    Nobody seems to know. But we are curious.

    The PT6A has two gear boxes—a beefy one up front spinning the propeller and a smaller one at the rear to drive accessories. The engine is still far lighter than a direct drive piston of similar power. Rotax aircraft engines are all geared, I believe, and they seem quite successful in their < 140 hp class. To add to the speculative chat of this thread — How about visualizing a Rotax of around 200 hp powering a “Super J” Mooney? It can burn car gasoline, placing the plane at a strong competitive advantage when 100LL is no longer available.

    There are apps available to evaluate the various nav satellite systems.

    When GPS constellation is down...use the iPad which also receives GLONASS.

    What’s a “radio station?” Old Birdmen (circa Ernie Gann & his contemporaries) would tune the ADF receiver to a clear channel & they claimed the needle would point towards lightning strikes.

    True enough, so the comparison suggests that of the total 75K GA installations not all are piston, and there are about 140K piston GA, so our Piston GA compliance is < 50%, most likely. SouthWest Airlines is at 95%, as noted above. Airlines seem to be doing a lot better than GA.

    Here’s the count as of 1 December 2019 I checked one of the majors: “As of September 30, 2019, Southwest had 752 Boeing 737 aircraft in its fleet”. Ref: SW Fleet So SW has 715 out of 752 compliant with a month to go. Close....

    The FAA estimates of GA piston engine fleet are in FLEET. They show 141,000 GA piston fixed wing in 2015. As of December 1, 2019 the ADS-B compliance figures are, for all GA ( not just piston) but not including air carrier: So these data indicate the USA GA Piston fleet is about 50% compliant.

    I looked at Barons and Cessna 340s but bought a single turboprop. You only need one good engine. IMO. But this thread is about the T210: I got a lot of useful business and personal travel out of mine between 1999 and 2006.

    I used to plan on 175 KTAS in the mid-teens in my stock T210N. I didn’t take it above FL180. Range of 700-800 nmi is realistic. Many T210 have either the Flint wingtip tanks or the O&N baggage compartment tank. Or both, upping the total fuel to around 150 gallons. With 90 gallons:

    Really? Not even the retractable gear mod? Impressive.

    Mooneyspace nautical miles may be shorter than standard.

    The T210N I owned was a great hauler: Full fuel AND over 900 pounds in the cabin. Fast enough, very comfortable, and you sit in the shade all summer.

    To a “pop-up” request I suspect that controllers will issue “remain clear” advisories to non-compliant aircraft after January 1.

    Check out the Cafe Foundation Mooney for a stretch goal. Yes, it was an E model, not a C. But the airframe and cooling mods were applicable to any short-body M20. The developers were fond of touting efficiency and not speed: The claim was it would do 160 KTAS on 6.7 GPH I opine the upper limit of an “unlimited mod cost” M20C cruise speed is around 170 KTAS / 9 GPH / 6,000’. For $250K I’ll prove it....
  17. Jerry 5TJ
    The planned flight was short so they didn’t need to carry all 2700 pounds of fuel.

    The average avionics shop does not have a full Mode S + UAT test suite & so the airborne test is a good post-installation test to verify the configuration as well as the hardware.

    The KI-525A has become inexpensive as many reach the market now as we upgrade. A purchase of a used unit may be cheaper than an overhaul.

    Or as the salesman said of his cheapest motorcycle helmet, “A $10 helmet for a $10 skull.”

    The turbine in a JetProp PA46-350 Piper Mirage replaces a turbocharged Lycoming piston. The new turbine engine is not really an order of magnitude more: A PT6A-35 is “only” 2-3 times higher in cost than a new Lycoming TIO-540-AE2A. (The latter is now a staggering $196,000 outright from AirPower) AirPower List The PT6A also weighs much less, is considerably more reliable and effortlessly puts out twice the shaft horsepower compared to the piston. Hard to compare the two technologies except on price as in operation and performance they are so different.

    Well, may I suggest go fly at night out of Reno or Las Vegas or Albuquerque.
  23. Jerry 5TJ
    Perhaps a take-away is: Don't fly VFR at night in the mountains. And watch the terrain page, even IFR.
