Night Flying

Ah, fall is finally here.  In Texas, it arrived about a month late, but showed up with a vengeance.  A strong cold front caused a 40 degree temperature drop in 12 hours earlier this week, bringing rain, lower freezing levels, and lots of wind.

Fall means cooler temps, but fall also means less light.  The sun begins to set sooner, plus the fall back time change in November cause darkness to spring upon an unaware pilot.

Before getting in to too many night landings tips, just a friendly reminder, passengers can only be carried at night if the PIC has completed 3 takeoffs and landings to a full stop in the last 90 days during the time period of 1 hour after sunset to 1 hour before sunrise.

Lots of us have been landing long before sunset for most of the past couple of months, so those night flying skills might be a little rusty.  The best way to remedy night flying rustiness?  Call an instructor and go get some practice.

In the meantime, here are some tips as to what to expect for your next night flying experience.

  1. Your Eyes Are Very Important.  This may seem like an obvious statement, but night vision can be affected by many things.  Before you takeoff, you want to make sure you can see in the dark.  The FAA recommends no bright lights 30 minutes prior to takeoff.  They also recommend using oxygen at night as this greatly improves night vision, even at low altitudes.  Use off center viewing to help spot traffic or other objects in the air.  Finally, when preflighting, use a red flashlight as much as possible, but if you do have to use a white light, close one eye to keep one eye from being blinded.
  2. Utilize Approach Lights on Landing.  Night landings are very different then day landings.  It is very difficult to get the proper depth perception, not too mention see obstacles below you on your final approach to a runway.  PAPI’s, VASI’s, and instrument approach glide slope’s become very important.  If you are VFR only pilot, if your airport has a PAPI or a VASI, keep 2 white and 2 red (or 1 white and 1 red) lights.  If you see 3 red (or 2 red), climb.  If you see 4 red, definitely climb.  If you are an IFR pilot, I highly recommend always flying an approach at night.  What if your airport doesn’t have a PAPI, VASI, or approach with a glide slope?  You might not want to utilize it at night.  One side note on VFR flight: Clouds are nearly invisible at night.  If you do fly into a cloud (a clue is your strobe lights start reflecting back at you), don’t panic.  If you have an autopilot, turn it on and execute a 180 degree level turn.  If you don’t have an autopilot, start scanning your instruments, keep your attitude indicator blue side up, and make a shallow 180 degree while maintaining altitude.  Then call ATC, advise them what happened, and ask for help.  One more note:  I highly recommend that if a pilot finds that he/she will fly at night at lot, get an instrument rating and fly IFR at night.  It’s much safer.
  3. Practice Landings Before Carrying Passengers.  The tendency when landing at night is to level off too high before flaring, causing the airplane to bleed off speed and energy too high above the runway.  This can lead to a stall, a hard landing, and/or too high of a pitch attitude at touch down causing a tail strike. A good tip is start your level off when you can see the tire marks on the runway.  Make sure you practice night landings, preferably with an experienced instructor who is night current and proficient, before carrying any passengers on board, even if you are night current, but haven’t landed at night in a while.
  4. Night Emergencies.  For engine failures at night, you are very limited on options.  Unless you have a Cirrus equipped with a CAPS parachute system, you really have two options if an airport isn’t within gliding distance.  Find a wide, lighted road that appears to be lightly trafficked.  A word of caution, though:  be careful of light poles, fences, concrete medians, cars, and buildings.  The LA freeway would not be a good option (though there are exceptions to this rule as is evidenced by the picture below).  The second option is find a dark spot and pray it’s a field (or the Hudson River).  As you get closer, you can turn your landing light on to see what the ground looks like.  If it looks good, keep the light on and continue.  If you don’t like what you see, turn your landing light off and continue….

Flying at night can be the best time of day to fly.  It’s usually smoother, cooler, and you get to see all the city lights.  It is a very different environment, however, so make sure to get some training before darkness settles in on your next trip.

  • Breathing…It’s The Difference in Engine Performance

    The PT6 engine that’s found on the Jetprop and Meridian is designated a -21, -34,-35, or a -42A.  The Continental engine on a Malibu is either a TSIO 520 or a 550.  What’s the difference? Why should I care? Most pilots don’t understand the difference, but it’s pretty easy to understand…and it’s all about breathing.

