The present disclosure provides for informed de-icing by identifying a travel time range for an aircraft from a de-icing station to a runway; identifying a holdover window based on predicted weather conditions during the travel time range; estimating a takeoff time for the aircraft based on a takeoff queue for the runway and the travel time range; and in response to the holdover window expiring before the estimated takeoff time, delaying the aircraft from de-icing. In some aspects, informed de-icing includes, in response to identifying an aircraft scheduled for de-icing within a caution threshold of a scheduled takeoff time and to determining that a push time cannot be delayed: evaluating an effect of repeating a de-icing operation for the aircraft on flight operations; and in response to the effect exceeding an impact threshold: rescheduling the de-icing operation for the aircraft based on a new takeoff time.

A method for determining transition height elements in a flight climbing stage based on constant value segment identification comprises the steps of splitting a speed component and a Mach component from a flight track, and performing linear interpolation on the two respectively; discretizing the interpolated speed component, and setting a threshold for filtering to obtain a speed discrete value set; identifying a constant-speed segment, and acquiring a maximum constant-speed value and a maximum moment of the constant-speed segment; keeping the Mach component of the track with a time no less than the constant-speed maximum moment; discretizing the kept Mach components, and filtering to obtain a Mach discrete value set; identifying a constant-Mach segment, and acquiring a constant-Mach value corresponding to a minimum moment of the constant-Mach segment; and calculating a transition height in the flight climbing stage according to the constant-speed value and the constant-Mach value obtained.
