AIRSPACE_OCCUPANCY_PHASE

The phase of flight during which the aircraft flies within a given airspace.

type: enum value

UNKNOWN_PHASE

Phase of flight is not discernable from the information available

type: enum value

UNCONTROLLED_DESCENT_PHASE

The phase of flight in which an uncontrolled descent from a previously normal manoeuvre occurs.

type: enum value

TAXI_OUT_PHASE

Phase of flight from Off-Block until Take-Off, that includes the Surface Movement associated to the departure of a flight

type: enum value

TAXI_IN_PHASE

Phase of flight from Landing until In-Block, that includes the Surface Movement associated to the arrival of a flight.

type: enum value

TAKEOFF_PHASE

The phase of flight from the application of take-off power until reaching the first prescribed power reduction, or until reaching the vfr pattern or 1,500 feet (450 metres) above runway end elevation, whichever comes first or the termination (abort) of the take-off.

type: enum value

STAY_PHASE

A period of 'special activity' when the aircraft will 'stay' in the area defined for a given length of time.

type: enum value

STANDING_OUT_PHASE

The phase of a flight from the start of activities preparing the aircraft for a flight until the start of the taxi out.

type: enum value

STANDING_IN_PHASE

The phase of a flight starting from end of taxi in and ending when all activities related to the aircraft for the performed flight has been completed.

type: enum value

LANDING_PHASE

The phase of flight from the point of transition from nose-low to nose-up attitude, immediately before landing (flare), through touchdown and until aircraft exits landing runway or comes to a stop, whichever occurs first.

type: enum value

INTERMEDIATE_APPROACH

The phase of flight between the middle approach fix and the final approach fix; or between the end of a reversal procedure or dead-reckoning track procedure and the final approach fix.

type: enum value

INITIAL_CLIMB_PHASE

The phase of flight from 50 feet [15 metres] above runway end elevation to the first prescribed power reduction, or until reaching 1500 feet (450 metres).

type: enum value

FINAL_APPROACH_PHASE

That part of an instrument approach procedure which commences at the specified final approach fix or point, or where such a fix or point is not specified, a) at the end of the last procedure turn, base turn or inbound turn of a racetrack procedure, if specified; or b) at the point of interception of the last track specified in the approach procedure; and ends at a point in the vicinity of an aerodrome from which: 1) a landing can be made; or 2) a missed approach procedure is initiated.

type: enum value

ENROUTE_PHASE

The phase of flight from the completion of initial climb at the departure aerodrome to the completion of controlled descent to the outer marker [ifr] or [vfr] to completion of the controlled descent to the vfr pattern or 1,500 feet [450 metres] above runway end elevation, whichever comes first.

ENROUTE_HOLDING_PHASE

The phase of flight, in which a pre-determined ad-hoc manoeuvre occurs, which keeps the aircraft within a specified airspace en-route awaiting further instructions.

type: enum value

EMERGENCY_DESCENT_PHASE

The phase of flight in which an intentionally rapid or premature descent, from a previously normal manoeuvre, is made in response to an in-flight emergency. the descent is controlled by the crew.

type: enum value

DESCENT_PHASE

Descent phase.

type: enum value

CRUISE_PHASE

The phase of flight from the top of climb to cruise altitude, or flight level, to the start of the descent toward the destination aerodrome or landing site.

type: enum value

CLIMB_PHASE

Climb phase.

type: enum value

CHANGE_OF_CRUISE_LEVEL_PHASE

The phase of flight during which the aircraft climbs, or descends, from one cruising flight level or altitude to the next cruising flight level or altitude.

type: enum value

APPROACH_PHASE

The phase of flight from the outer marker to the to the point of transition from nose-low to nose-high attitude immediately prior to the flare above the runway [ifr]; or [vfr] from 1500 feet (450 metres) above the runway end elevation or from the point of vfr pattern entry to the flare above the runway.

type: enum value

APPROACH_HOLDING_PHASE

The phase of flight in which a pre-determined ad-hoc manoeuvre during the approach keeps the aircraft within a specified airspace awaiting further instructions.
