"Practice" Emergency Descent

Props forward with gear down in the 1900C with a full load (at 16000-ish) will give you a peg the needle hanging from the straps descent. That was pretty fun, and i've done that a few times.

Did one in the Encore during my training. I found it interesting that the VSI pegs at -9999. My guess is that we were doing something like 12,000-13,000 fpm at the highest. FL360 to 4000 in 4.5 minutes. I was too intimidated by the nose down attitude that I didn't keep it at Mmo, so we probably could've done better than that.

Just curious as to why you were intimidated?

In the SAAB, going into reverse (or was it ground-idle?) in-flight was prohibited after an accident occured due to a pilot doing this. They even installed a lock on the power lever to prevent moving the control to reverse (ground-idle?) until weight-on-wheels was detected.

You talking the American Eagle in '94 in Louisiana?

WHILE DESCENDING FOR LANDING AT BATON ROUGE, THE CAPTAIN ACTIVELY MOVED THE POWER LEVERS FROM THE FLIGHT IDLE GATE INTO THE BETA RANGE FOR UNDETERMINED REASONS. THE PROPELLERS AND ENGINES EXPERIENCED EXTREME OVERSPEED, NECESSITATING A POWER-OFF EMERGENCY LANDING AT NIGHT AND THE AIRPLANE RAN OFF THE END OF A 5,000-FT RUNWAY. ALTHOUGH THE DESIGN AND CERTIFICATION OF THE POWER LEVERS MET EXISTING REQUIREMENTS, THOSE REQUIREMENTS WERE INADEQUATE BECAUSE THEY PERMITTED A DESIGN THAT DID NOT PREVENT MOVEMENT INTO THE BETA RANGE IN FLIGHT. THE AIRFRAME & ENGINE INDUSTRY, THE FAA, AND THE CERTIFICATION AUTHORITIES FROM OTHER COUNTRIES WERE SLOW IN REACTING TO SEVERAL PREVIOUS IN-FLIGHT BETA OCCURRENCES THAT LED TO SERIOUS INCIDENTS AND ACCIDENTS.

Probable Cause:

THE CAPTAIN'S MOVEMENT OF THE POWER LEVERS BELOW FLIGHT IDLE IN FLIGHT, THE INADEQUATE CERTIFICATION REQUIREMENTS AND CONSEQUENT DESIGN OF THE AIRPLANE'S POWER LEVERS THAT PERMITTED THEM TO BE MOVED BELOW THE FLIGHT IDLE POSITION INTO THE BETA RANGE, EITHER INTENTIONALLY OR INADVERTENTLY, WHILE IN FLIGHT, AND THE INADEQUATE ACTION TAKEN TO REQUIRE A POSITIVE MEANS TO PREVENT BETA OPERATION ON AIRPLANES FOR WHICH SUCH OPERATION IS PROHIBITED.

I was curious about this as well, but I bet he won't answer...he just does drivebys without regard to facts, and moves on down the road...:dunno:

because theres no way to drop a lear at 12,000 fpm without exceeding Vne. Even if it is possible, it's not the smartest thing to be admitting on a public forum.

How much Lear time do you have?
And there is no Vne on a Lear.
Guess you didn't learn that while you were a freight dawg for a week.
 
My point is that even if it can be done without going past Vne, it's still not part of any normal operating procedure and it shows a disregard for the rules. If an interviewer were ever to read this thread, mickcweb would have some explaining to do.
 
Mike told me about his 1/1 descent into ATL in the 35 about a year before I recommended him to be hired at my company. He got hired, with no explaining. Actually, his experience with "flying outside the box" got him the job.

So operating an aircraft completely within its limitations to maximize it's operational capabilities is now somehow against some rule somewhere?

Got a number on that rule I can look at?

Safety doesn't work like that. Just because it's legal DOESN'T mean it's safe. If you want to argue that descending 12000 fpm is safe, then just wow... Thats all I can say...
 
My vote is "safe"

But then again, I've done it before.

I've also flown a jet around at stick shaker for 10 minutes. I've stalled a jet; a full aerodynamic stall, not the stick pusher stall they teach at the sim houses. I've climbed a jet at 5 knots above stick shaker. I've depressurized a jet at FL310.

You know what. It made me a better pilot by doing it, and the next chance I have, I'll do it again.

It's not your normal regime of flight, but I was with an experienced test pilot and it was completely safe.
