Imagine this …

You have plans to fly to an airport 218 miles north for a business meeting. Your window is tight; you have an early morning meeting at your office you can’t miss prior to leaving for the airport. The colleagues you are flying to meet must catch another flight within two hours of your target arrival time. 

You’re comfortable flying in the current weather conditions, but a small southward-moving storm north of your destination might threaten your approach. Additionally, given the time of day, you can expect ATC delays due to vectors and know you’ll have to adjust on the fly.

Are you confident you can make the meeting in time?

If the answer isn’t immediately clear, you’re not alone. Good aeronautical decision making is of utmost importance in the air. External pressures, unexpected challenges, and your level of instrument proficiency are among the many factors to consider when considering an IFR flight. 

While we can’t remove the external pressures or control the weather, we CAN help with instrument proficiency!

Introducing … The Aviator’s Academy – advanced online pilot training. 

During my time training hundreds of capable and competent pilots at Texas Top Aviation, my most common observation with seasoned and rookie pilots alike is that the pilot is often aware of knowledge gaps with the airplane’s avionics after initial flight training or after upgrading to a more advanced airplane, but aren’t sure where to get answers.  Simply put – expert glass panel flight training is hard to find.

They know enough to have earned their license, but still feel uneasy anticipating unexpected challenges. This leaves them feeling at best, uncomfortable, or worse, on edge and unsafe. When you’re not as proficient as you could be, an easy flight can become stressful quickly in unexpected scenarios, and things spiral from there. It doesn’t have to be this way.

That’s why The Aviator’s Academy offers online courses with real-life scenarios using glass panel avionics. You’ll gain more confidence in the air and be equipped with better aeronautical decision-making skills after learning from the best in the business.

We understand the pressures you face in the air. We get it because we have been providing expert, personalized, owner/pilot instruction since 2014 at Texas Top Aviation. With over 8000 hours of instruction given in Technically Advanced Aircraft and over 13,000 hours in total flight time, The Aviator’s Academy instructors are qualified to fly and instruct most single-engine aircraft to a level that far exceeds what a flight school can provide. Nowhere else can you get expert glass panel online instruction for Technically Advanced Aircraft.

If you’re in need of an instrument proficiency check and fly a technically advanced aircraft with glass panel instruments, this is the place to get your ground school training. Conveniently online. Expertly taught. 

Mastering your glass panel avionics isn’t impossible. You just need a guide. Enroll in the course you need to take your skill to the next level. You’ll receive expert, specialized online training. Then you’ll fly with confidence.

Garmin GFC 600 Autopilot Certified for the Piper Meridian

0 Comments

In the fall of 2021, Garmin announced the long awaited confirmation that the Garmin GFC 600 autopilot is now certified for the Piper Meridian. The Garmin GFC 600 autopilot has been certified for all other types of the Piper PA46 line of aircraft, but the Meridian was last in line. The airplane has to have been manufactured prior to 2009 and have Avidyne avionics, Meggitt, or have been retrofitted with a Garmin G500 (no G1000 aircraft since those already have the GFC 700 autopilot).

The Garmin GFC 600 autopilot is the ultimate digital autopilot. The integration with the Garmin G500, GTN 750 and GTN 650 units is a beautiful thing. The autopilot communicates with all the heading and altitude bugs, flies approaches smoothly, and even has a level button.

In the latest technological marvel from Garmin, Garmin Safe Glide, the GFC 600 autopilot is critical in reducing pilot workload in an engine failure situation. It flies the airplane for you and takes you to the nearest airport, reducing the stress and allowing the pilot to troubleshoot the situation.

Texas Top Aviation recommends Abilene Aero in Abilene, Texas for any and all avionics installs. They have worked with several of our customers in the last year, are extremely knowledgable and do excellent work. Call them for a quote on a new Garmin GFC 600 autopilot in your Piper Meridian.

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.

Flying WAAS GPS Approaches

1 Comment

When flying a WAAS GPS approach, there are several different levels of WAAS signal that a GPS receiver can get. The most precise is an LPV signal. LPV stands for Localizer Performance with Vertical guidance. An LPV approach has the lowest minimums of all the WAAS GPS approaches, typically in the range of 200-300 feet AGL. A GPS glide path (GP) is guaranteed with an LPV approach and the minimum altitude is a decision altitude (DA).

Just like a localizer, an LPV course width get’s tighter and the CDI becomes more sensitive the closer the plane get’s to the runway. Even though the LPV approach minimums are so low and the approach is down to a DA, they still aren’t considered precision approaches by the FAA (which leads to some extra planning when selecting an airport as an alternate that only has GPS approaches, since the AIM specifies only the LNAV minimum are to be considered if an alternate airport only has GPS approaches, bringing the 800 foot ceiling requirement to bear)

An LNAV/VNAV approach is still a WAAS approach that has a GPS glidepath, but is slightly different than an LPV approach. An LNAV/VNAV final approach course does not get more sensitive the closer the plane gets to the runway. The smallest course width on an LNAV/VNAV approach is 0.3 miles either side of center. LNAV/VNAV approaches will, most of the time, have higher minimums than LPV approaches and can have minimums no lower than 250′ AGL.

The third type of WAAS approach is strictly a non-precision approach with a Minimum Descent Altitude (MDA). These are designated LP approaches, which stands for Localizer Performance. These are like old school Localizer only approaches that, similar to the lateral portion of an LPV approach, the course width tightens the closer to the runway that a pilot is. There is no glide path by definition of an LP approach, though there is a caveat.

Now, by looking at an approach plate that is a WAAS approach, but only has LP minimums listed, a pilot would assume there would be no glide path. Depending on what type of GPS unit the airplane has, that pilot could be wrong. Garmin Perspective units (Cirrus G1000), all GTN 750s and GTN 650s, All G1000 NXi units, most Garmin 430W and 530W, and all Avidyne IFD 550/540 and 440 units will display an advisory glide path on an LP approach, designated LP+V.

What does LP+V indicate? An advisory glide path is just advisory, but it is totally legal to follow down on a non-precision LP approach. The kicker is obstacle clearance is not guaranteed and the pilot needs to keep an eye on minimum altitudes at the different waypoints on the approach. The big thing I tell people is, when you arrive at the MDA and the runway is in sight, following the advisory glide path below the MDA could get you in trouble with obstacles. Don’t just hone in on your instruments when you break out of the clouds. Look out the windscreen and make sure you won’t hit anything.

If you arrive at the MDA on the advisory glide path and the runway isn’t in sight, DON’T GO BELOW THE MDA! Most autopilots won’t level off at the MDA, even if that altitude is set in the altitude pre-select, so this will involve turning off the autopilot before the MDA and manually leveling off, or engaging the altitude mode of your autopilot at the MDA.

One other type of GPS approach that you will encounter is an LNAV approach. This is a non-WAAS approach down to an MDA, but your GPS unit may still give you a +V. Most modern ones will.

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.
