Although ATP is geared more toward an airline career path, it is just as
good for corporate or air ambulance jobs. If you plan on attending ATP I
would stick it out to the end and get your CFI certs and teach. Teaching
reinforces what you’ve learned and builds a solid foundation that will stay
with you a lot longer than if you were to skip straight to a small
Flying for a corporation will take time. A typical route would be to start
out right seat and then working your way over into the left seat. Every
corporate pilot job will require different amounts of time until becoming
eligible to upgrade to Captain.
As for air ambulance, those jobs typically require anywhere from 3000-5000
hours total time with about 500-1000 hours turbine pic.
So, it’s your choice. You could build time at a airline first, and see how
you like it and then switch to corporate or air ambulance. Or you could
build your time sitting right seat in a Citation as a corporate pilot. But
I would definitely instruct for at least a year.
May I ask why you’re interested in corporate and air ambulance? I’m curious
because I thought about those two options as well, but I’m actually very
happy I chose the airline route.