    Whether a piston or a turbine, the engine has a ratio of fuel/air that works best.  For a piston model, we can make adjustments to this ratio by adjusting the mixture.  In climb we use a richer ratio to help cool the engine, and in cruise we lean the mixture to save fuel since we don’t need the extra fuel for cooling (due to higher speeds which cools the engine). In the turbine, the ratio is set and there’s nothing that can be done about it…except climb to a higher altitude.  But, more about that in a second..let’s go back to the piston discussion…

    Piston: A Continental 520 engine and the 550 engine are flown exactly the same.  On takeoff, both will develop 310HP (38″MP with the 520, 35.5″MP with the 550).  So, why would a pilot want a 550 in his airplane as opposed to a 520?  The answer is breathing.

    A 520 is named appropriately because the engine displaces 520 cubic inches of air with each complete cycle of all 6 cylinders.  To determine the displacement, just figure the bore (diameter of the cylinder) and the Stroke (how far the piston travels in the cylinder) and plug the numbers into this formula:

    CID = Bore X Bore X 0.8754 X Stroke X # of Cyl.

    Here’s the bore and stroke of the Continental 520 and 550 engine:

    TSIO 520:  Bore = 5.25″ and Stroke = 4″
    TSIO 550: Bore = 5.25″ and Stroke = 4.25″

    So, you can see the two engines are exactly the same except the 550 has a little longer stroke, and therefore displaces a little more air.  Said another way…it the sucks the air into the engine a little better.

    So, with this knowledge, the ability for the engine to breathe becomes a little more clear.  Both a 520 and a 550 will perform exactly the same until the point that a 520 simply cannot suck enough air and begins to develop less MP as a result.  For most 520 engines, this will happen somewhere around 18,000 ft.  But, it is dependent upon a myriad of factors including: health of the engine, altitude, temperature, and atmospheric pressure. When the 520 hits this point, the throttle can be full-forward, but the engine will not develop full MP, but some number that is less.  I’ve seen a max MP at FL250 in a 520 Malibu to be about 31″MP.  So, you can probably guess that the rate of climb will correspondingly suffer as the engine develops less MP.  How do we fix this problem?  Enter the 550…

    Since the 550 displaces more air, the engine will maintain max MP to a higher altitude.  When the 520 begins to develop less power at about FL180, the 550 engine will be able to continue to maintain 35″ at a higher altitude.  Make no mistake…the 550 will also hit an altitude where is cannot develop 35″MP, but this altitude will probably be nearly FL220.  So, the 550-powered Malibu will reach cruising altitude faster than the 520.

    But, at cruise both engines are pulled back to 30″MP.  So, either engine will deliver the same cruise speed because they are both able to develop 30″MP at any altitude.  Does it really matter if you’ve got a 520 or a 550 engine?  Answer: not much.  Both are excellent engines and both will deliver the airplane to the destination, but if the chosen altitude is above FL180, the 550-powered airframe will probably arrive a few minutes earlier.  Which would I want if I were purchasing an airplane?  It’s not a big enough deal, IMHO.  I’d select the best airframe/engine/prop combination and not put much weight into the 520 vs. the 550.

    Turbine world: So, how about the -21, -34/35, and -42A compare?  Here, there’s  big difference, but it’s still all about the breathing.  A -21, -34/35, and -42A are all derivatives of the famous PT6 family of engines, and all are designed to be 1000+SHP engines de-rated to fit the airframe.  For instance, the -42A engine is 750SHP when mounted on a King Air 200, but the same engine is derated to 500SHP when mounted on the Meridian.  Ditto with the -21 and -34/35 engines…all are de-rated.  So what’s the difference? Breathing…

    At the lower altitudes all will develop their maximum rated SHP, meaning they will all develop maximum torque.  And, down low there’s plenty of air to breathe so the engine has no problem developing that torque at a low ITT.  But, as altitude is gained, the engine must suck more air to develop the same torque, and the ITT goes up.  At some point in the climb (depending upon altitude, temperature, pressure, and IAS) the engine will not be able to produce max torque without exceeding Max ITT.  At this point, the engine cannot breathe any more (suck in anymore air), and the power (torque) developed falls off.  With the -21 engine, the power falls off quite dramatically because the engine simply cannot breathe well.  It is a smaller engine and more air cannot be forced into the compressor section.  For the rest of the climb the engine is “ITT limited” and the performance will suffer.

