autofeather question
NSTB ASRS REPORT NO 823457 of Feb 2009 involving an ATR72 reads as follows.
During takeoff, the #2 propeller went into feather. I aborted the takeoff and returned to the ramp. Maintenance told me to do a run-up with the Automatic takeoff Power Control System off, because he suspected that it was sending a wrong electronic signal. I did the run-up with the Automatic Takeoff Power Control System on and off and both engines were operating normally. I concluded that since the aircraft's electrical system had been reset, the situation was corrected. I discussed the situation with the First Officer and we both felt that it was safe to fly.
