Reported departure and arrival times for this flight and airport.
Departure and arrival compared with schedule
Flight history details
| Date | Route | Scheduled departure | Reported ATD | Difference | Scheduled arrival | Landed | Difference |
|---|
What these differences mean: ATD − STD compares Flightradar24’s reported actual departure with scheduled departure. Landing − STA compares touchdown with scheduled arrival. These are not verified gate-to-gate delays: taxi time can affect the comparison. Your delay threshold is any actual gate departure after schedule (> 0 minutes); no 15-minute allowance is used. Missing records and estimates are excluded from historical averages.

How a delay probability would be calculated
Define a delayed departure as actual gate departure − scheduled gate departure > 0. A standard approach is logistic regression:
P(delay) = 1 / (1 + exp(−z))
z = β₀ + β₁r + β₂w + β₃g + β₄v + β₅p + β₆h
z = β₀ + β₁r + β₂w + β₃g + β₄v + β₅p + β₆h
Here r is the share of earlier resolved departures delayed at this airport; w is forecast wind speed, g gusts, v visibility, p precipitation, and h this flight’s historical delay rate. Only information available before the prediction time belongs in the model.
The β coefficients must be fitted to matched historical flights and weather, then tested on later dates. There is no universal set of coefficients. This page does not invent weights or turn a few observed flights into a calibrated percentage. Takeoff times cannot substitute for gate departure labels when training this model.
Research example using logistic regression for airport delays · This is a model family, not a validated SK935 forecast.
Saved observations, not a live feed. Reloading reads the latest published snapshot; it does not perform a new Flightradar24 lookup. Status and estimates can change after the displayed check time. Other flights or dates appear only after their records have been manually checked and added.
