Beware of the Lunch Monster

He prowls around, preying on innocent pilots.

He’s very sneaky, creeping unexpectedly and attacking after the propeller begins to turn.

He’s very cunning, veiling his intentions until, BOOM, he attacks.

Beware of the Lunch Monster!

Whenever I am doing a full day of training (which is usually how transition training courses are planned out, in full day sessions), I always plan a lunch stop.  My metabolism has the speed of a rocket ship, so I get hungry and need some sustenance in the middle of the day.  I have a running list of airports to stop at that have good lunch spots at them or nearby, so my customers and I usually end up at one of those airports.

Almost without fail, if a customer is having an excellent flying morning, nailing all the procedures, picking up all the techniques, and overall, flying pretty well, then eats lunch, the afternoon doesn’t go quite as well.  Doing some of the same things we did that morning, but the customer’s performance isn’t quite as good.  Most of the time, it’s just a brain lockup or landings aren’t quite as squeaky as they were in the morning.

Part of it is fatigue after flying for 2-3 hours in the morning.  The other part is what I call the Lunch Monster.  Eating a big lunch can sap away brain power and cause a person to lose energy around 2-3pm, leading to an afternoon lull (or the Lunch Monster attacking!).

According to Forbes.com:

Diet contributes to energy levels too. “Eating a lunch that is too big is the most common reason for feeling sleepy in the afternoon,” says Rebecca Solomon a nutritionist at Mount Sinai Hospital in Manhattan. “All your energy goes into digesting the enormous meal.”

The goal is to keep the body’s Cortical and Cortisone levels even since they’re the hormones released by the body in reaction to stress–they produce the fight or flight response. Their levels are elevated when you have sugar, caffeine and processed food, so you feel awake and energetic. But a few hours later, when those levels drop, you’re sluggish.

Solomon recommends eating a meal that’s balanced with healthy fats (from olive oil or avocados, for instance) with protein and healthy carbohydrates (whole wheat bread or pasta). The portion will vary for people of different sizes, but a general rule is you should be hungry about four hours after the meal.

Another healthy eating habit: Consume small portions of foods throughout the day, including almonds, carrots and hummus and fruit. Enjoy lunch around 1:30 or 2 p.m., just before the time you normally feel fatigued.

Now, most of the stops on my list of restaurants don’t fit the bill of healthy fats and healthy carbohydrates (plenty of protein, though, especially the BBQ joints).  For those days, bringing along a snack like almonds or dried fruit is a great idea to munch on mid-afternoon.  Trimming down the amount eaten at lunch helps a lot too.

So, the next time you have a long day of flying or training, beware the lunch monster and prep some good snacks when your flight instructor says you’re stopping for BBQ!

  • Selecting the Proper Altitude

    One of the first questions a student pilot asks me when starting the cross country portion of his or her training is, how do I know what altitude is best for my flight?  This is a good question, because without taking certain aspects of the flight into account, it’s really just a crap shoot when selecting an altitude.  Craps and flying don’t mix, so let’s take a look at a few considerations when selecting an altitude.

    Sky Coverage

    Sky coverage has several subcategories when it comes to selecting an altitude.  First is how high are the bases?  Is it IFR (VFR pilots would be grounded), marginal VFR (1,000 AGL to 3,000 AGL ceiling), or good VFR (above 3,000 AGL ceiling)?  If the cloud deck is only 2,500 feet off the ground, then VFR pilots are limited to either 1,000 AGL to 2,000 AGL.  This is an excellent segue into why VFR pilots shouldn’t scud run!

    Scattered Clouds

    Second, what kind of cloud deck is it?  Is it an actual ceiling (broken or overcast), or is it a scattered layer?  Few or scattered layers usually allow VFR pilots to find a hole to get higher to some smoother air, making the flight more pleasant.  VFR pilots, always make sure to check the destination weather as it could be scattered where you are departing from, but it might be broken or overcast where you are arriving.

    Last, how high are the tops of the clouds?  Pilots can only get this information in the planning stage from the area forecast or from pilot reports, so most of the time, it’s not very precise information.  If the tops are at 10,000 feet and the pilot is flying a 172 on a 30 mile trip, it doesn’t make much sense to get on top of the clouds.

    Terrain and Obstacles

    Terrain goes hand in hand with sky coverage.  If there are low clouds and high terrain, that doesn’t bode well for trying to stay VFR and not hitting anything.  Obstacles need to be taken into account too, as there are some pretty tall radio towers that can stretch up into a 1,500-2,000 AGL deck of clouds.

