Update on PC12 inflight breakup in FL

TBF, I remember once having the autopilot fail in such a way that the master caution blared constantly and the only way to make it shut up and for the autopilot to work was to run the test. Which is obviously no excuse for not flying the airplane, but it was extremely irritating, particularly because there was an attractive female physician riding up front with me. Damned autopilot ruined my retirement plan.

In the NG, if the A/P gets kicked off line by something other than pilot input, the very loud A/P disconnect keeps going off until you hit the Big Red Button on the yoke. It was a pretty exciting period of hitting every button in the cockpit the first time that happened to me. Thankfully the A/P in the NG was 100 times better than the one in the legacy airplane.
 
In the /47 Vy was 120, decreasing to 115, and then 110 as you climbed according to the POH - I usually climbed at 120KIAS pretty religiously because it meant you could always turn around and glide back to where you came from.

You'd climb at 120 all the way to cruise?

That's how the last one was for me except replace attractive female physician with male ridealong intern. And it's not a little "Ding" like the master caution, it's basically the same as the god almighty wail that is the gear horn.
 
Yeah it wasn't the lovely little chime of the uh whatever acronym that particular airplane uses for the warning panel (CAWS, is that right?). It was the sound of "the pilot screwed up and we're all about to die".

In the Pilatus, pretty much, yep. That is to say unless I was in icing conditions, then with PIM on, I'd be around what that speed was supposed to be (I can't remember the speed, and something about 8° lower max AoA or something, now that I'm in a different airplane - 140ish sounds about right). Technically speaking, Vy is the most efficient way to climb for a given unit of time, and it meant that I could turn back around and land back at the airport I left (99% of the time) which was a highly useful thing flying around Alaska.

I tried climbing out at 140, or 150 and comparing fuel burns with similar loads, you'd save almost 100 to 200lbs on a trip by climbing out at Vy as opposed to 140 to 150 ish. Your climb rate at 140kts just drops off precipitously after about FL230 to FL250 somewhere in there.

Profile? What is this witchcraft?

It's been a while, but I seem to remember trying to keep it above 150 indicated at all times (aside from takeoff and landing, obviously). I think that was fairly conservative, but 109? Yikes.

@Boris Badenov is just being hyperbolic. I heard Badenov can land a Pilatus out of 45 knot approach without even scratching the treads.

Food for thought regarding the lack of training of the pilot. Two CRJ pilots crashed a perfectly good airplane a few years back due to a lack of understandi


159 knots. Duh.

Your post got cut off but you're not referring to Pinnacle flight are you? If so, that flight has NO place nor is there a parallel to this one; unless your comparison is stupid pilots doing stupid things. Then, there might be a common.......

I did a Vy climb out once on a RVSM test flight, and the deck angle was much too

Huh, I remember starting that post, then deciding against it....I guess it somehow posted anyway....

Ha, this reply had the same issue!!! I had started to reply to PPRag's post, and didn't finish it, but when I went to reply to what you posted, it included the unfinished post from earlier. Something very wacky with this message board.....
