Good 141 flight schools
I worked at
MAPD and
FlightSafety Academy and would recommend both. Both train you for your ratings but have different approaches.
MAPD is unique because you can interview at Mesa Airlines for an FO position upon graduation. It is not as easy as I just wrote it, though; a lot will be expected of you, demands will be made of you, and you will work hard. MAPD trains its students
from the very first day of training to be airline pilots, as compared to most other schools which provide a standard Commercial-Instrument course. An A.S. degree in Aviation Technology from (fully-accredited) San Juan College is part of the deal - no exceptions. MAPD is an eighteen-month course. It does not offer a CFI program - which is understandable because your first job after graduation would, hopefully, be Mesa Airlines!
FlightSafety in Vero Beach exemplifies the standard and standardized Part 141 flight school. It has been around for forty years and was first known an initial training provider for Swissair and other foreign airlines. Ground school is adequate and flight training is excellent. FlightSafety does a great job emphasizing procedures and standardization, which will help you in your first advanced professional flying jobs. FSI is the only school I know that includes aerobatic and unusual attitudes training as part of the flight course. This, in and of itself, is good training because of the confidence you'll gain in dealing with upsets and unusual attitudes. The equipment is extremely well maintained, the facilities are excellent, and the people who are now in charge of the place are first class. FSI students who earn their CFIs at the school can work there after graduation - though there may be a long waiting list right now. FlightSafety carries great name recognition in the industry. FSI is expensive, but I feel you get value for your expenditure. Finally, as opposed to MAPD, FSI is about an eight-to-nine-month course and there is no degree.
The most important thing you can do before choosing a school is to visit it, and try to speak to people other than those the "career consultants" (salespeople) provide you. I understand that MAPD will provide non-rev travel to Farmington from any point in the Mesa system.
Hope that helps some more. Good luck with your choice of flight school.
