Thresholds are counted as part of the runway, and are included in the runway size.
Threshold crossing height (TCH). The theoretical height above the runway threshold at which the aircraft's glide slope antenna would be if the aircraft maintains the trajectory established by the mean ILS glide slope or MLS glide path.

Threshold: The designated beginning of the runway that is available and suitable for the landing of aircraft.
Runway threshold - The beginning of that portion of the runway usable for landing.

THRESHOLD BONUS: An incentive offered to members of a program's elite level. Additional miles or points are awarded to members who reach a specific membership level or "threshold."

The threshold for the active runway, 27, is just ahead, and we're cleared to taxi into position and take off. Your maximum cruise configuration is called for on this flight.

THR or thld - threshold.
TMA - Terminal Control Area. An area of controlled airspace at the intersection of airways
in the vicinity of control zones (CTRs) around major airports.
TO - take-off (sometimes TKOF).
3By the way, you should make sure your line of sight to the threshold is unobstructed. At night, if the green threshold lights are blinking or can't be seen at all, it tells you there is an obstruction between them and the airplane. Add power! ...
2 km (3.9 NM) from the threshold except that, where this distance is not practicable, the outer marker may be located between 6.5 and 11.1 km (3.5 and 6 NM) from the threshold. The modulation is repeated Morse-style dashes of a 400 Hz tone.
A function in which the algorithm for computing output changes at defined events or thresholds, such that output follows one path as input increases and another path as input decreases; Hysteresis can be formalized: (0) at initialization, ...
Given the numbers, if you put a C-172’s main gear right on the threshold, in theory you should be able to land it in 550 feet without smoking the tires.
When trying to stretch the glide, if you actually make it to the runway you arrive at the threshold of the runway with too little airspeed (and lift) to carry through with the level off, flare and touch down.
Make sure that you're not using too high an approach speed when crossing the threshold. This is the single most common mistake made by pilots during the landing flare. Excessive speed combined with excessive power can easily lead to floating.
Some respected aerospace researchers have placed the threshold of space at lower altitudes than the USAF and NASA, so many X-15 pilots could also be considered as astronauts.
This line of lights is place 1000ft from the runway threshold, and is used as a visible horizon to help a pilot transfer from Instrument flight to Visual flight.
Typically this is a relay which trips if output voltage exceeds some threshold. These circuits are normally reset by turning off the alternator/generator for a few seconds, and then turning it back on.
Classification of, and requirements for, instrument flight procedures that permit aircraft to descend to no lower than 60 meters (200 feet) above the runway threshold provided weather conditions meet the minimum visibility requirements typically at ...

When I took off from 23 at Latrobe we were off the ground well before the displaced threshold which is at 850 ft. The plane was at max gross and the density altitude was
almost 3000ft.
accompanying his work, and about the work itself, which seems to suggest that he had more knowledge to impart than he chose to make public--or else that he came very near to complete solution of the problem of flight, and stayed on the threshold ...
