A question for an ATR pilot.
Let us assume that, for what ever reason, there was a loss of power on left engine, what kind of performance is possible assuming the auto feather is successful?
If the auto feather malfunctions, and therefore a windmilling prop condition exists, the performance is significantly degraded until manual intervention occurs in a timely manner.
This will be practiced during LPC/OPC in the simulator. How much more difficult is it to control and survive?
Loss of airspeed is always the final critical factor in this type of accident.
Remember the accident with the Airtours crew being flown GLA-ABZ in a Cessna twin?. This of course was not a performance A machine