    Winds Aloft

    Winds Aloft

    Once the sky coverage and terrain have been considered, it’s time to look at the winds aloft.  Tailwinds are preferred, but, sometimes, a headwind is the only option.  After taking the clouds and terrain into account, this narrows down your altitude to a handful of options.  The winds aloft will further narrow it down.

    Aircraft Performance

    Once you have two or three altitudes in mind, taking a look at the performance charts for your airplane will help nail down that final altitude.  Pull out the POH, compare fuel burn and cruise speed, and you’ll have your altitude selected.

  • Garmin Perspective Missed Approaches

    Are you a Cirrus pilot with a Garmin Perspective?  Still can’t figure out the use of the go around button?  Read on!

    When it comes to flying an instrument approach, we as pilots are assuming we are going to land.  Most of the time, we won’t even take off if the ceilings or visibilities are below the minimums for an approach.  95% of the time, we do land.

    There is the other 5% of the time when something unexpected happens, whether we get a full scale deflection, or we don’t see the runway at the published minimums, and we have to perform a missed approach.

    When instructing, missed approach procedures are actually what I see the most deficiency in when instructing an instrument rated pilot.  It’s not necessarily configuring the airplane for a missed approach procedure, it’s the button pushing involved in setting up the GPS properly.  When a pilot isn’t proficient in the button pushing, that button pushing distracts the pilot from actually flying the airplane, which can lead to a dangerous situation.

    I am going to spend a few articles on flying a missed approach with different GPS and different autopilot configurations.  Today, I will be addressing the Garmin Perspective with a GFC 700 Autopilot, which is what all Cirrus Aircraft after 2009 are equipped with.

    The Garmin Perspective Missed Approach Procedure

    Once the decision to execute a missed approach has been made, here is the step by step procedure:

    • Full Mixture and Full Throttle
    • Simultaneously push the Go Around button on the underside of the throttle.  This does the following:
      • Sets the Garmin Perspective Flight Director to Go Around Mode (7.5 degrees pitch up and wings level)
      • Takes the Garmin Perspective GPS out of Suspend Mode
      • Switches the CDI back to GPS mode if it is in a different mode
      • Garmin Perspective with GFC 700 Autopilot stays on
    • Flaps up
    • Confirm airplane is climbing
    • Set altitude bug for missed approach altitude (assuming it isn’t there already)
    • Set NAV mode and IAS mode on the Garmin Perspective GFC 700 Autopilot

    Garmin perspective

    That’s it.  When Garmin and Cirrus got together to create the Garmin Perspective with the GFC 700 Autopilot, they tried to make as simple but robust system as possible.  Once you have the procedure down for the right buttons to press, then the procedure is relatively straight forward.

  • Garmin 530/430 Missed Approaches

    Flying a missed approach can be stressful enough.  When you haven’t done one in a while and your GPS isn’t showing you how to get to the missed approach point and you can’t remember which button to press, that adds a lot more stress.  Recipe for disaster?  Quite possibly!

    No need to fear, we are here to help.  The procedure for getting a Garmin 530 or 430 to give you missed approach guidance is actually simple and straightforward, if you know what to do!

    Note: Because of the variety of different autopilot configurations in different airplanes, this article will focus solely on the GPS.

    What the GPS is Thinking

    The way Garmin designed the Garmin 530 and Garmin 430 is to be as helpful to pilots as possible.  Their thinking was, 95% of the time, a pilot will make a landing on an instrument approach.  This is pretty accurate as most of the time, this is what happens.  Most general aviation pilots don’t fly approaches to minimums all that often, thus negating the need for a missed approach.

    Garmin Missed ApproachGarmin designed their software with this in mind.  When an airplane crosses the missed approach point, the GPS will go into what’s called suspend mode (a SUSP annunciation appears above the OBS key).  It will keep the missed approach point as the active waypoint because it assumes the pilot is going to land.

    This can be confusing to pilots.  This is what happens when software engineers and pilots come together. Engineers often believe they are smarter than pilots! (See the Airbus fly by wire roll out)

    The Procedure

    In the case of a missed approach, the button pushing on the GPS is actually relatively simple.  There is no SUSP key to take the GPS out of SUSP mode (thanks Garmin!).  Instead, you press the OBS key.  This will take the GPS out of SUSP mode, making the first waypoint on the missed approach procedure the active waypoint.  Your GPS will now give you guidance on the missed approach procedure.

