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!

  • Unusual Attitude Recoveries

    For a VFR or an IFR pilot, an unusual attitude can be one of the most dangerous situations to get into.  That is one reason so many new autopilots are being developed with a level button.  The concept behind the level button is if the pilot gets into a disorienting situation, press the level button and the autopilot comes on, holding the airplane in a straight and level pitch attitude.

    What about all those planes without autopilots that have a level button?  That’s who this article is for.

    First off, what is an unusual attitude?  The Airplane Flying Handbook on page 4-17 gives the following definition:  “An unusual attitude is commonly referenced as an unintended or unexpected attitude in instrument flight.”  The AFH also goes on to say that an unusual attitude in training has no defined bank and pitch parameters, but “for training purposes an instructor could place the airplane in a 30 degree bank with a nose up pitch attitude of 15 degrees and ask the student to recover and that would be considered an unusual attitude….”

    We now have a basis from the FAA.  VFR Pilots are now saying, “Oh, instrument flight, that doesn’t apply to us.”  Not so fast.  The Private Pilot ACS (and before it, the PTS) has a requirement for Basic Attitude Instrument Flying, including unusual attitude recoveries.  Why?  Because VFR pilots still inadvertently fly into IMC conditions and can get into an unusual attitude.  Plus, a private, non-instrument rated pilot has a higher chance of not recovering from an unusual attitude since he isn’t used to relying on his instruments.

    At each training event I do, whether it be private pilot training, a flight review, IFR training, transition training, or pretty much any kind of recurrent training, I like to do unusual attitude recoveries with my customers.  It’s one of those things that the recovery procedure wanes over time since it isn’t routinely practiced solo (for good reason!).

    I see people have the most trouble with the nose high unusual attitude recoveries.  Let’s start with the recovery procedure, then I’ll discuss the common errors (notice that the nose high unusual attitude recovery procedure mirrors a stall recovery).  Remember, this is in IFR conditions:

    • Breathe
    • Pitch Down to a level pitch attitude on the Attitude Indicator (or lower if the stall warning horn continues to go off)
    • Simultaneously add full power
    • Roll wings level
    • Flaps up and recover to a level pitch attitude if not there already

    The order is important, especially the breathing part.  What happens if a pilot goes straight into a recovery and doesn’t pause for a second or two to absorb what’s going on is the recovery isn’t executed properly.

    Our brains see the wings banked and set off all kinds of alarms to roll the wings level first before doing anything else.  Adding any kind of aileron input with the nose close to the critical angle of attack is a bad idea.  You are adding adverse yaw (since you probably won’t be coordinated) and load factor which increases the stall speed.  Then we all know that Stall + Yaw = Spin.  That’s something that is best avoided in IMC.

    We have to teach our brains to ignore the bank angle until the pitch and power come in.  Once the airplane is far away from the critical angle of attack, then the bank can be rolled to neutral.

    Let’s look at the nose low unusual attitude recovery.  The order is still important on this one too:

    • Breathe
    • Power Reduce (to idle if necessary)
    • Roll Wings Level
    • Pitch up to a level pitch attitude
    • Add Power back to cruise

    The theory with the nose low unusual attitude is your speed is accelerating.  By reducing the power first, that helps reduce the load factor experienced when the pitch is increased.  Same with rolling the wings level.  Neutral bank is a lower load factor than some kind of a bank angle.  We are trying to prevent overspeeding the airplane.  The lower the load factor, the less of a chance we have to rip the wings off.

    The most important step in either recovery procedure is to breathe first, allowing the brain to process exactly what is happening.  That way, the proper recovery can be executed.

  • Casey Aviation Makes Piper PA46 Systems Videos Free

    The safest pilots are the ones who attempt to gain as much knowledge and learning about their airplane and environment as possible. These pilots are the ones who enjoy learning, going to seminars and conventions, and soak up all the MMOPA magazine articles in each issue. These pilots are the ones who get as much training as they can, above and beyond what the minimum requirements are.

    If you are one of these pilots and you own a Piper PA46, then this blog is for you.

    Casey Aviation, one of the best Piper PA46 training companies out there, recently released all of their Malibu, Mirage, Matrix, Meridian, and JetProp systems training videos for free. These are some fantastic videos that Casey Aviation created which go much more in depth than any power point presentation could.

    The great thing about the videos is they give the viewer an all access “inside look” to the specific airplane. Joe Casey, owner of Casey Aviation, takes off cowlings, crawls under the nose gear compartment, and even shows an airplane with the interior out so all the flap cables and environmental systems can be seen.

    I have started referring all of my PA46 customers to the Casey Aviation videos as part of the prep work for our training sessions.

  • Aircraft Purchase: The Logbook & Pre-Purchase Inspections

    Your about to make your dream aircraft purchase.  The plane has low time on the engine, is reasonably priced, and, according to the seller, has no damage history.  You are overjoyed!  Your dream of making an aircraft purchase is finally coming true.  You prepare your offer for the seller, set up the escrow account, and start all the paperwork.

