| abbreviated precision approach path indicator |
A visual glide slope indicator (VGSI) consisting of only two light units normally situated on the left side of the runway in the form of a wing bar and indicating that the aircraft is on slope if the unit nearest the runway shows red and the unit furthest from the runway shows white, too high if both units show white, and too low if both units show red |

| abbreviated visual approach slope indicator |
A visual glide slope indicator (VGSI) consisting of only two light units normally situated on the left side of the runway, one upwind and one downwind, and indicating that the aircraft is on slope if the upwind unit shows red and the downwind unit shows white, too high if both units show white, and too low if both units show red |

| accident |
An occurrence associated with the operation of an aircraft which, in the case of a manned aircraft, takes place between the time any person boards the aircraft with the intention of flight until such time as all such persons have disembarked, or in the case of an unmanned aircraft, takes place between the time the aircraft is ready to move with the purpose of flight until such time as it comes to rest at the end of the flight and the primary propulsion system is shut down, in which (a) a person is fatally or seriously injured as a result of (i) being in the aircraft, or (ii) direct contact with any part of the aircraft, including parts that have become detached from the aircraft, or (iii) direct exposure to jet blast, except when the injuries are the result of natural causes, are self- inflicted or are inflicted by other persons, or when the injuries are to stowaways hiding outside the areas normally available to the passengers and crew; or (b) the aircraft sustains damage or structural failure that (i) adversely affects the structural strength, performance or flight characteristics of the aircraft, and (ii) would normally require major repair or replacement of the affected component, except for engine failure or damage, when the damage is limited to a single engine, its cowlings or accessories; or for damage limited to propellers, wing tips, antennas, probes, vanes, tires, brakes, wheels, fairings, panels, landing gear doors, windscreen, the aircraft skin (such as small dents or puncture holes) or for minor damages to main rotor blades, tail rotor blades, landing gear, and those resulting from hail or bird strike (including holes in the radome) or (c) the aircraft is missing or is completely inaccessible. Note 1 : For statistical uniformity only, an injury resulting in death within 30 days of the date of the accident is classified as a fatal injury by ICAO. Note 2: An aircraft is considered to be missing when the official search has been terminated and the wreckage has not been located. |
