(ii)  
would normally require major repair or replacement of the affected component, except for engine failure or damage, when the damage is limited to the engine, its cowlings or accessories; or for damage limited to propellers, wing tips, antennas, tires, brakes, fairings, small dents or puncture holes in the aircraft skin; 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.

Fr: accident d’aéronef
aircraft approach category
The grouping of aircraft based on speed. The categories are as follows:
(a)
Category A – speed up to 90 kt;

(b)
Category B – speed of 91 to 120 kt;

(c)
Category C – speed of 121 to 140 kt;

(d)
Category D – speed of 141 to 165 kt; and

(e)
Category E – speed above 165 kt.

Fr: catégorie d’aéronefs pour l’approche
aircraft autonomous integrity monitoring A technology used to augment global positioning systems (GPS) and global orbiting navigation satellite systems (GLONASS) within the global navigation satellite system (GNSS) 1 framework that uses information from the aircraft inertial navigation systems to cross-check the integrity of the GPS signal. 
.  abbreviation: AAIM
Fr: contr.le autonome d’intégrité à bord
aircraft-based augmentation system
An augmentation system which augments and/or integrates the information obtained from the other GNSS elements with information available on board the aircraft.
.  
abbreviation: ABAS

system (LAAS), and wide area augmentation system (WAAS)

Fr: système de renforcement embarqué
aircraft call sign
A group of alphanumeric characters used to identify an aircraft in air-ground communication.
Fr: indicatif d’appel d’aéronef
aircraft captain
(1)
Other expression for: pilot-in-command (PIC)

(2)
DND: A pilot with first pilot qualifications who has been designated pilot-in-command of an aircraft and who is responsible for the operation and safety of that aircraft. 

Fr: commandant de bord
aircraft classification number ICAO: A number expressing the relative effect of an aircraft on a pavement for a specified standard subgrade category. Note: ACNs are expressed on a scale from approximately 5 (least demanding aircraft) to 110 (most demanding aircraft). ACNs are applicable only to aircraft having an apron (ramp) mass equal to or greater than 12 600 lb. ACNs have been assigned to present-day aircraft at their maximum and minimum operating masses/weights and at a specific tire pressure. The ACN should not exceed the pavement classification number (PCN) for unrestricted aircraft operations. The ICAO ACN system is the internationally approved and accepted method for ranking aircraft in terms of their pavement-strength requirements.
