Teaching "type" or teaching "generic" is something I have wondered about for many years.
With regard to one of Centaurus's posts - I was riding alongside a UK flight instructor - who had 700 hours of "dual given"..........all in Cessna 150/152/172.
We were in a Piper Arrow and, sure enough, he said "undercarriage down and locked" - and did NOTHING. When I asked about it, he said he had been doing the call - with no actions - for many years....so he kept doing it!!
