tarpaulin. A large piece of heavy, waterproof canvas, fitted along its edges with eyelets. Ropes can be tied through the eyelets to hold the tarpaulin tight over whatever device it is protecting. TAS. True airspeed. See true airspeed. tautening dope (aircraft finishing material). A finishing material brushed or sprayed on the fabric used to cover the framework of an aircraft. Aircraft dope has a film base of cotton fibers dissolved in certain acids and mixed with solvents and thinners. Plasticizers are mixed into the dope to give it resilience and keep it from being brittle. When the dope is put on the fabric, it encapsulates, or surrounds, the fibers of the cloth, and as it dries, it shrinks and pulls the fibers close together. This shrinks, or tautens, the fabric on the framework. Some inorganic fabrics used to cover aircraft are shrunk with heat, and a special nontautening dope must be used with them. Nontautening dope does not shrink as much as tautening dope as it dries. taxi (aircraft operation). To move an aircraft along the ground or water under its own power, at a slow speed. An aircraft is taxied from an airport terminal to the runway, where it takes off. “Taxi into position and hold” (air traffic control). A phrase used by ATC to inform a pilot to taxi onto the departure runway in takeoff position and hold. It is not authorization for takeoff. This instruction is used when takeoff clearance cannot immediately be issued because of traffic or other reasons. taxi light (aircraft external light). A light, similar to the landing light, installed on an aircraft in such a way that it illuminates the runway or taxiway when the aircraft is on the ground in its normal attitude for taxiing. taxiway (part of an airport). A paved strip that parallels the runways. Aircraft move along the taxiways from the terminal to the end of the runway so they will not interfere with aircraft using the runway for takeoff and landing. TBO (time between overhauls). A time period specified by the manufacturer of an aircraft engine as the maximum length of time the engine should be run between overhauls without normal wear causing parts of the engine to be worn beyond safe limits. TBO depends upon the engine being operated properly and maintained in accordance with the engine manufacturer’s recommendations. The overhaul of an engine when it reaches its TBO hours is not mandatory except for certain commercial operators that have this requirement written into their operations manual. TCA (terminal control area). Controlled airspace extending upward from the surface or higher to specified altitudes within which all aircraft are subject to operating rules and pilot and equipment requirements specified in 14 CFR Part 91. TCAS (traffic alert and collision avoidance system). An electronic warning system installed in an aircraft that detects nearby aircraft and warns the pilot, showing the range, altitude, and course of the impending threat. The TCAS informs the pilot of the appropriate maneuver to use to avoid a collision. |
