Since not every flight on a given route is loaded equally there may be efficiency gained or lost as a result of loading. If the slot time changes but the departure time remains the same an airline may chose to slow the plane a bit (or speed it up a bit) to compensate.Īircraft Loading: Aircraft efficiency (and subsequently speed) will vary a bit with the loading of the aircraft. Landing Slots: There are 5 high density airports here in the US (and presumably others elsewhere) that require planed ahead landing slots. This may add to the time spent in the air for a given flight depending on the hold. So, if you enter the start and end locations, dates, and times of your flight, the Time Zone Duration Calculator will calculate the true travel time for you.

That's a 200 Knot ground speed difference which can really make an impact on flight time.ĪTC Holds Vary: ATC for various reasons may put a plane into a holding pattern on arrival. Flight duration is a commercial aviation term that commonly refers to the amount of time a single flight (segment) is scheduled to take from 'pushing back at the departure gate to arriving at its destination gate'. Chocks off to Chocks on is Block time & is calculated. The winds aloft vary seasonally, which can affect flight times for summer versus winter trips. So lets say a long haul flight has a 100 Knot headwind half the year and a 100 Knot tail wind for the other half. Duration of Flight is taken from Take off to Touch down and is calculated as Time in Air. Keep in mind that this can be in any direction. Winds at common cruising altitude can sometimes reach well into the 100 Knot spectrum.

On average, the duration of a flight from Paris to New. Wind: The biggest factor in this is wind. The Gleim Pilot Logbook makes it easy to track all of your flight time. Pushed by the jet-stream, planes travel faster, reducing flight hours between New York and Paris.
