First of all... many places , especially in Texas use the LSA aircraft for their programs. The are WAY more fuel efficient, AND can be used all the way up in traning. You can do Private Pilot training in a light sport airplane, same with commercial. I know a student that took his Commercial license in a LSA because the cessnas were expensive. Yes.. he did the Multi Commercial, and the Multi was his complex, and did the rest of the single engine requirements for his ASEL/AMEL commercial in the LSA.
I used to give LSA a bad rap as well.. But been instructing it for along time at a major school and we use them all the time!
I know for a fact that colleges like the above post "Stay away from LSA" mainly because they DO NOT UNDERSTAND LSA and what it can do. You can get your LSA license, and then use those hours to count towards your private, because esentailly it is the same thing. The only thing is no night flying and two you cant fly more than 50miles away from your home base. However, yes, MOST collegiate level programs already have a fleet of metal and they dont want to either buy more planes or can't afford anything else at the moment. LSAs are on the rise, thats a fact, and the training places are on the rise as well. So far LSA has taken off more than the Recreational Program did.
Mainly long story- to answer your question- as the above post.-- Yes. most Collegiate places don't want to mess with it cause they think its a waste, yet, it could be beneficial to their program as a "starter", but they just dont understand LSA, so they discredit it and move on.
