The new trainers are a much better match to the new aircraft. The GA fleet is being updated quite fast with new glass ships and VLA’s replacing the spam can fleet. The Strip I fly from is made up almost entirely of modern PFA kit, and vintage (pre 1950) kit. There are only two “traditional” aircraft out of 20.
If you want to attract new pilots you need to get them out of their BMWs into a modern machine, not a smelly, tatty, 40 year old pile of old junk.
