I'm sorry but 42 hours is ridiculous and IS an absolute scam. You do realise what you are doing and why you are doing it on a Seminole? All you are doing is a conversion onto the aircraft, its called your initial twin conversion. Thereafter you want to do a few hours practicing IF on it for your test. Probably 2 or 3 ILS's / VOR approaches and then upper air work. The simulator is used to get your procedures and calls correctly, so use it a lot! To be charged 42 hours is going to be over R100 000! You can get a 737 or A320 rating and not do anywhere near that amount of hours! Why not go around and ask the pilots who have finished their comm / atp etc and ask how many hours they did on a twin when they were training (and not guys from the same school who finished 2 weeks ago!) I'm telling you from my experience I didn't even get to 20 hours on a Seneca, and as far as I know my old ATP is worth the same as a new ATP... ohh and it took 30min to fly to an airport with a VOR / ILS to practice!
