Propulsion Update by P&WC

Latest update from Pratt & Whitney Canada presented during the ATR Flight Safety Conference.

Q&A:

We had odor events, PWC recommend 2 min “at GI” to cool before shutdown. And it’s different than ATR FCOM’s 2 minutes “below FI”. What’s ATR perspective?

The ATR FCOM will be modified to be in line with PWC recommendations.
Can we have a safety instruction video for ground handling from ATR?

ATR does not intend to produce this video in the near future.
Is it important to record the time that the engine runs on hotel mode?

It is difficult for the airline to do that monitoring. From an equipment reliability standpoint, please refer to the Service Information Letter 145 recommending reporting events in hotel mode and in particular the prop brake.
