757 MEL question

Just a quick question for anyone who can answer. I'm a corporate guy and was deadheading EINN to KEWR. Captain announced the APU was not available for ground power/air. Naturally I gathered it was being MEL'd. Current airplane I am on will not allow the APU to be MEL's for extended range ops. Wondering if this is allowed on the 757. Thanks

It varies between some carriers whether or not the APU can be deferred prior to an ocean crossing.

Delta's APU can be deferred and the aircraft restricted to 120 ETOPS, assuming the HMG works normally. I know this from experience!

Thanks for the info. On the Gulfstream we also have an HMG but still does not allow for the APU to be MEL'd

Delta however prohibits dispatch form the US outbound with the APU inop. The MEL allows operations in either direction however Delta is more restrictive. Almost all other airlines allow dispatch both ways without a APU.

All Depends

Personally, I want the APU to be operational for an ETOPS departure but that's just me.
