Garmin VNV

The Garmin G1000/Perspective combined with the Garmin GFC 700 Autopilot can be a great tool in descent planning.  When you want to end up at pattern altitude a certain distance from the airport or you get a clearance to cross a fix at a certain altitude, Garmin VNV is a great tool.  Here’s how to use it.

VFR Garmin VNV Use

Let’s say you want to end up at pattern altitude 3nm from your destination, but you don’t want to descend down into the bumps before you have to.  Here’s how to set it up:

  • Go to the Flight Plan page on the MFD
  • Press the ATK OFST soft key on the bottom of the MFD.  It stands for Along Track Offset, which, in laymen’s terms, means you are setting a point along your track a certain distance from your destination.  In this case, it will be 3nm
  • Input the distance using either the keypad or the small FMS knob and press enter
  • Select the altitude you want to be at (in this case pattern altitude) and press enter
  • You will see a point 3nm before you destination appear on your magenta line and a Top Of Descent (TOD) appear where you need to start your descent
  • 1 minute before the Top Of Descent, an indicator will appear next to your altimeter
  • To have the GFC 700 Autopilot fly the descent for you, you have to do two things
    • Set the Altitude bug for the desired altitude
    • Press VNV on the autopilot
  • All you have to do now is manage power

IFR Garmin VNV Use

Let’s say you are told to cross a fix at a specific altitude.  Here’s how to use Garmin VNV to plan it out.

  • Go to the Flight Plan page on the MFD
  • Turn the cursor on and highlight the altitude blank next to the fix in the flight plan
  • Input the desired altitude
  • You will see a Top Of Descent (TOD) point appear along your course where you need to start your descent
  • 1 minute before the Top Of Descent, an indicator will appear next to your altimeter
  • To have the GFC 700 Autopilot fly the descent for you, you have to do two things
    • Set the Altitude bug for the desired altitude
    • Press VNV on the autopilot
  • All you have to do now is manage power

  • After Market Ice Protection

    It’s winter time, so that means winter weather for the aviation community.  For single engine piston pilots, that means dealing with icing conditions.  For us Texan flyers, ice only presents an issue for maybe a week out of the year (the exception being for those Panhandle residents!), but it’s nice to have some protection.

    Most single engine pistons do not come with ice protection from the factory and, of those that do, most are not Flight Into Known Icing (FIKI) approved.  The systems are “get out of jail” systems that can reduce the amount of ice you pick up if you accidentally get into icing conditions and you are on your way out.  The Cirrus SR22 line of aircraft has had the TKS system option since 2006, with the new FIKI system being available since 2010.  The Cessna TTx has a FIKI option that was debuted in 2014.

    The above mentioned airplanes use TKS systems.  There are a handful of single engine pistons that use boots that are FIKI certified:  the Piper PA46 line (Malibu, Mirage, and Matrix) and the Cessna P210 and T210 line (though not all are equipped with boots).

    If you find yourself flying into wintry conditions often and want some protection for your clean wing airplane, there are some aftermarket options for a lot of airplanes now.  Do note that all these systems do come with a pretty hefty price tag, but can be worth it if you fly into icing a good bit.

    CAV Ice Protection TKS Systems

    CAV Ice Protection is a TKS system outfitter.  What is TKS fluid?  According to Flying Magazine:

    “TKS systems dispense an ethylene glycol-based fluid with a freezing point below minus 70 degrees F through porous titanium panels attached to the leading edge of the wing and empennage. The fluid is released through thousands of the panels’ laser-drilled holes, which are not much larger than the size of a human hair. As air flows over the wing and empennage, it disperses the fluid, coating the surfaces, and preventing the formation and adherence of ice.”

    The advantages of a TKS system are the whole entire wing gets coated to get rid of any extra ice that adheres to the top or bottom of the wing surface.  The disadvantage is there is only a finite amount of fluid, so when it runs out, you don’t have any more protection.  The fluid also adds extra weight agains the useful load of the airplane.

