Indeed it is. MATOW is 11,850lbs. It's nothing special... The 550/S550 and the 560 are a bit bigger.

The CH-47D has a 50,000 lb MTOW, but as hard as I tried I couldn't stall the thing.
(For the picky, yes you can stall a helicopter, just in a much different way.)
Retreating blade stall? I'll take my straight wing stall over that everyday of the week lol.

Tries to keep it fun.
Lear 35 for me as well, it just powers right out of the stall. Never took it past shaker though. You don't even have to let go of that much back pressure. The engines spool up pretty quickly.

B747.
She's a real bitch to stall. Something like 40 degrees nose up with 65% N2.

What a tank of a airplane. They made good crap back in the day.anic:
No stick shakers or warning in the might O. Just buffet. Can actually fly out of a stall, but if you have an assymetric spool up, you are below VMC and this can happen.....

On July 22, a Navy P-3C conducted a simulated engine fire and shut down one of the port engines. Shortly thereafter, the flight crew noticed engine fluctuations in the second engine and shut it down without trying to re-start the first. The plane violently rolled and began a spiraling nose dive at 290 knots.
The pilots allowed the starboard engines to remain at maximum power in spite of NATOPS' requirement to go to "flight idle." A counterclockwise rotation was driven by the stall and the yaw produced by the two engines at maximum power.
The plane was pulling between 5 and 7 Gs and did five spin rotations form 5500 feet before the flight crew was able to restart the first engine and recover at bteween 50 and 100 feet above the deck.
The plane returned to Whidbey without further incident however the aircraft was essentially destroyed -- the fuel tank was ripped open, several panels were bent or buckled, and 45 consecutive rivets ripped out as the starboard wing skin peeled away

All the responsibility none of the authority
Huh....You learn something everyday. :yup::yup:

Do you guys practice them in the sim?
Power on stalls in the P-3 are a big no no. Every 1000 SHP on all four engines lowers stall by 8 knots. Theoretical at low weight we could be stalling with 3000 SHP at 58 knots dirty!

Yeah, we practice them in the sim.
To the first indication, and then you just power up, try to wrangle all the power in a sensible manner.
Like everything else, clean stalls are power off, more or less
Takeoff stalls in a Takeoff flap config and in a bank
Landing stalls, dirty with landing powerset.
The only thing I've found with the whale is the time between cobbing the power, with no reaction from the motors feels like forever. Then it's "Hold the hell on" because it seems like all 250,000 lbs of thrust shows up in a rapid manner once they spool.

19000 - 20000' feet???? They took it up to class A airspace and did stalls??? Seems a bit high to me.
edit: Maybe this happened doing some other test and they ended up in one. Maybe I'm just being overly skeptical, but that sounds a bit off to me... *shrugs*

No pasa nada.
Like I said, heresay, but a cool story. Also, I think you can get a waiver to go VFR in Class A in certain areas for flight testing, so that's not outside the realm of possibility either.

Can't remember if we did turning stalls but we did do FULL stalls in the 737-300 during a flight test. Full aft stick and letting the nose fall through.. like a big Cessna.
First a buzz, then the shaker and then a hard burble followed by the break. Not a big deal.

Wow... how much altitude did it take to recover?

Not a lot. We were in the teens when we did the stalls. Maybe a few hundred feet or so...300-400ft? It was back in the 80s when the airplane was new so it has been a while and I no longer have my notes.
We also did full aft stick in the Lear 31A with Pete Reynolds. Again, not a big deal with those delta fins. The nose fell through but doing them at around FL500, it did take a while. Ceiling is FL510.
Got to fly a light G-V and we did steep turns at FL510. That is one great wing.

The Flight Instructors guide allows for straight power off P-3 stall buffets. I would take instructors under training up to a full stall so they could see. Recovery was about 50 feet if you were good.
