    GA transportation of (personal) firearms and ammo

    Treat them just like the full sized tube of toothpaste and water bottles you bring aboard. Draconian TSA rules do not apply to Part 91.

    All about the perception of equality and justice.

    Can I use a 20a toggle switch?

    Tom, you're right. The Avionics Switch in the OFF position will allow two paths to the Primary Bus. The first will be directly from the External Source and whatever the shunt drops, and the second will be through the diode and Avionics Switch. So Kirchhoff’s rule of parallel resistance...

    A brand new plane still not better than a 50+ year old Cessna 182

    50 years ago the best tech was added to new planes, same as today. And at the same price - whatever the market will bear. So that's a wash.

    Cheapest way to build retract time

    Gotcha. I had thought I had seen a few in pretty good shape for $69k recently but I guess they got scooped up.

    Cheapest way to build retract time

    I've tried to find the specs on the Cutlass and as best as I can tell, it grosses at 2540 and weighs 1691 empty, leaving 759 available for fuel, bags, and humans. If these numbers are correct, with 40 gallons of gas, it'll only carry the front 400 pounds and 40 pounds of luggage.

    GPS backup

    For the same reason Garmin, Avidyne, and others are able to sell products. Convenience.

    GPS backup

    The entire Google Earth data on an iOS or Android device and a special onboard camera to match what is under the plane. You'll know Lat Lon, heading/track, groundspeed, AGL and MSL, and since Earth knows airports, the destination's fix. Minimal cost and 100% onboard like an INS, dependent on...

    Altitude and the Aerocruze 100 (TruTrak) Autopilot

    The 10.3 update enabled Enroute VNAV, but you are right. The initial release, 10.3.0.2 had a bug or two, and 10.3.1.2 fixed them within a couple of weeks, and has been solid at least for me for a year. Here's the Applicable-to-Enroute-VNAV release notes:

    Voepass Flight 2283, a large passenger plane, crashes in Vinhedo, Brazil

    The F-4 was about as close to zero as any plane. I think Rutan was able to recover two (without popping the chute) out of almost 1,000 that he put into flat spins.

    Voepass Flight 2283, a large passenger plane, crashes in Vinhedo, Brazil

    Just a guess - An uncoordinated stall with improper recovery procedures.

    Altitude and the Aerocruze 100 (TruTrak) Autopilot

    Yes, I know this is old, but the latest Avidyne firmware update gives us enroute VNAV. The autopilot will fly an Enroute VNAV profile when all of the following are true: • The Aerocruze is in GPSS Mode and ALT HOLD or VS 0 mode • The upcoming IFD540 FMS waypoint contains an altitude • The...

    Can I use a 20a toggle switch?

    I've got a fairly low avionics current draw and monitor my current closely. It will sometimes go as high as 20 amps. When I did what you are looking to do, I felt more comfortable with a 40 amp switch. To tie the two busses together, I used a SPST Longacre 45423, 40 amp toggle and protected...

    Aerocruze 100 'Sensor Error' message

    It actually knows pitch and roll attitude too, Darryl. Take the head out of the mount and move it in roll or pitch, and flight control movement is immediate and fast. Makes sense, because most every autopilot monitors attitude and corrects for it immediately no matter what mode you're in (Alt...

    Blue Angels IMAX

    I saw it at the Pensacola IMAX 5/18 and really enjoyed it, but I too was disappointed with the cinematography. In 2005 I saw "Fighter Pilot: Operation Red Flag" and it was glorious.

    Extremely noticeable and makes a difference on my Cardinal RG.

    Dynon HDX & IFD540 in Cherokee 235

    Sounds great. Can you think of anything the Dynon certificated autopilot can do that the Trio (once upgraded) can't?

    Dynon HDX & IFD540 in Cherokee 235

    I am very interested in this. First I've heard of it. Can you elaborate on what features it'll have? This could be great news for those of us who have installed the Dynon but are in Limbo for their autopilot.

    Dynon HDX & IFD540 in Cherokee 235

    Appreciate the compliment Alien. Got em on Amazon. Actually ordered a single and double, and I keep a single on the door just forward of the door opening handle. I use that one for a pen, and the one on the panel is handy for specs, sunglasses, etc., or pens, as you can see. I cut the...
