  • As Fast as a Cirrus — Better Tech, and Less?

    ByHank Gibson
    2008 Cessna 400 Corvalis TT N422TJ on the ramp — a faster, better-value alternative to a Cirrus SR22T
    2008 Cessna 400 Corvalis TT (N422TJ) — 235 KTAS and Garmin G1000 glass, priced under a comparable Cirrus.

    If you’re weighing a Cessna 400 vs Cirrus, start here. The 2008 Cessna 400 Corvalis TT cruises at 235 knots true — the fastest fixed-gear piston single ever certified. It’s faster than a turbocharged Cirrus on the same fuel and the same class of engine, and it costs less than a comparable SR22T. If you’re shopping a high-performance single for speed and value, N422TJ deserves a hard look.

    The Airplane Cirrus Shoppers Overlook

    The Cessna 400 is a Lancair design — a clean-sheet, all-composite airframe built to go fast. Cessna certified and refined it, and built N422TJ in 2008. It seats four, carries a real load, and handles weather. Most buyers shopping a high-performance single default to Cirrus, so airplanes like this one get overlooked. That’s where the value is.

    Faster on the Same Fuel

    The 400’s 235 KTAS is a true max cruise at 25,000 feet on oxygen. A 2011–2012 Cirrus SR22T (Gen 3) trues about 211 KTAS. Both burn 100LL and run turbocharged Continental engines in the same ~310-horsepower class.

    That’s about 24 knots up high — roughly 45 minutes off a 1,000-nautical-mile leg — with no bigger engine and no more fuel. And it isn’t only a flight-levels number: at 10,000 feet the 400 still trues about 180 KTAS, roughly 10 knots faster than an SR22T at the same altitude.

    The Value Gap

    N422TJ is priced at $350,000. A comparable Gen 3 SR22T typically trades between $450,000 and $550,000 used. (A new SR22T is a $1M-plus airplane — not the comparison.) Against the newer turbo Cirrus, that’s roughly $100,000 to $175,000 less for a faster airplane.

    Cross-Shopping a Turbonormalized Cirrus SR22

    A lot of buyers looking at N422TJ also weigh a Cirrus SR22 with the Tornado Alley turbonormalized engine. It’s a fair comparison — the same ~310-horsepower-class Continental, the same all-composite fixed-gear layout, the same 100LL — so here’s the honest math.

    Speed and engine: the turbonormalized SR22 trues around 211 KTAS; the 400 does 235. The 400 also runs a true twin-turbocharged TSIO-550-C, not a turbonormalized system — a true turbo makes boosted power up high, which is a big part of that speed edge.

    Avionics and price — 2006–2008: those Cirrus came with the Avidyne Entegra panel. N422TJ’s Garmin G1000 with WAAS and Synthetic Vision is a clear step up — better glass for comparable or less money.

    Avionics and price — 2009 and later: Cirrus moved to Garmin Perspective (G1000-class) glass, but the price moved with it. A 2009 SR22 turbonormalized with Perspective typically runs around $400,000 or more — one representative listing is $429,900. N422TJ is $350,000: less money, comparable glass, and 24 knots faster.

    The SR22 still brings the CAPS parachute and the Cirrus owner community. But on speed, engine, and price, the Cessna 400 stays ahead.

    The Avionics You Can’t Buy Anymore

    N422TJ has a Garmin G1000 with WAAS and Synthetic Vision (SVT) and the GFC-700 autopilot. WAAS gives you LPV approaches — near-ILS precision at runways nationwide.

    This matters because the WAAS upgrade path for the G1000 in these airframes is closed. A Cessna 400 that left the factory without WAAS can’t be upgraded — it will never fly an LPV approach. So a WAAS-plus-SVT 400 like this one is a scarce find. You either buy one that has it, or you don’t get it.

    Built to Actually Go

    This airplane is equipped to be flown hard and often:

    • Thermawing electric de-ice with a backup alternator — a de-ice system (not certified known-ice)
    • Factory air conditioning
    • Speed brakes
    • Hot prop, built-in oxygen, and ADS-B Out

    An Honest Word: What the Cirrus Does Better

    One thing every Cirrus has that the 400 doesn’t: the CAPS whole-airframe parachute. Pull the handle and the airplane comes down under canopy. For a lot of buyers that’s the deciding factor, and it’s a fair reason to choose a Cirrus. Cirrus also has a large owner community and a strong support network.

    Useful load is comparable across all three airplanes — the 400 is often equal or a little better. If the parachute and the community are your priorities, a Cirrus may be the right airplane, and we can help you find one. If your priorities are speed, avionics, and value, the 400 is hard to beat at this price.

    Cessna 400 vs Cirrus: Quick Answers for Shoppers

    Is the Cessna 400 faster than a Cirrus SR22T?

    Yes. The Cessna 400 Corvalis TT trues up to 235 KTAS at 25,000 feet versus about 211 KTAS for a Gen 3 Cirrus SR22T — about 24 knots faster on the same 100LL and the same ~310-horsepower class of turbocharged Continental engine, or roughly 45 minutes saved on a 1,000-nautical-mile leg. At 10,000 feet the 400 still trues about 180 KTAS, roughly 10 knots faster than an SR22T at that altitude.

    How does the Cessna 400 compare to a turbonormalized Cirrus SR22?

    The Cessna 400 trues 235 KTAS versus about 211 KTAS for a turbonormalized SR22, and it uses a true twin-turbocharged Continental TSIO-550-C rather than a turbonormalized system. A 2006-2008 SR22 turbo has the older Avidyne Entegra panel, while the 400 has a Garmin G1000 with WAAS and Synthetic Vision. A 2009-and-later SR22 turbo with Garmin Perspective glass typically costs around $400,000 or more, versus $350,000 for N422TJ. The SR22 still offers its CAPS whole-airframe parachute.

    Does the 2006-2008 Cirrus SR22 have a Garmin G1000?

    No. Cirrus SR22s from 2006-2008 typically came with the Avidyne Entegra glass panel; Garmin-based Perspective glass arrived in 2009. The 2008 Cessna 400 came with the Garmin G1000, and N422TJ has the WAAS and Synthetic Vision version.

    How much less is a Cessna 400 than a comparable Cirrus SR22T?

    N422TJ is priced at $350,000, while a comparable 2011-2012 Cirrus SR22T (Gen 3) typically sells for about $450,000 to $550,000 used — roughly $100,000 to $175,000 less for a faster airplane.

    What is the fastest fixed-gear single-engine airplane?

    The Cessna 400 Corvalis TT, at 235 KTAS maximum cruise, is the fastest fixed-gear piston single-engine airplane ever certified.

    Does the Cessna 400 have a parachute like the Cirrus?

    No. A whole-airframe CAPS parachute is the one meaningful capability the Cirrus offers that the Cessna 400 does not. On speed, avionics, and useful load, the 400 matches or beats a comparable SR22 or SR22T.

    Can the Cessna 400’s Garmin G1000 be upgraded to WAAS?

    No. The WAAS upgrade path for the G1000 in these airframes is closed, so a non-WAAS Cessna 400 can never gain LPV approach capability. N422TJ already has WAAS plus Synthetic Vision, which makes it a scarce find.

    Does the Cessna 400 carry less than a Cirrus SR22?

    No. Useful load is comparable — the Cessna 400 is often equal to or a little better than a comparable SR22 or SR22T.

  • Introducing…The Aviator’s Academy

    ByHank Gibson

    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

    ByHank Gibson

    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

    ByHank Gibson

    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

    ByHank Gibson

    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.