    If you are going missed off an ILS, LOC, or VOR approach, then there is one more key you’ll have to press. Your CDI needle (whether it is digital or analog, an HSI or just a CDI gauge) will be reading off the NAV radio and your CDI indication on the GPS will be VLOC.  After you press the OBS key, press the CDI key on the GPS so you will start getting course guidance from the GPS again.

    That’s it.  Button pressing on the different autopilots will vary, but if you are familiar with yours, you’ll be able to tell it to follow the GPS and climb to the proper altitude.

  • A Proper Cross Country Flight Checklist (Part 1)

    I love cross country flights. Airplanes are designed to travel.  When I was instructing private students, my favorite lessons were always the first cross country flights. I looked forward to getting my students out of the pattern, away from the practice area, and showing them what they could really look forward to as a private pilot.

    When I was in college, my friend and I borrowed his dad’s Cessna 150, did a cross country flight in it from Indianapolis to Kitty Hawk, then down the coast to Florida. We camped in the grass next to the airplane wherever the airport managers would let us and had our own aviation adventure complete with mechanical problems, unexpected weather, and interesting people along the way. These types of trips have produced some of the best memories and experiences that I’ve acquired during my aviation career so far.

    Unfortunately, I know many people whose only cross country flight experience is what was necessary to satisfy their Private and Instrument training requirements. Some of them are nervous about the idea of venturing away from the familiarity of their home airport, while others are relatively new pilots who simply don’t know where to start planning a long cross country flight.

    I’ve taken some notes on my preparations for an upcoming cross country flight that I’ll be flying in my dad’s Bonanza. I’m hoping this checklist might help others feel a little more confident that they have everything they need to get going.

    Oil

    Its always a good idea to bring a few extra quarts of oil. If you stop somewhere and find you need some, its nice to have the right kind on hand. Never assume that the airport you’ll be landing at next will have oil available.

    I like to keep a few extra quarts of 15W50 in the back of the Bonanza, just in case (photo from oil-store.com)

    Fuel Stops

    Here is an example of the 100LL price tool as seen on the Foreflight maps page
    Here is an example of the 100LL price tool as seen on the Foreflight maps page

    I’ve learned the hard way that calling ahead to verify fuel availability can be extremely important. I landed at an airport in Ohio one beautiful Sunday morning to find that the FBO wouldn’t be open until much later in the day. Naturally, there was no other fuel available on the field. I hadn’t called ahead to verify the hours of fuel availability (I assumed they had Self Serve) and had only 2 options: wait a while for the FBO to open, or try and find somewhere else nearby that had gas. As far as price, www.100LL.com is a valuable tool for finding cheap fuel. Foreflight also has posted prices for 100LL and Jet A, but it’s still a good idea to call ahead and verify price and availability.

    Batteries for electronics

    It’s miserable to run out of batteries for a noise canceling headset with hours remaining in your flight. Bring spares, not only for your headset, but for your flashlight and other gadgets as well. Make sure your hand held GPS, iPad, and Stratus are charged (if you have them). I like to carry a charge cable and adapter as a backup so that I can plug things into the cigarette lighter.

    Jumper Cables

    We always carry the ground power cable in the back of the Bonanza just in case we ever need a jump. Last month, when I was flying down to Texas, I was glad I had them; we had a dead battery after our fuel stop and had to borrow some power from an FBO worker’s pick up truck. Don’t assume that wherever you are stopping will have the correct cable to jump your airplane, especially if it requires a specific plug.

    These are the cables we keep in the back of the Bonanza (photo from airchief.com)

    Parking Fees

    Every airport is different. I like to call ahead and find out how much the FBO is going to make me pay in landing/overnight fees. When I flew up to Buffalo last summer, I paid 25 dollars for parking at Niagara International (IAG). Had I parked at Buffalo (BUF), they would have charged me over $200.

    Approach plates and charts

    Make sure you have current approach plates and charts either physically available or downloaded before you blast off. Having a copy of an AFD is a good idea as well, be it digital or paper.

    Rental cars

    If you arrange it beforehand, many FBO’s will have the car ready for you upon arrival. You may also be able to drop the car off at the FBO when are finished, instead of taking it back to the rental agency. It sure is nice to have the car pulled up next to the airplane when it’s time to unload.

