aircraft accident. Any damage or injury that occurs when an aircraft is moving with the intention of flight. aircraft alteration. The modification of an aircraft, its structure, or its components which changes the physical or flight characteristics of the aircraft. The Federal Aviation Administration classifies all alterations as either major alterations or minor alterations. See major alterations, minor alterations. aircraft approach category. A grouping of aircraft based on a speed of 1.3 times their stall speed in the landing configuration at maximum gross landing weight. Category A------------------Speed less than 91 knots Category B------------------Speed between 91 and 121 knots Category C------------------Speed between 121 and 141 knots Category D------------------Speed between 141 and 166 knots Category E ------------------Speed of 166 knotsor more aircraft basic operating weight. The basic weight of an aircraft, including the crew, ready for flight but without payload and fuel. This term is used only for transport aircraft. aircraft battery. A source of electrical energy for an aircraft that may be used for starting the engine and as auxiliary electrical power when the engine-driven generator is not operating. aircraft classes (wake turbulence separation). For the purpose of wake turbulence separation minimums, ATC has classified aircraft as heavy, large, and small: Heavy. Aircraft capable of takeoff weights of more than 255,000 pounds whether or not they operate at this weight during a particular phase of flight. Large. Aircraft of more than 41,000 pounds, maximum certificated takeoff weight, up to 255,000 pounds. Small. Aircraft of 41,000 pounds or less maximum certificated takeoff weight. aircraft classification (by certification weight). Classification of aircraft according to their maximum certificated gross weight: Small aircraft. Aircraft weighing up to 12,500 pounds certificated takeoff weight. Large aircraft. Aircraft of more than 12,500 pounds maximum certificated takeoff weight. aircraft control cable. Stranded steel cable used to actuate the controls of an aircraft. Aircraft control cable is made of either stainless steel or galvanized carbon steel. There are three types of aircraft control cable: nonflexible, flexible, and extra-flexible cable. Nonflexible cable is made of seven (1 x 7) or 19 (1 x 19) strands of steel wire. Flexible cable is made of seven strands of wire, with each strand having seven separate wires. This is called 7 x 7 cable. Extra-flexible cable, the one most generally used, is made of seven strands of wire, with each strand made of 19 small wires. Extra-flexible cable is called 7 x 19 cable and is used in locations where the cable must pass over a pulley. aircraft engine. 14 CFR Part 1: “An engine that is used or intended to be used for propelling aircraft. It includes turbosuperchargers, appurtenances, and accessories necessary for its functioning, but does not include propellers.” |
