    Ethiopia publishes interim MAX 8 crash report

    Except for the autopilot wasn't the problem. The MCAS, which is literally a software program to drive the electric trim, is independent of the autopilot. The airplane was fighting with them while the autopilot was off. All they had to do was turn the electric trim off and FLY THE PLANE, which...

    First long cross country and need opinion

    X2 on the mountain turbulence. Leeward side of the mountains can get really, really rough. Look at the pressure difference between the windward side and the leeward side of the mountains. Every 10th of an inch of Mercury roughly equals 10 knots of wind. I would not be too excited about going...

    Final call from the "IRS"

    Have fun with them next time. This is the call that said my social security number had been hacked and suspended I due too suspected criminal activity. When I got that call, he asked me if I had ever been in Texas. Yes, I travel to Texas quite often. Oh we found a car abandoned with blood...

    Airplane engines vs farm tractor engines

    Quite frankly, The reason our engines are archaic is the FAA. Add to that the litigious society that we live in, and you just have a recipe for nothing new in certified aviation. There are quite a few new and innovative designs out there in the experimental world, that we'll probably never see...

    Airplane engines vs farm tractor engines

    Truthfully I think it comes down to oil. These are essentially muscle car engines only in the fact that they have flat tappets. Back in the day, when flat tappet engines were the norm, you had zinc in the oil. The zinc would put itself into the microscopic pits on the camshaft and essentially...

    Airplane engines vs farm tractor engines

    I think he was referring to the internals, which should not be drastically different.

    Shock Cooling a myth?

    Loved the PA-31! Ahhh... Memories of Airpac, trying to kill myself in the weather over the mountains every night, for $8.50/hr The things we do (did) for flight time.

    Shock Cooling a myth?

    I will grant you that, but my question comes in the fact that CHT doesn't really change. Most airplanes, even with the turbo, easily sit on the 350 to 400 range. Is it possible, even in the flight levels, to be able to cool the cylinders faster than the 50° per minute? Does it cool off...

    Run-up at 1700 vs. 2000rpm

    Doing an idle mag check Will yield the same results as doing it at 1700 or 2000. You're not putting enough stress on the engine really truly get an idea of the ignition health. Mag xhecks should be done in the air, as close to lop as you can get. This will give you the true health of your...

    Why would a turbo be different? Sent from my Pixel 2 XL using Tapatalk
