Powerback what do you actually mean by Powerback eal401?
Because there have been 2 differeing answers allready described here. Power Off Landing and Reversing Engines on the Ground to manuovre and taxi. Which is it?
I can assume a ATR can be reversed also a Dash8 but one needs to carefull due to the Nosewheel Wiring being affected if the Dash Nosewheel goes thru the 180DEG mark rapidly.
As for B1900 well I have seen people do it in King Airs but its highly not recommended due to F.O.D. Foreign Object Damage of the Engines and Props and high I.T.T.s . In general a High Wing mount Turbo Prop shouldnt have a Problem, but I would never myself attempt it in a B1900. Twin otter is ok. Must have good ground Marshallers or know whats behind you.
