride at the end of the training, but, as Ken reassured me, it’s the most fun check ride you’ll ever have. I still hate check rides, but that one I think I hated least of all.
I hope someday I can put my floatplane skills to practice, but for now, I can vouch that I now speak seaplane!
The long anticipated certification of the Cirrus Vision Jet finally happened. On October 30th, the FAA awarded certification to Cirrus’ single engine jet. Marketed as the world’s first single engine personal jet, the Cirrus Vision Jet will seat five adults, two children, and cruise around 300 knots.
The Williams FJ33-5A Turbo Fan engine is operated by a FADEC, single handle throttle, similar to the throttle in the piston powered Cirrus family. In fact, the SR series was taken into consideration when designing the Cirrus Vision Jet in order to simplify the upgrade for pilots. Many of the buttons and knobs are in the same places in the Cirrus Vision Jet.
The Cirrus Vision Jet is equipped with the Cirrus Perspective Touch by Garmin that is very similar to the Cirrus Perspective by Garmin in the piston powered line. Equipped also with the Flight Into Known Icing system and the Cirrus Airframe Parachute System (CAPS), both of which are standard.
Unlike the piston powered Cirrus lines, the CAPS system on the Cirrus Vision Jet is actually mounted in the nose. Also, unlike the piston lines, the jet CAPS is integrated with the aircraft avionics to slow the airplane to between 67 and 160 knots when the system is activated. In the jet, the CAPS system was designed to withstand higher weights, higher speeds and higher altitudes.
Cirrus hopes to start deliveries of the Vision Jet by the end of the year, with many more rolling off the line in 2017. All Cirrus Vision Jet pilots will need to be type rated in order to fly the aircraft. Cirrus is doing all the type rating training in house at their new Vision Center in Knoxville, Tennessee.
For a long time, I was happy if an FBO had a radio where I could tune the ATIS or automated weather before getting into the plane. This would allow me to skip listening to the weather in the airplane with the engine running, giving me a quicker exit from the ramp while burning a little less fuel. I would also be able to brief my taxi route from the ramp since I would know which runway was in use before getting in the plane.
As we progress forward in technology, I’m constantly amazed at how much more planning I can do from the palm of my hand. Now, I can call a phone number and get the ATIS, AWOS, or ASOS, depending on the size of the airport; if you prefer reading a text version…well, there’s an app for that.
With this technology, it’s very important for pilots to be aware of what service they are utilizing when calling these numbers. Usually only a Class B or larger Class C airport will have a phone number specifically for ATIS as well as one for AWOS/ASOS. These are listed in the Airport/Facility Directory (AFD), as well as all flight planning apps (Foreflight, Garmin Pilot, Stratus Insight). More then one pilot has called the AWOS/ASOS number for an airport thinking they would receive the ATIS (because towered airports that have ATIS phone numbers often also have AWOS/ASOS phone numbers that are different). Since the pilot didn’t hear a code on the phone, that led to the false thinking that either the tower was closed or the pilot did not have the code (ie. Information Bravo) to give to ground control when calling for taxi instructions. The minute weather can be very useful for flight planning, but the ATIS must be received before contacting ATC at a towered airport.
Notice the red box just past halfway down the page. There is a phone number for the ASOS at KSAT and a separate phone number for the ATIS next to the frequency.
Sometimes, you may get a busy tone if someone else is on the line. Usually, waiting a few minutes and trying again will lead to success. Just like old school phone lines, only one call can go through at at time! If it’s a particularly stormy day, you may be fighting a number of pilots to get on the line. In this case, an app where you can read the ATIS may be particularly helpful (Yes, there actually is a dedicated ATIS App!).
The ATIS app allows us lowly pilots without an Aircraft Communicating and Reporting System (ACARS) to access the Digital ATIS (D-ATIS ) at airports where ATIS is available. Only 76 airports in the US have D-ATIS, most of which are either Class B or busier Class C airports. Foreflight also provides D-ATIS textually at the same 76 airports, though it is only accessible depending on which subscription level you have with Foreflight (since I’m not a Garmin Pilot or Stratus Insight user, I’m not sure if either of them give D-ATIS reports).
ATIS App Symbol
With Foreflight’s D-ATIS, it does not get updated over ADS-B, only when your iPad or phone have an internet signal. When inbound to an airport with D-ATIS, the pilot has to listen to the radio frequency to get the current ATIS. Foreflight will display the last D-ATIS it received, but typically, it’s old. Check the time in the upper right hand corner.
On the Airports page on Foreflight, tap Info, then tap Weather & Advisory and the phone numbers will display along with the ATIS frequency
On the Airports page, tab Weather, then tap D-ATIS, and the last received D-ATIS will display. Note the age of the D-ATIS in the upper right hand corner
Foreflight now offers Pre-Departure Clearance (PDC) at those same 76 airports. With either a pre-registered tail number or a Foreflight call sign (starting in FFL), once a pilot files an IFR flight plan, the D-ATIS and the IFR clearance in it’s entirety are texted to the phone number the pilot filed with. All that is left to do is call ground, state “I have information Romeo and my clearance, ready to taxi,” then away you go. Skipping listening to the ATIS and talking to Clearance Delivery saves a good 5-10 minutes at times, depending on how busy the airport is.
These days, there are many different avenues to get the current weather (and IFR clearances!). When calling on the phone, the key is to be aware, know which number you are calling and, if you are expecting to hear an ATIS message but instead hear the AWOS/ASOS, verify the Chart Supplement Guide and Notices to Airmen (NOTAMS) to check tower hours of operation before flying into the airspace.
Density Altitude: Pressure Altitude corrected for non-standard temperature.
That’s the book definition of density altitude. The problem is, that definition leaves a lot of general aviation pilots scratching their heads. What really is density altitude?
All airplane engines rely on air and fuel mixing together, then that mixture is ignited to create combustion. Normally aspirated piston engine airplanes get their best performance at sea level, where the air is nice and thick, allowing plenty of air molecules to get sucked in the engine intake. As a normally-aspirated airplane climbs, the ambient air pressure drops with an increase in altitude (the air gets thinner, less dense), thereby reducing airplane takeoff, climb, and landing performance. There just isn’t as much air at higher altitudes, to put it simply.
Turbo charged piston engines assist with this air density problem. A turbo charger boosts the air coming into the engine and fools the engine into thinking it is at sea level pressure all the time. The higher the altitude, the faster the turbo charger spins, spinning the compressor faster, which compresses more air to continue to give the engine sea level pressure air. This gets faster cruise speeds the higher you go.
Both normally aspirated & turbo charged engines do experience longer takeoff rolls and reduced climb rates at higher airport elevations & higher altitudes.
How does this all relate to density altitude?
When the outside air temperature rises, the air becomes thinner, less dense. This means that when an airport elevation is 1,000 feet, but the density altitude is reported as 3,000 feet, the airplane engine thinks it is at 3,000 feet. It won’t accelerate as fast. The airplane’s climb rate will also be reduced. That means that the normal climb pitch attitude a pilot is used to seeing won’t be accurate at higher density altitudes. It will lead to slower indicated airspeeds, slow enough to potentially lead to a stall if a pilot isn’t paying attention.
Where does this get dangerous? High elevation airports. Whenever the OAT creeps above 85 or 90 at an airport that is higher elevation (I would classify higher elevation as 2,500 feet or higher), the corresponding density altitude sky rockets. If a pilot isn’t paying attention to airspeed or angle of attack (if the airplane is equipped with an AOA), a stall can come very quickly on climb out.
What to take home from this? Monitor your climb speed and angle of attack, especially right after takeoff, when you hear density altitude on the ATIS or AWOS.
