Two of the approved programs are 4 year degree programs at Embry Riddle. They cost a whole lot more than 5K. The one stand alone program is run by Sporty's, the same folks that send you a catalog every few months. The people saying it would cost 15K-20K didn't have a clue. Figure an instructor is getting 200 a day for the classroom so 800. Bump it up some for the sim day and call it 1500 for the week. I'll bet the sim, an old DC-9, is costing them $500 an hour. So 6500 to run the class. Two students will pay 9K, so you have 2500 to pay the light bill for the room and profit.
