Seminole Gear

[ShyFlyGuy]

WOW, that's pretty in-depth systems knowledge for a Seminole. Who wants you to know that, school or examiner? I'd hate to see the explanation for a constant-speed propeller.

Shouldn't "electrically powered hydraulic pump with mechanical gear downlocks, and is held up by hydraulic pressure" along with an explanation of the emergency gear extention procedure and theory be sufficient to test your understanding of the Piper retractable gear system? After all, Arrow = Seminole = Saratoga = Seneca.

BoilerUP, you wouldn't understand. It's a 141 thing. Enough is never enough. We know EVERYTHING about our (simple) aircraft in preperation for knowing a little about EVERYTHING about the (complex) aircraft we're gonna fly. It's usually a sign of a program directed toward the airlines.

I think you should know as much as you can know. It doesn't hurt.

Downlock hook on the nose gear.

Pump is turned off by the pressure switch - 1800 psi +/- 100.
The uplimit switches turn off the "gear unsafe" light.

Trust me... that's your answer.

"In preparation for the airlines"???

Easy there, fella. Let's not get into the "my training is better than yours" stuff. It is the pilot, not the training that determines who cuts it.

It certainly is. I just got back from the airport where I looked at the downlock hooks and asked a mechanic about the switches, who confirmed what you said.
