Review the performance-data basis and limitations.
G-BOIY: the supplied 1978 C172N POH is the performance source used by the calculator.
G-BRBA: the supplied PA-28-161 Report VB-880 POH is the performance source used by the calculator.
The calculator is limited to the source data it implements and does not extrapolate beyond the published chart/table ranges. Official NATS UK AIP data is used for covered UK aerodromes; weather inputs remain editable and source-labelled.
Development tool only. Verify every result against the applicable POH/AFM, supplements, current aerodrome publications and actual conditions.
