Having recently completed training, I can sum it up as:
a.) possibly one of the most challenging training programs in the industry. It’s a rapid grind.
b.) very accommodating. From the people in crew training admin to the instructors themselves, the dedication and willingness to make it as painless as possible, is clearly a priority.
To sum it up. Anyone with a good attitude and what it takes to be a pilot, will successfully complete the program. It’s pretty apparent that the whole thing is designed for students in the mid 20’s to mid 30’s with 2-4 years of past airline experience.
Yes, too much experience creates additional challenges.
