Straight out of the Oxford Air Law syllabus:
On leaving the enroute phase Minimum Obstacle Clearance (MOC) 300m
Inital Approach Fix (IAF) set QNH - MOC 300m
Intermediate Fix (IF) (QFE advised) MOC 300 down to 150m
Final Approach Fix (FAF) (optimum 5nms - maximum 10nms) where specified the MOC is 75m (this is for a non precision approach!)
The spiel for a precision approach is:
"The lowest altitude (OCA) or height above the elevation of the relevant runway threshold (OCH), at which a missed approach must be initiated to ensure compliance with the appropriate obstacle clearance criteria"
And it was just starting to make sense!
I'm just a dumb ATPL student struggling to get to grips with Air Law, perhaps someone with real experience at the sharp end could give a better answer!
