212Man, that is a very good point, I probably should have thought about that myself. Still, an AW139 is a lot of helicopter for what they're doing. I assume an AS355 for instance, does not meet the requirements - twin engine does not necessarily imply that it will be able to continue flying for any length of time with fuel, passengers, and a bunch of electronics hanging off the outside.
Senior Pilot, thank you for getting my videos operational!
