Thanks for the info guys.
For better or for worse, the ground course I did placed a lot of emphasis on rote learning numbers. I have nearly every number in the POH comitted to memory (What temp does the CABIN AIR DUCT O'HEAT anunciator come on at ?) but perhaps it was assumed that I knew the fundamentals.
A very experienced pilot once told me "You dont know what you dont know" - I think I am in that position.
Sheepguts - Its the -112 in the F406
WRT my homework - You wouldnt believe this sir but you see I was looking after a friends dog.... I only went out for five minutes..... !
The power leaver pedestal is marked in three ranges. Flight, Ground Idle, reverse. With a gate between flight and ground idle. Very little reference to Beta in the POH.
One mention in the definitions part of section 1 "BETA MODE - Engine operational mode in which propeller blade pitch is controlled by the cockpit power lever. Ground ops only"
Then later on that "To acomplish reverse pitch, the power levers are retarded beyond idle, over the gate and into the BETA position"
From the limitations section of the POH, prop blade angle at 30" station:
* Feathered = 85.5 degrees
* Low pitch = 18.5 degrees
* Full reverse = -13.5 degrees
and engine limits:
* Idle = 685ITT
* Max reverse = 1382 ft-lbs, 725ITT, 101.6%Ng
Was that what you were after sheepguts ??
Regarding Flat/De rating - A lot of people have told me that this engine is DErated, however the POH says that its flat rated to 500SHP. Ive also heard the phrase "Bulletproof" mentioned in close proximity to "derated" (should I be worried??). Is there a laymans definition of derated that is perhaps confusing me ?
Thanks again for your help people - If youve got any more useful comments please keep them coming - Im keen to find out all the things I dont know !