    CAV Offers a Basic TKS system for the following single engine piston aircraft:

    • Beech Bonanza
    • Cessna 182, 206, 210, 350, & 400
    • Columbia 350 & 400
    • Piper PA32
    • Mooney M20

    CAV Offers a full FIKI System for the following single engine piston aircraft:

    • Beech A36 & G36 Bonanza, and Baron
    • Cessna 210 & TTx
    • Commander 114
    • Mooney M20

    For more information, check out CAV Ice Protection’s Website.

    Ice Shield De-Icing Boots

    Ice Shield is another after market de-ice option.  Ice Shield makes boots for wing leading edges.  The advantage of boots is they activate instantaneously, getting rid of ice where it builds up first, on the wing leading edge.  No running out of fluid and only the added weight of the system.  Ice Shield also offers heated windscreens for several the Piper Saratoga line and the A36, B36, and G36 Bonanza line.

    Ice Shield has boots for the following single engine piston aircraft:

    • Beech Bonanza F33A and -36 line
    • Cessna 210 line
    • Piper Pa46 line

    For more information, check out Ice Shield’s Website.

    One other company, Kelly Aerospace, makes an electric leading edge de-icer called the ThermaWing for the Cessna/Columbia 350/400 line.  You can read a review of the ThermaWing here, or check out Kelly Aerospace’s website.
  • 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.

  • Oh, Deer (Part 3)

    Read Part 1 & Part 2

    Throughout the whole event, I learned quite a few things both about flying and about myself. Here are some of the lessons which I have taken away from the accident:

    1. No flight is routine: When I took off that morning I was about as relaxed as I could have been while going to fly. I was flying an airplane that I knew well, in beautiful weather, to familiar airports and even carrying passengers which I had taken on this exact trip more than a dozen times. The accident brought into startling clarity that anything can happen at any time. I had done everything right that morning (preflight, weather briefing, planning, etc) , and none of that did anything to stop the deer from jumping out onto the runway. All we can do is ensure the items we do have control over are covered and try to be prepared to deal with anything else that arises. This ties directly into my next point:
    2. Making sure everything is correct: When you do go fly, make sure that you have all your paperwork and personal details taken care of. I can think of a few times over the course of my flying career where something wasn’t quite right with the paperwork, or perhaps I had forgotten my wallet and I was tempted to go fly anyway. “It’s 8pm on Sunday, I’m not going to get ramp checked.” Well, I can assure you that the paperwork and questionnaires which were required to be submitted to the FAA, NTSB, and Insurance companies would have uncovered any discrepancies in my logbooks, currency, or legality. It isn’t worth the risk of flying without having everything in place just in case something happens. It isn’t just a random ramp check which can get a pilot into trouble.
    3. Ask for help: The story of my collision with a deer would have had a very different outcome if it weren’t for the help that I received from countless the people on the ground. If you’re ever in a situation where you could use a hand, don’t be afraid to ask for help. If I had simply turned around and landed back at Wings, I wouldn’t even have had any idea that my landing gear was missing! The people in the control tower, the maintenance guys, the approach controllers in Philly, the emergency responders, and many more people all played their part in orchestrating a successful outcome.

