GLIDERBOY
Double Assy.... as an ex instructor who taught your pilots course, I am afraid I will have to ask you to REMAIN STANDING....the PC9 is 1100HP derated to 950!!
There is a slight murmur from the students assembled, the instructors down the back look at the quizo, and a few cough and shuffle.
The CFI stands and addresses gliderboy. "Would you like to try that again?"
"Sir?"
"Yes Gliderboy, the PT6A is infact 1150 SHP, derated to 950 SHP at Max and 900SHP at MCP" Remain standing!
