Is FLEX/ATM takeoff a thing for SETP aircraft?

Featured Replies

I know Flex  temperature aka Assumed Temperature is a ting on multi-engine Turboprop, but what about Single Engine Turboprop then?

Specifically for PC12 I'm flying in P3D, but also for similair one like TBM900 etc...

From it's POH's performance charts, it's easy to workout just as if it's a MET or MEJ, and I have done it for quite a while without thinking too hard and works without problem in the sim

But when I starting to practice the "impossible turn" for PC12,  I just relized it's different beasts from multi-engine jets I used to work with, and wonder if FLEX/ATM legal, or pratical to do so in realword, thanks.

What is that?

You're referring to taking off with less than full power correct? What I call a reduced power TO. As you stated, if it's in the TO power charts then it's an option to use if you meet the specified conditions.

I still don't know what you mean by "impossible turn"?

FLEX temp or ATM means use less than full power, but it's not a seperated TO power chart, it's using the same charts and table but use a assumed higher than actual outside temperature, it's common on MEJ or MET, but I'm not sure on SET.

"impossible turn" means pilot try to turn over 180degree (270+90), after the only engine failed shortly after takeoff. It's more recomnanded to force land ahead outside and damage your aircraft rather than killing yourself during the turning back, thus named "impossible".
