FligHT PATH ANGLE
There seems to be some confusion regards height above sea level and height above ground level. The difference would be the threshold crossing height at 50 feet over the threshold.
What is the TCH (or the TZE) on runway 28L at SFO please ??
If I divide the 4300 ft AGL by 14 nm I would get a gradient of 307 ft per nm and thats AGL. I would have to add the TCH (TZE) to get altitude ASL.
By the way, that works out to be a 2.9 degree flight path angle. Not too bad as long as you don't go any lower.
Thanks.