    Two weeks later, the airplane is yours!  You start flying it, though, and the engine starts to have some strange vibrations.  After several flights, it starts to get worse.  You take it to your mechanic to get it looked at and you find out the airplane needs three new cylinders along with some other engine work that is going to total a lot of money.  Plus, your airplane is now going to be in the shop for several weeks.

    All that excitement you just had?  It just went out the window.

    Could this have been prevented?  Probably so, with a logbook inspection and a pre-purchase inspection.

    Aircraft Purchase:  Maintenance Logbooks

    Aircraft Purchase: Logbook Inspection

    Inspecting a logbook can be very daunting when making an aircraft purchase, especially for older airplanes.  This is, however, one of the most vital steps in making a new aircraft purchase.  You can find out many things from looking at the maintenance logs of an airplane.  First, you can check the compression levels of the engine.  Typically, you want compression levels in the 70’s, with it still being okay in the high 60’s.  Anything below 65 and there could be potential problems.

    Second, you can find out if there has been any odd maintenance done pointing to possible unreported damage history.  This is rare, as most aircraft owners are honest and up front when talking about damage history.  But, if there is an entry detailing a prop overhaul after only 50 hours on that prop, you may start to ask some questions.

    Third, you can find out how well the airplane has been maintained.  If a lot of maintenance was completed at each annual, even if it was a lot of small things, then the airplane has been maintained by a good mechanic who is very thorough.  This also involves a check of the ADs, Mandatory SBs, SBs, and SLs that have been issued for the airplane.  If all that has been kept up with, it’s a well maintained airplane.

    Finally, it gives you a good idea of how much the airplane has been flown.  Sure, the ad online will have the total time and time since overhaul, but you can look at the year by year breakdown of how much the airplane has been flown.  It may have been flown a lot earlier in it’s life, but not quite as much recently.  That’s not necessarily a bad thing, but airplanes like to be flown.

    Aircraft Purchase: Pre-Purchase Inspection

    Before making an aircraft purchase, it is extremely vital that whenever you are buying an airplane that you get a pre-purchase inspection done on the airplane.  Even better is getting one done by a mechanic who specializes in that type of airplane (eg. Piper Service Center for Pipers, Cirrus Service Centers for Cirrus, Kevin Mead for PA-46s).  A pre-purchase inspection can save you a lot of money in the end.

    There is always going to be some kind of maintenance issue with an airplane being purchased, whether it is big or small.  Once a pre-purchase inspection is completed, you can take the findings to the seller and negotiate for a lower price based on those findings, or just have the seller fix the items before the sale is completed.

    I would recommend having the seller fix the problems before the sale is completed.  Even though it may take a little longer for the sale to be completed this way, you’ll get to enjoy your airplane right away instead of it being in the shop the next several weeks after you complete the purchase.

    There is the circumstance where the  pre-purchase inspection reveals some serious airworthiness issues which would cause the deal to be voided.  Always put this clause in a purchase agreement, giving you, the buyer, an out if there are serious airworthiness issues.

    When it comes to making an aircraft purchase, it is not a process to be rushed.  Slow and steady usually gets the best airplane for the money, giving you years of enjoyment in the future.

  • Winter Ops

    It’s summertime and the weather is hot! Over this dry, sunny season, winter flying is probably the last thing on your mind. However, now is the perfect time to start getting things in place for winter and that includes having a plan for taking care of your airplane.

    Why are preparations for winter ops needed in the first place? Cold weather, especially during the engine start and warm up period, can be very damaging to your engine if precautions aren’t taken to ensure that safe temperatures exist inside the engine before you turn the key. I always thought that the biggest problem associated with cold weather was engine oil. The logic is since cold oil is thicker and less viscous as the temperature drops, it is not able to circulate quickly throughout the engine to provide proper lubrication upon starting.

    While cold oil may be a factor, the introduction of multi­viscocity oils has greatly reduced that issue. The real problem is created by the different ways that various parts of the engine respond to heat. Because aluminum expands more quickly when heated than steel does, the pistons (made of aluminum) expand more quickly than the cylinders (made of steel). This can lead to scuffing on the sides of the cylinder barrel. In the same way, differential heating can reduce clearances which are designed to provide cooling oil to bearings and other vital engine parts, thereby causing damage which greatly reduces the life of the engine.

    So how cold is TOO cold? Unfortunately, that is a difficult question to answer. Because there is so much variation between engines, airplanes, and environments, there really isn’t any one specific answer. An older, more worn out engine may actually be less susceptible to cold weather damage than a newer, tighter engine because its internal clearances are probably not as tight as they were a few thousand hours ago. I have heard of some people who preheat their airplanes anytime the temperature falls below about 40 degrees. For us northerners, this seems excessive. On our E33A Bonanza which has a Continental IO­520, we generally preheat the airplane when it is cold soaked in temperatures below freezing (32° F).

