There is the multi pilot helicopter thing in the regs. Who flies multi pilots ops ? First and foremost oil & gas. Very few VIP ops maybe.
A mere mortal will not be able to self fund a type rating on a MPH, let alone 350 hours after that. With the shortage of airline pilots some helicopter guys might have gone the transit route
but there are still plenty of highly eperienced guys looking for work.
You might want to get in line and draw a number.
