For the professors on this message board, here's one:
To determine how much runway is available for landing, I always thought you take the most applicable of the following:
Take the threshold distance and subtract 1000 feet. The threshold is where you are supposed to be at 50 feet. Even though the ensuing air run is approximated to be 850 feet to 1500 feet, you subtract only 1000 feet.
Take the distance listed as landing distance beyond the glideslope. This is applicable when there is an instrument landing system and the aircraft is utilizing this via manual procedures, HUD, or autoland.
Take the distance NOTAM-ed due to a Temp. displaced threshold.
Would someone please add to this post with a definitive answer, thanks in advance.
Where's Lonnie when we need her.
FliFast, and landing slow.
