A major part of fighter pilot training is learning the handling of the aircraft itself. On the other hand, automatic controls on modern fighter jets take away a lot of the pain and hassle. I am curious about the extent to which such ease of use plays a role in choosing the Lead In Fighter Trainer (LIFT) platform for an airforce.
Usually, it is assumed that the manufacturer supplying fighter jets will also supply the LIFT platform. But an airforce could buy jets from multiple vendors. It would be extremely cost ineffective to buy a different LIFT platform for each type of fighter jet. So airforces should try to standardize the LIFT platform they use.
Assume an airforce buys both single and twin engine fighter jets, from two different manufacturers. Neither aircraft has a twin seater version, so the first time pilots fly in them, they don't have an instructor sitting behind them giving instructions. Obviously, the aerodynamics and general handling of a twin engine fighter jet ought to be quite different from a single engine fighter jet. Now in making a decision on standardizing the LIFT platform, would this airforce take into account the presence of both single and twin engine fighter jets in its inventory? Would it procure two different LIFT platforms, one for training pilots towards single engine fighters, the other for training pilots towards twin engine fighters? Or does it make any practical sense for the airforce to choose only a single engine LIFT platform, or only a twin engine LIFT platform? What would be the pros and cons of such a decision?