    4. Dealing with the Paperwork: I have had dealings with the FAA before, but never for an accident. I was afraid that the investigation would be a witch hunt and I would have to defend myself while someone poured over all my planning and paperwork looking for potential errors. But, my fears were totally unfounded. Although I did have to answer many phone calls, write many reports, and fill out much paperwork, the FAA, NTSB, and Insurance companies were very patient in waiting for my responses and even complimentary in how the situation played out. I really enjoyed working with all of them and appreciated their encouragement and help.
    5. Emotional Response: After the dust had settled and the smoke had cleared, I was left standing on the side of the runway with the passengers and my boss. I offered to fly them back to Philadelphia or continue to Pittsburgh and assured our Chief Pilot that I was feeling fine and ready to fly again. Fortunately, there wasn’t a need. Over the next week or two, I noticed a change in myself. I wasn’t fine. I have never had headaches, but shortly after I landed I developed a headache that didn’t go away for days. I had trouble focusing on anything and I had trouble finding motivation to do much but sit and stare at a wall. I wasn’t sharp and I caught myself making silly mistakes in my normally routine activities. I wasn’t depressed, or sad, it was just an unwanted mental and physiological response to the stress and shock of what happened that morning in the Baron. I didn’t feel like myself for quite some time and I even found myself a little on edge whenever I lined up for takeoff on subsequent charters for while afterward. Eventually I started to feel normal again, but it was a slow process.
    6. Feather the Props: I can’t tell you what a difference it makes when those props go from wind milling to feathered. It became clear to me that feathering a prop could make a huge difference in deciding the outcome of an emergency situation.
    7. Good training and checklists usage: This one is pretty straight forward, but it’s worth mentioning. Good training and proficiency make all the difference when the odds are against you. Make sure that you use all your resources when your back is against the wall, and that includes the checklists. Under the stress of the flight I had forgotten to close the cowl flaps and would likely have landed with them open without the aid of the Emergency Procedures Checklist. This would have resulted in unnecessary damage to the airframe.
    8. No need to rush: There is no denying that I had things stacked in my favor that day. I had nice weather, extra gas, daylight hours, and even the luxury of landing at my home airport. But, regardless of all those variables, there is no need to rush into anything. Ask questions, find answers and come up with a plan. Obviously not all emergencies present the pilot with the luxury of time, but use all time and resources you have to your advantage.
    9. Polish up those procedures: The deer accident really made me want to go out and brush up on all the emergency procedures which I hadn’t performed since my last checkride. The realization that I could need any of them at any time was really hit home after I hit that deer. Additionally, make sure you know who to call if something ever does happen.
    10. Know the systems: Familiarity with the systems on the airplane makes it easier to troubleshoot and solve issues on the fly and makes it easier to spot a problem in the first place. Knowing how systems work and what their normal indications should be helps make decisions regarding when to divert and where to land easier.

    The irony isn’t lost on me that the last article that I wrote for this newsletter dealt with how to avoid making gear up landings and the high cost required to repair one. I never would have imagined when I wrote that article last fall that I would be writing one only a few months later detailing my own gear up landing.

    The bottom line is that there is nothing a person can do to prepare for every situation which might arise throughout the course of a flight, and it’s also impossible to know which emergency you may have to deal with if a situation arises. All we can do is stack odds in our favor by making sure that we address the things within our control such as aircraft maintenance, careful flight planning, checking weather, and having personal minimums set in place to keep us from flying outside of our skill sets and comfort zones.

    Additionally, ensuring that you are knowledgeable and proficient in your aircraft’s procedures will give you the best chance for success. When things start going wrong, keep calm, and ask for help. Work the problem instead of guessing or rushing into a less than desirable solution. No one wants to be caught in an emergency like a deer in a landing light!

  • Avidyne Vantage

    For years, Cirrus owners who have the Avidyne Entegra PFD and MFD have been clamoring for Avidyne to come up with some sort of upgrade. The Entegra, or EX 5000 system, is late ’90s technology and, though it still works, there will be a certain point in the future when it gives up the ghost. Avidyne still supports the Entegra system, but it’s hard for a Cirrus owner to see all this new technology coming on the market while not being able to upgrade the original Avidyne screens.

    Avidyne gave it a go in the late 2000s with a panel upgrade known as the R9. The R9 was a good system, but Avidyne was very slow on the release (rumors were the company wanted it to be absolutely perfect before releasing it, which frustrated Cirrus, who then switched to the Garmin Perspective panel, leaving Avidyne behind) which led to the R9 only being available as a very expensive retrofit to the Entegra system ($80,000-$90,000 for the system and install). Needless to say, there weren’t that many takers.