    The -34/35 engine is a little bigger and will develop maximum power (torque) to a higher altitude.  And, when the torque does drop off (as altitude is increased), the rate of decrease is less because it can breathe easier due to it’s larger size.  Guess what? The -42A will beat out the others and develop max torque to an even higher altitude.  With this decrease  in torque available also comes a welcome friend…less fuel burn.  Altitude is the friend of any turbine pilot, and he/she will climb to the highest altitude possible to save on fuel.

    The end result is the -21 powered Jetprop will cruise at 238 KTAS (in the summer) with a fuel burn of only 28gph.  The -34 will have higher torque than the -21 and will develop more SHP and will have a higher cruise (260 KTAS in the summer) with a correspondingly higher fuel burn (32gph).  The -42A will be breathing easily at higher altitudes, and will develop the most torque, but with a fuel flow of 39gph.  The Meridian (with the -42A) will not out-perform the -34/35 Jetprop in cruise purely because the Meridian is much heavier.

    Just remember…fuel flow in a turbine is always commensurate with its ability to breathe and a turbine’s ability to breathe is a function of the engine’s ability to breathe.

    With this knowledge…let’s check your understanding.  Answer this question: Will a Jetprop cruise faster in the summer or winter?  Remember, cold air is more dense than warm air, and an engine will develop power according to it’s ability to suck in air.  More air available, more power available.  Answer: Winter.

    A good analogy: I’m a Cross-fitter (meaning I do crossfit workouts a lot).  In the gym we have various workouts that test a person’s ability to perform.  Guess who usually does the best?  Right…the guy who can breathe the best.  A person is nothing more than an engine…we intake air and combine it fuel and burn it to develop energy.  In Crossfit, the person with the biggest engine (muscles that can develop power) that can sustain power (good aerobic capability) will win almost every time.  The only variables then are genetics (how well-made is the engine), flexibility (you’ve got to be able to get into the position), and skills (there are more efficient movements).  A good Crossfitter will work hard on mobility, skill, and try to increase the bodies ability to increase capacity through a tough workout.

    To get maximum performance, the pilot cannot change the engines skill or mobility (at  least not without an engine change!), but a thorough understanding of the how the engine breathes will help him/her use the power that is available to the fullest.

    Joe Casey’s aviation story began in 1990 with his first flight near Nacogdoches, TX in a Cessna 172. From lift-off, Joe knew he would have a lifetime passion flying just about anything that will leave the ground…He was completely hooked.

    Along with being an FAA Designated Pilot Examiner (DPE), Joe is an ATP/CFI-AHMG and Commercial Rotorcraft/Glider Pilot in the civilian world and also a UH-60/AH-64 Pilot-in-Command/Instructor/Examiner Pilot in the US Army Reserves.  His passion for the last 19 years, however, has been the PA-46 Malibu/Mirage/Matrix/Jetprop/Meridian. Has has amassed over 6,500 hours in various PA-46 airframes and believe it to be one of the finest flying machines available for the serious cross-country pilot with an eye for efficiency.

    Now, Joe has flown more than 12,200 hours in just about every imaginable environment. Whether providing initial/recurrent training in the PA-46’s, TBM’s, instructing in NVG’s in a UH-60 Blackhawk, flying the King Air series of airplanes, giving tailwheel endorsements, or taking kids flying for the first time, he simply loves flying machines and the people who fly them.

  • Cirrus Announces The New Cirrus G6 SR20 & SR22

    Earlier this month, Cirrus announced the new Cirrus G6 SR20 and SR22.  To the naked eye, they look like incredible airplanes.  There is new lighting and the updated Cirrus Perspective+ avionics in both models, plus the SR20 is now a Lycoming powered airplane.

