With many of the new aeroplanes out there, the technology is there to have an LPV approach to every single airfield in the uk....How many decades do you think this will take
I'd use ~800-1000' for be comfortably safe on a home made approach. Hand flying an ILS to 200' is not difficult if you have a nice stable approach...Now couple the autopilot to an LPV, chop the throttle at 50' and it'll even autoland you
