displaced threshold

A threshold is located at some distance away the beginning of a runway, but it does not include the downwind end of the runway. Areas reached prior to the displaced threshold are not permitted for landing, but they may be used for takeoff and taxiing.

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.

Displacement effect

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.

Devil in the details

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.

Overgross: flying your aircraft above its maximum gross weight can be done, but not in all circumstances

You'll know a displaced threshold exists from a few sources.

You cant land on that

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.

Famous pavement

The airport manager said the airplane began its takeoff on the 2500-foot-long Runway 13 from the displaced threshold, which is 400 feet from the approach end of the runway.

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.

Caution while circling: a circling approach can be the most nerve wracking and potentially dangerous completion of an approach. Even so, what lies beneath the circling area might still surprise you

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.

The quiz

This is true for this procedure, because the airport diagram doesn't indicate a displaced threshold. Therefore the available landing distance is the physical runway distance shown on the airport diagram.

The quiz

Determining the kind of displaced threshold requires some digging.