    Late in 2020, Garmin announced it had received certification to retrofit Avidyne Entegra equipped Cirrus Aircraft with the company’s G500 TXi displays, which gave new hope to G1, G2, and G3 Cirrus owners. The price tag wasn’t outrageous, coming in at $16,000 apiece for each display. The G500 TXi works with any possible GPS that can be installed in a Cirrus (GNS 430Ws, GTN 650s, GTN750, or the Avidyne IFD 540/440) and with the DFC 90 Autopilot (if the Cirrus is still equipped with an STEC 55x, the Autopilot would need to be changed to either a DFC 90 or a Garmin GFC 500).

    Fast forward to June of 2021 and Avidyne re-enters the game with the Avidyne Vantage. After the R9 debacle, Avidyne has opted this time to go for a more simple approach. The Avidyne Vantage system changes out the Entegra PFD and MFD with bigger screens (12″; Garmin’s TXi units are only 10.6″) with high quality pixelation, synthetic vision, engine gauges, checklists, charts, a hybrid touch interface, and all the other information that was offered on the Entegra system, just all more modern and updated. The best news is that the system provides redundant reversionary mode, which was one of the biggest complaints about the Entegra system.

    The price tag comes in lower than Garmin, with each screen being priced at $12,500. The units will work seamlessly with the Avidyne IFD Series GPS units, though, as of this writing, it isn’t clear if the Avidyne Vantage will work with Garmin GTN 430Ws or the GTN 750/650. I would assume that the integration would be there, but I haven’t found any documentation stating that yet. DFC 90 Autopilot integration would be seamless, but not sure the integration with the STEC 55x or Garmin GFC 500.

    Avidyne says the Vantage will be fully certified in early 2022, but the company is taking orders now. Visit the Avidyne Website for more information.

  • Garmin Smart Glide

    Recently, I was training a customer who had a brand new instrument panel installed in his TBM 700. The avionics shop that did the work (Abilene Aero, who I highly recommend for any panel installs, located at KABI) told us when we picked the plane up that the new Garmin GTN 750Xi had the most recent software update, which included the Garmin Smart Glide.

    I had never used the Garmin Smart Glide before, so I was eager to check it out during our training. When we got to engine failures, we pushed the Emergency button on the Home page of the GTN 750Xi, and then the magic happened.

    The plane was also equipped with a Garmin G600TXi PFD and the Garmin GFC 600 Autopilot. In order for Smart Glide to work, there has to be either a GTN 750Xi or GTN 650Xi installed, along with a G500TXi or G600TXi and a Garmin Autopilot. Garmin is working on getting the legacy G500 as well as the GI 275 and G5 to work with the above GPS units for Smart Glide as well.

    Here’s what happens. The plane loses it’s engine. The pilot’s workload and stress level suddenly goes way up. Trim the airplane for best glide, find the nearest airport, attempt restart. Do it quickly so you have time to focus on the glide. Oh yeah, squawk 7700 and declare your emergency. All the while plummeting toward the ground in a somewhat controlled crash. Yikes.

    Garmin Smart Glide takes over the flying part, allowing the pilot to handle the restart, while making it much easier to squawk, talk and plan the engine out landing. On the home page of the GTN 750Xi/650Xi, the pilot simply taps the Emergency icon on the bottom of the screen. The Autopilot comes on and goes into IAS mode and maintains best glide while descending. The GPS immediately analyzes the Glide Advisor, and turns to the nearest airport in the glide ring (if there is no airport within gliding distance, the GTN 750Xi advises the pilot). Then, the Autopilot flies directly to the Nearest airport, allowing the pilot the ability to take attempt a restart.

    Once it is determined that the engine won’t start, the Garmin Smart Glide has excellent situation awareness tools. On all screens, the pilot is constantly being advised of how high AGL the plane is currently, while advising also of how high AGL the plane will be over the airport that the glide is set up for. There is also a short cut on the screen to tap to squawk 7700 as well as runway length information at the airport.

    The Garmin Smart Glide Button wasn’t installed yet in the TBM, but that will make things even easier when it is (it will be certified in January). This is amazing technology that all Garmin GTN 750Xi pilots should have their software updated to. Remember, you have to have a Garmin Autopilot and a Garmin PFD for it all to work.
