Modification of certain aircraft ACN following the ICAO decision (October 16, 2007)

Determination of ACN (Aircraft Classification Number) is based on an international standard that applies to aircraft with a mass on the ramp greater than 5700 kg.

ICAO has approved on October 16, 2007 the changing of the numerical coefficients entitled "Alpha factor" involved, for flexible pavement type, in calculating the ACN of the aircraft.

The ICAO decision led to recalculate the ACN "flexible" of landing gears of aircraft which have a total of at least four wheels.
