That is in the proposed rule. So now F/Os will have to do steep turns, do a landing and a go around with the plane out of trim, perform a missed approach from a non ILS approach (along with the miss from a ILS) and if the airplane has more than 2 engines, they'll have to miss out of the OEI approach, lose a second engine and come back and land VFR. And if the FAA think the flaps can fail up, they'll have to do a no flap landing. I had to do a no flap landing for my 727 type last century but the Feds finally figured out the odds of a Boeing having a total flap failure are about nill and they've dropped the requirement in most Boeings.
So are you safer with the F/O holding altitude in 45 degree banked turn? The problem will be having enough Feds or ADPs to give the types. Currently a company check airman can give a F/O check ride but you need a Fed or an air carrier designee to issue the type.
