Note

A flight stage is classified as either international or domestic based on the following definitions: International. A flight stage with one or both terminals in the territory of a State, other than the State in which the air carrier has its principal place of business.

Domestic. A flight stage not classifiable as international. Domestic flight stages include all flight stages flown between points within the domestic boundaries of a State by an air carrier whose principal place of business is in that State. Flight stages between a State and territories belonging to it, as well as any flight stages between two such territories, should be classified as domestic. This applies even though a stage may cross international waters or over the territory of another State.

Definition

The Landing Flare, in a fixed wing aircraft, is the transition phase between the final approach and the touchdown on the landing surface. This sub-phase of flight normally involves a simultaneous increase in aircraft pitch attitude and a reduction in engine power/thrust, the combination of which results in a decrease in both rate of descent and airspeed.

MOF

Definition

An aircraft state of motion, characterized by its Transversal and Longitudinal Accelerations. Examples are Left Turn, Right Turn, Climbing/Descending state, Uniform Motion, etc. MOF’s are used as input classes in the evaluation system - particularly for accuracy analysis. The classification of Modes-of-Flight (MOF) concerns modes in three directions transversal modes, longitudinal modes and vertical modes.