    The Perspective+ in the Cirrus G6 is based on Garmin’s G1000 NXi platform.  The keypad is updated to a QWERTY keypad, allowing for quicker inputting of data since our fingers are already used to the setup.  A home button was added to the center stack to get back to the map page without having to hold down the CLR key.  The bug knobs were moved down to the autopilot, while the display of the GFC 700 was altered slightly to match the Vision Jet setup.

    Cirrus G6 Perspective+

    The Perspective+ also boasts a 10-fold increase in processor speed, allowing the system to move quicker than the standard Perspective.  The ability to wirelessly update databases has also been included.

    The exterior of the Cirrus G6 SR22 and SR20 models has changed as well.  Cirrus has added the Spectra wing tip lighting system to the Cirrus G6.  It incorporates an entire light panel that runs the length of the wing tip.  The LED dual strobe setup helps with aircraft visibility and ramp appeal.

    Cirrus G6

    The SR20 engine has been changed to the Lycoming IO-390, 215 HP engine.  The Continental IO-360-ES 6 cylinder engine comes out of the SR20 and the 4 cylinder Lycoming goes in.  2 less cylinders will help with useful load and the extra 15 HP will help with takeoff and climb performance.

    The new Cirrus G6 is available for order and delivery immediately.  To read all the details and specs on the Cirrus G6, you can check out Cirrus’ website.

  • Flying Through Rain

    For the most part, flying through rain is a non-event. If the NexRad or Radar is showing light green or dark green, usually there aren’t that many bumps and your plane just gets a wash. Sometimes the visibility drops down a little bit making us IFR pilots have to transition to our instruments.

    It get’s a little more exciting when the precipitation on your screen turns to yellow. This means there is a lot more precipitation echoes either in the clouds or coming out of the clouds, meaning harder rain. I usually tend to stay away from yellow unless it’s absolutely necessary to go through it.

    I had a situation a few weeks ago where I deemed it necessary to fly through some yellow NexRad returns. I was flying a G1000 Columbia into Monroe, Louisiana, KMLU. The winds were mostly light, but slightly favoring runway 04, which was the runway in use. As I got closer, a decent size rain shower with mostly yellow returns was sitting over the final approach fix for runway 04 and slowly tracking to the northeast.

    I didn’t particularly want to spend the entire approach getting beat on with rain, so I decided to fly the RNAV 14 approach at MLU and circle to land on runway 04. The rain hadn’t quite reached the airport yet, so I decided that circling to 04 should be no problem.

    I started the RNAV 14 at the FLESH IAF. Since I was approaching from the west, I did not need to do the procedure turn, so I joined the Final Approach Course (FAC) after crossing FLESH.

    In the meantime, that rain shower was inching closer to the FAC for the RNAV 14. I wasn’t concerned about my safety if I flew through some of it and I didn’t have passengers on board who would get nervous, so I elected to continue. I wasn’t seeing any lightning coming out of the clouds, so it appeared to only be moderate rain.

    Just before I got to JIVEY, the FAF, I entered the clouds and the rain. About 20 seconds later, my altimeter and airspeed started bouncing around a lot. Now, based on all I’ve said so far, what would cause that, and what would you do?

    (Jeopardy theme song playing while contestants ponder questions)

    The answers? Due to the moderate precipitation, water had gotten into my static port and caused the unusual readings on my altimeter and airspeed indicators on the G1000.

    I had experienced this before, so I knew what to do. I reached down and turned the static source from primary to alternate, which starts taking static pressure from inside the cabin in the Columbia. Instantly, everything went normal.

    The other time I had experienced this was also in a Columbia, so I’m under the impression that the way the Columbia static ports are designed, they are a little bit more susceptible to water creeping into them than other airplanes.

    Moral of the story? If your pitot/static instruments start jumping around, the first thing you do is turn your alternate static source on.

  • Epic E1000 Gets the GFC 700

    When the Epic E1000 was finally certified in the spring of 2020, there was much celebrating across the aviation world. Epic Aircraft expended a lot of time and energy getting the E1000 certified and into production (more information on that journey here and in Flying Magazine here).

