If you're flying the LNAV only or circling, remember that if you reach the MAP at RW32 you're over the displaced threshold
, not the beginning of the pavement.
We never factored the displaced threshold
into our line-speed check.
According to the NTSB's POH calculations, the airplane should have easily taken off and climbed out at its gross weight, with almost half the runway to spare (more, if the 190-foot distance from the displaced threshold
to the trees is considered.
Not quite sure what point you're trying to make about the displaced threshold
; all the numbers have to do with the actual usable threshold, not the pavement that happens to exist before that, so the displaced threshold
shouldn't matter to the previous discussion.
You'll know a displaced threshold
exists from a few sources.
Recovery of the displaced threshold
on the Runway 19 end and relocation of the associated markings, lighting, and signage.
If you watched the film of 16R, you may remember the cinematically convenient displaced threshold
that seems to truck on forever before actual runway numbers appear and invite the camera to land.
A temporary lighted displaced threshold
and temporary visual navigation aids will be constructed as a function of this first phase.
Two more warning signs are the fact that there is a displaced threshold
for Runway 22 and that the missed approach for Runway 4 requires a nonstandard climb gradient.
Tenders are invited for Runway 9 displaced threshold
Approaching a major airport, you note that the total runway length is 6,000 feet, with a 500 foot displaced threshold
on the end you plan to use.
This is true for this procedure, because the airport diagram doesn't indicate a displaced threshold
