Poll: stall speed in a jet at cruise altitude

Two words: Reynolds number.

I'll go ahead and put in a plug for an awesome book - Aerodynamics for Naval Aviators.

No no no. :D

A combination of altitude and airspeed from which it would be impossible to successfully complete an autorotation in the event of an engine failure.

Ahh... Too much vertical inertia to spool up the rotor enough to brake the descent properly. I get it.

Note: I was never a helo pilot, so my helicopter flight theory is all patchwork from picking MTP & IP brains, etc.

I did however have to yell at one IP to tell him how to fly.

"Sir, 120% RPM-R is NOT NORMAL. Red chiclets are not okay!"
>sigh< Pesky warrant officers.

:D

Isn't that what they call a helicopter cockpit.

Reminds me of that line from Call of Duty 4.

"If the wings are moving faster than the fuselage, it's probably a helicopter, and therefore, unsafe."

Helicopters don't actually fly. They just beat the air into submission.

LMAO--- I'm using that one. Hilarious!!!

Not impossible, Sir, just unlikely for the normal school trained individul. With practice, a helicopter will autorotate from any altitude at a hover.

Take the standard 3-foot hovering auto, and increase it one foot at a time, and you'll be doing it from a hundred feet before you know it.
 
To the best of my fading memory, the most dangerous part of the chart was during high-speed, low-level flight.

And a 100 foot hovering auto in a Jet Ranger is one thing. A 100 foot hovering auto in a Chinook is another. ;) Thank god for that second engine!
