Actual Dep And Arr Times

Sun Mar 14, 2004 2:40 am

When determines the departure and arrival times?

When the plane leaves the gate?

Thanks in advance! -- Scott

Usually, for the airline, when the door is closed for departure, the aircraft has departed.

The aircraft has arrived when the brakes are set at the gate.

The aircraft has arrived when the brakes are set at the gate.

is this the same criterion for airports, since the boards show the actual landing time...

I think the departure time determines when the aircraft is off block. I'm not certain though if the boards show the time when the aircraft actually lands or the time it is on block.

Published departure and arrival times are for gate departure and gate arrival. Actual departure/arrival times are dependent upon the individual airline's procedures. Most USA airlines use actual parking brake release for departure and final parking brake "set" for arrival times. You will see significant variations on the latest published arrival time on airport monitors because we (pilots) are guessing what the actual landing time will be and the airline guesses [normally using historical data] on how long it will take to park at the gate after landing. Many, many variables will change the actual times from these guesses.

Generally the airline counts the time the plane moves off the gate as departure and the time the brakes are set as arrival.

Definition of times - for airlines... (and crews) -
xxx
Block OUT time, time at which airplane is pushed back, or moves.
Takeoff time, time at which power is applied for takeoff.
Landing time, time at which the aircraft lands.
Block IN time, time at which blocks are placed forward/aft of wheels at gate.
xxx
The airline schedules are based on block time (Block OUT - Block IN).
ATC and flight plans use takeoff and landing times.
Flight hours for airplanes (maintenance, airplane age) is takeoff to landing.
Flight hours for crew (flight pay if applicable) is Block OUT to Block IN.
