Actually what I meant was, if engine surges / stalls with a lot of over-temp n bangs ( which are a possibility in ATR engines -pw127e, besides even having HANDLING BLEED VALVE -to cater for extra air for surging ). N the power lever setting at which things go normal is at flight idle setting-that increases drag. So just after take-off is it advisable to feather the engine to avoid drag n sort out the issue at higher altitude?
Your QRH or FCOM certainly has procedures for that dramatic an event. What does it say?!?
