Terminal arrival area (TAA). A procedure to provide a new transition method for arriving aircraft equipped with FMS and/or GPS navigational equipment. The TAA contains a “T” structure that normally provides a NoPT for aircraft using the approach. TERP. See terminal instrument approach procedure. Terrain Awareness and Warning System (TAWS). A timed-based system that provides information concerning potential hazards with fixed objects by using GPS positioning and a database of terrain and obstructions to provide true predictability of the upcoming terrain and obstacles. TFR. See temporary . ight restriction. 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. Thrust (aerodynamic force). The forward aerodynamic force produced by a propeller, fan, or turbojet engine as it forces a mass of air to the rear, behind the aircraft. Time and speed table. A table depicted on an instrument approach procedure chart that identi.es the distance from the FAF to the MAP, and provides the time required to transit that distance based on various groundspeeds. Timed turn. A turn in which the clock and the turn coordinator are used to change heading a de.nite number of degrees in a given time. TIS. See traffic information service. Title 14 of the Code of Federal Regulations (14 CFR). Traffic Alert Collision Avoidance System (TCAS). |
