This has been discussed here several times.
The certification criteria on which GPS NPA approaches are based alledgedly requires the Foxtrot waypoint.
All that means of course is the original designer had no idea what he was doing.
The Foxtrot waypoint is dangerous...the GPS NPA is essentially the only approach where the final descent profile, in its entirety, is not based on a distance to a MAP.
It is a sick joke...I would bet folding money this is a significant contributing factor in a least one fatal crash I am aware of....there will be more.
If the certification basis for GPS NPA 'requires' this idiocy then
CHANGE THE CRITERIA