    The airplane is amazing. In the single engine, 6 seat turboprop market, it easily blows away the competition. With it’s 1,200 SHP PT6-67A, it has double the horsepower of the M600 (600 SHP), and 350 more horsepower than the TBM 940 (850 SHP). It’s 60 KTAS faster than the M600 and, even though the TBM can keep up (both airplanes have equal top cruise speeds of 330 KTAS), the Epic E1000 can carry a payload of 1,024 pounds with full fuel, while the 940 can only carry 584 pounds with full fuel. The TBM carries about 15 minutes more of fuel, but to me, that’s pretty negligible.

    Did I mention climb rates? The E1000 climbs at an average of 1500 FPM at Vy (it’s capable of 4,000 FPM), making it to 25,000 feet in 10 minutes. The TBM climbs at 1000 FPM, taking 13 minutes to climb to the same altitude, while the M600 settles in at about 800 FPM, reaching FL250 in 21 minutes.

    If you expand the comparison to include the Pilatus PC-12, the two airplanes have 1,200 SHP, but the Epic is 50 KTAS faster and they both have about the same weight carrying ability.

    In the most important arena, price, the E1000 is around a million dollars cheaper than the TBM 940.

    The one drawback to the Epic E1000 that immediately was noticeable was the autopilot. Epic originally installed the STEC 2100 autopilot to pair with the G1000 (and later the G1000 NXi). Epic decided to stick with the STEC 2100 through certification for the plane since that autopilot was on all of the E1000s paperwork going through all the levels of FAA approval. To change to the GFC 700 during the certification process would have been a massive undertaking that probably would have delayed certification.

    The STEC 2100 is a good autopilot, but, as any G1000 pilot can tell you, the lack of integration between any STEC autopilot and Garmin panel leaves some to be desired. Not all the bugs talk, which often requires dual data entry, which can lead to forgetting to do both the bug and the autopilot when things get busy. Hello, altitude deviation.

    The goal for Epic was never to leave the STEC autopilot in the airplane. The first E1000s were rolled off the line with the STEC, but Epic didn’t take long to change the autopilot to the much more integrated Garmin GFC 700. That took place this winter (2020), and the E1000 received it’s first upgrade, with Epic dubbing the airplane the Epic E1000 GX.

    I expect the innovators in Bend, OR, where Epic is based and where tons of innovation in aviation happens (Lancair/Columbia started in Bend while RDD is based there as well), to quickly come out with more avionics upgrades for the airplane. I wouldn’t be surprised to see a G3000 version at some point, complete with auto throttles and the new Garmin Autoland. Epic would be smart to follow in the steps of Daher and offer two models, one with the G1000 and one with the G3000 (the TBM 910 has the G1000 NXi while the TBM 940 has the G3000).

    I have yet to fly in an Epic E1000, but I would certainly jump at the chance to do so. Someone asked me yesterday what airplane I would buy if I had a blank check. With the GFC 700 now in the Epic, it would absolutely be the E1000 GX.

  • 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.

  • Hold Anywhere

    The latest Garmin software version on the Garmin G1000 and Cirrus Perspective by Garmin has a really neat feature.  It gives the pilot the ability to create a hold at any fix, VOR, NDB, or even airport.  If the point is in the GPS database, a hold can be created over it.

    How does it work?  Here are the steps.

    Let’s say ATC tells you to hold over an intersection on a Victor Airway that you are already on.  Since you are tracking the airway already, the airway should be in your flight plan complete with all the waypoints on it.

    Bring up your flight plan and highlight the waypoint to hold at.  Press the menu key.  Using the big knob, scroll down to highlight the hold at waypoint option at the bottom of the bottom of the menu.  Press enter.

    garmin-holding-pattern

    Now you can build the hold.  You select what the inbound or outbound course will be.  Select a timed hold or a distance hold.  Then select left or right hand turns.  You can even input your expect further clearance time.  Press enter and now you have a hold as a waypoint in your flight plan.  Assuming you have a WAAS unit, the autopilot will fly the hold for you.

    If you are ever told to “Hold Present Position,” Garmin has you covered.  Simply press menu on the flight plan page, scroll down to Hold Present Position, then follow the prompts on the screen to build a hold at your present position.
