• ED Decision 2014/015/R found in: Air Operations (965/2012) Part-ARO Part-ORO Part-CAT Part-SPA Part-NCC Part-NCO Part-SPO (Feb 2025)

AMC1 CAT.OP.MPA.145(a) Establishment of minimum flight altitudes ED Decision 2014/015/R CONSIDERATIONS FOR ESTABLISHING MINIMUM FLIGHT ALTITUDES (a) The operator should take into account the following factors when establishing minimum flight altitudes: (1) the accuracy with which the position of the aircraft can be determined; (2) the probable inaccuracies in the indications of the altimeters used; (3) the characteristics of the terrain, such as sudden changes in the elevation, along the routes or in the areas where operations are to be conducted; (4) the probability of encountering unfavourable meteorological conditions, such as severe turbulence and descending air currents; and (5) possible inaccuracies in aeronautical charts. (b) The operator should also consider: (1) corrections for temperature and pressure variations from standard values; (2) ATC requirements; and (3) any foreseeable contingencies along the planned route.
