Thank you,
I was 99% sure that is how I read it. His reasoning is that it is extended for an emergency descent so why would it differ for any other operations

the checklist reads:

But I am guessing that is for emergencies only. If Vlo could be exceeded then why would it exist?

USMC-Sgt,

It sounds like your training is coming along nicely, and more importantly is the fact that you're enjoying it. Keep up the hard work and studying and I guarantee you that it'll be worth it.

Pertaining to your question about service ceiling, you are correct. For multiengine aircraft the service ceiling is when you are able to maintain a 100 fpm climb. Another important altitude is your single engine service ceiling, and that is when you're able to maintain a 50 fpm climb while single engine.

Also, I agree with de727ups. I'm a little confused why your MEI instructor would instruct you to extend and retract the landing gear if it's above its performance limitation. You always want to double check and make sure what the gear limitation speeds are. I know for the Piper Seminole that the gear extended (Vle) and gear extension (Vlo down) are both 140 kts.

If the aircraft POH says that landing gear extension and retraction is112, and landing gear "Extended" is 140, you should stick to those numbers. The reason for this is because if you try retracting the landing gear above its max gear retraction speed you can damage the hydraulic pump due to more hydraulic pressure being exerted on the pump. This is due to the gear, particularly the nose gear being retracted faster due to the stronger relative wind at faster airspeeds.

Just to be sure you should double check to see if max gear Extension is the same as max gear Extended. If that's the case then the emergency checklist agrees with itself because you would be able to extend the gear at 140, not 112.