    Here are a few of the best ways to get your machine ready for a cold weather flight:

    • Heated Hangar:­ Nothing beats a heated hangar for warming up an airplane. The warm air is evenly distributed around the engine and in the cockpit (your avionics and gyros will thank you!). The airplane will need to be in the hangar for a while in order to warm up the guts of the engine. Often, the easiest way is to have the airplane pulled in the evening before the planned departure and left overnight. Many FBOs will hangar airplanes overnight for a small fee and it is well worth the price. We almost always have our charter airplanes put into hangars overnight when on a winter trip to ensure that we don’t have any trouble when we depart the next day. This practice has the added benefit of keeping the airframe clear of any ice and snow that may accumulate before you are scheduled to leave.
    • Electric Engine Heaters­: Multi­point electronic heaters use heating pads that are placed around the engine in order to heat up the various components such as cylinders, the oil pan and crankcase. Most of these systems are designed to be activated by being plugged into a wall outlet with an extension cord. Preheating for a winter flight is as simple as going to the airport the night before and plugging it in. Two well ­known manufacturers of multi­point engine heaters are Reiff and Tanis. These systems are relatively inexpensive and can be a life saver if you regularly travel in colder climates. If an engine heater is the right choice for you, it is recommended to avoid less ­expensive models that heat only the oil pan.

    • Covers and Blankets­: If it is especially cold or you have to preheat outside, having something to insulate the cowling and keep the wind out can be very useful. Regular blankets will work long as you can secure them in place. If you have an ongoing need for additional insulation, there are companies that make custom blankets and propeller covers to fit your airplane. If you are landing and then taking off again relatively quickly, using a few blankets and cowl plugs will work nicely to keep the engine warm while it is sitting outside. In a pinch, placing a couple of powered light bulbs in the cowling overnight with insulation on top can result in sufficient temperatures for starting the engine.

     

    Bonanza Cover
    Even with the multi­point electric heater, we still use a blanket while preheating to help keep everything toasty.

     

    • Forced Air:­ This method is used widely by FBO’s and flight schools. Hot air is produced in a portable heater and is then pumped into the engine compartment via the openings at the front or bottom of the cowling. This method has the benefit of not requiring any additional equipment to be installed on the aircraft beforehand and can be very effective provided there is adequate time for the engine to heat completely before removal.

    • Winter Baffles:­ When the air temperature starts to drop into the teens and lower, you may find it difficult to keep your engine temperatures warm enough in cruise flight. The problem is that the air entering the cowling inlets is so cold that it overcools the engine. The solution is to install additional baffling in the engine inlets to reduce the amount of airflow into the cowling. These additional baffles are usually just sheets of aluminum that are cut to the correct size and are bolted in and removed quickly and easily as needed. Some pilots swear by them while others complain that they can cause uneven cooling. If you have questions about winter baffling, I’d suggest talking to your mechanic about your specific airplane.

    Winter flying can be extremely rewarding. After their hands thaw from pre­flight, a pilot is often rewarded with smooth air, improved performance and outstanding views. Just don’t forget to prepare the airplane for the cold. The preparation is often as simple as plugging in an extension cord or making a phone call to the FBO. So whether you live in the north or the south, take good care of your engine so that it can keep taking good care of you.

  • FICON Reports

    Field Condition, or FICON, reports show up in NOTAMs both during the summer time and the winter time. In the southern states, FICON reports are seen more in the summertime during and after hard rains and thunderstorms (with the exception of winter 2021 & 2022, where Texans quickly got familiar with FICON reports after some very unusual winter weather). In cold winter climates, FICON reports are a staple during the winter season, showing up during and after snow & ice storms.

    The question is, what do those codes mean in the FICON report? You could see 5/5/5, 3/3/3, 3/4/4 and any combination thereof. And why are there three numbers?

    Let’s start with the second question first. The three different numbers in the FICON report indicate the 3 different sections of the runway: the touchdown third, midpoint third, and rollout third of the runway.

    Now, what are those numbers describing? The three numbers are the indication of how slippery that portion of the runway is. This is referred to as a Runway Condition Code (or RCC). The lower the number, the more slippery the runway is. The higher the number, the dryer the runway. The scale is 0-6, with 6 being completely dry and zero being no traction at all.

    Here is the FAA table for the RCCs.

    Now, in order for those RCC codes to generate, at least 25% of the surface must be wet. If there are just spots of standing water, slush or snow, a FICON report will be issued to report the contaminants, but no codes will be generated.

    The Runway Condition Codes are only part of a FICON report. In addition to the codes, a descriptor in the NOTAM will be published describing what percentage of the portion of the runway is affected and by what.

    For example: RWY 28 FICON 3/3/3 100 PRCNT 2IN DRY SN OVER COMPACTED SN.

    Deciphered, that is saying that all sections of Runway 28 have braking deceleration that is noticeably reduced or direction control is noticeably reduced and 100% of each section has 2 inches of dry snow over compacted snow. Sounds like a runway to avoid!

    Braking action reports are separate from FICON reports, but also issued via NOTAM. Braking action reports are issued by the airport manager whereas the FICON reports are computer generated.

  • 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.
