Weeeellll....
As a CFI, I ask that all FIs teach the same things using the same techniques. Thus we have the Standard Closing Angle technique for visual navigation, the Point-and-Power technique for the final approach and the Constant Sight Line technique for PFLs as our standard methods.
But just occasionally the odd bit of rubbish floats along- such as DRIBL or DABL checks or whatever the bloody things purport to be. These are politely stamped on before they become established. As is the utter nonsense of mistaking 'Select, Hold, Trim' with a misunderstood 'Attitude Power Trim' concept - which all stemmed from some old Oxford ar$e many years ago who didn't really understand what CFS were driving at, hijacked a mnemonic and then misapplied it...
Style is acceptable; standards are essential.
Incidentally, I'd far sooner have an experienced PPL holder teaching at PPL level, or an ex-military FI, or a retired airline pilot than most low-time hours builders. In what other field of life are novices taught by anything other than well-qualified, experienced people? Just why is hours building as a FI considered acceptable?
