Heavy metal glide approaches
Not a problem in my last legacy carrier but in 1979 they decided a stabilised approach was necessary from 300ft..on all types.the regulation was final approach configuration selected by 400ft.
I used a gate of selected by 500ft on short haul and 700ft on the DC10. The latter because some months I only did a couple of landings.
After one of the all engine flame outs we practised glide approaches on the Sims too.
best technique was the French system of constant angle which I taught on sailplanes.
