Prop on the lock

[divinglyc]

Hi! During the engine start procedure, we have to check that the prop is on the lock.

But, how do we know if the prop is already on the lock?

Thanks a lot!

Before the engine starts, you check visually  (pilots lean over and look out the window)....and make sure the blades are "flat". (rather than feathered)

After engine start...the real MU-2 POH says that if you move the power levers forward past flight idle and you do not see an increase in torque or fuel flow, then the props are on the locks.  In this case... its basically like finding out your car is in neutral when you give it gas and it doesn't go .
