PT-6A Holding the prop on start up?
I have often read that it is possible to hold the propeller of a PT-6A during start up. Has anyone actually witnessed this????
I understand why it is theoretically possible, however can it actually be done for more than a couple of seconds after air starts flowing over the power turbine?
Wouldn't it cause enormous damage to the power turbine if you were trying to prevent it turning by holding the propeller when fuel is introduced?
Is this just an OWT??