    Hotels

    Bigger FBO’s may have discounted rates with local hotels. If you call the desk and explain your needs they may offer to book it for you, or at least point you in the right direction. It may be worth picking an airport with more expensive fuel if it puts you closer to the hotels or restaurants you want to go to.

  • The Flight Director as a Backup

    I’ve noticed that a lot of general aviation pilots tend to ignore the flight director on the attitude indicator.  A lot of pilots don’t even know what it’s there for or how to use it.  Talk to any airline pilot, though, and he or she will tell you how important the flight director actually is.

    In most high performance airplanes, the flight director comes on when the autopilot comes on.  Essentially, the autopilot is following the flight director, which tells the autopilot where to go.  The flight director can also be used with the autopilot off, when hand flying an approach, for example.  By turning the flight director on, it will show you where you need to fly to stay on course and on glide slope.

    Flight Director

    The flight director is most often controlled by the autopilot controller.  The same buttons you use to put the autopilot in heading mode also tells the flight director to follow the heading bug when the autopilot is off.  When you move the heading bug (or change course on the GPS, depending on which mode you have selected), the flight director will show you when you need to turn and when you need to stop turning.  It directs your flight attitude, hence the name.

    I recently discovered it’s a great backup when you have some instruments on the fritz.  I went on a long flight in a steam gauge Piper Malibu and the attitude indicator started reading erratically.  While flying straight and level, it would randomly indicate that I was in a 10 degree bank to the right, swing back and show wings level, then show a 3 degree turn left.  This went on for a while.  We were in VMC conditions, so legality wasn’t a problem, but it was kind of disorienting.

    After a little while of this, the autopilot started acting up.  It would start oscillating the pitch up and down, making it seem like we were going through a moguls course in the air.  I ended up turning the autopilot off and hand flying the airplane.

    This led to a conundrum, since my attitude indicator was unreliable.  I could definitely look outside, since it was VMC, seeing when I was level and when I wasn’t.  That would create a higher workload for me, which on a long flight like I was on, would lead to an increase in fatigue.  The solution?  The flight director!

    I turned the autopilot off, but I left the flight director up.  It wasn’t referencing the bank angle that the attitude indicator was showing since the KFC 150 goes off of the turn coordinator.  So, if I just followed the attitude indicator, I could just keep scanning the instruments and relieve a little bit of my workload.

    It actually worked really well.  By just following the flight director, I was able to stay on course and on altitude with only minor attitude adjustments whenever we hit turbulence.

    So, if you’re attitude indicator and autopilot decide to stop working on you, then bring up the flight director, push the same buttons you would if you were using the autopilot, and it works as a great backup.

  • Calm Wind Landings

    Some of a pilot’s favorite words are heard on the ATIS:  “Winds, Calm.”  These words set off all sorts of happy bells and hallelujah choruses.  Most pilots spend their lives fighting the winds.  On those rare days when the winds are calm, great happiness ensues.

    Limp Wind Sock

    But, are calm wind landings more complicated then everyone thinks?  Well, they can be if the proper planning doesn’t go into them.

    Let’s think about wind.  We have surface wind and we have winds aloft. Sometimes the surface winds are calm.  When this happens, certain airports have preferred calm wind runways which are supposed to be used in these conditions.  Winds aloft are almost never calm.  95% of the time, there is some kind of wind even 100-200 feet above the surface.

    Here is the question pilot’s face when coming into an airport with calm winds: which runway do I use?  Do I use the calm wind runway?  Do I use the runway that is easiest to enter the pattern for?  Do I use the one with the shortest taxi?

    A lot of technologically advanced aircraft have a wind indicator on the PFD. This tool is often forgotten in calm surface wind conditions.  On the contrary, this is probably the most important tool a pilot can have when figuring out which runway to use when the winds are reported calm.

    Here’s why.  That wind indicator is showing the pilot what the winds aloft are. The winds aloft should determine what runway is going to be used.  If the wind indicator is depicting a south wind, then a south runway should be used.  Even if it is a 5 knot wind at pattern altitude, it’ll still be a headwind coming in on final approach.  If the north facing runway is used, that same 5 knot headwind can blow an airplane halfway down the runway before the ground speed drops off enough for it to land.

    So, the next time you are coming into an airport and the winds are reported calm, take a look at your wind indicator on your PFD when deciding which runway to use.  It’ll probably save a few go arounds!
