This doesn’t actually hold up to reality because 737 variants are not interchangeable. Gauges may be in the same place but have a different appearance. There have been accidents directly caused by differences between variants. (Shutting down the wrong engine because the air conditioning now used bleed air from both engines, not just the right one.)
My understanding is difference training is required to certify a pilot for a specific variant.
- selectodude 4y agoThe 737 is a single type rating. They are interchangeable. That was the whole idea behind Boeing's MCAS system - the 737-MAX didn't fly the same due to the engines being pulled further forward on the wing, so they made a piece of software that made the airplane feel the same as the 737NG.
- kayodelycaon 4y agoYou can’t fly an 737-200 for 3 years and then jump into a 737 NG without difference training. You won’t know how to work the flight management systems. They are the same type, so you don’t need to re-qualify for the type. But you need to do training to move between variants of a type. It’s just a lot less training.
