I totally agree with The Beater on this, but :-
Holding an ATPL (H) IR with two crew, twin engine, varied experience (offshore, VIP, SAR, Air Ambulance, etc) plus 2500 or more hours will help to open the doors. Of course there is then the argument about how is the low time CPL to gain such experience?
Why would you need to 'open doors' if you had that sort of experience? Surely you'd be in a job somewhere if you did? Or maybe not???
Mind you, saying that, I know a few people
with thousands of hours, ATPL's IR's, and there just aren't jobs for them and they are presently looking.
The market isn't good for helicopter pilots right now, even the experienced ones.
