Flight planning

EOBT is off-block time. Estimated take-off adds the taxi allowance; estimated landing then adds still-air route time at the selected planning TAS.

Data and limitations

G-BOIY: standard 1978 C172N POH dataset. Aircraft-specific engine, propeller, supplements and modifications remain unconfirmed.

G-BRBA: PA-28-161 Report VB-880 dataset. The nomograph model remains beta and is not confirmed as aircraft-specific.

Airport/runway metadata, METAR and TAF data are retrieved from NOAA AviationWeather.gov. Hourly temperature and pressure forecasts use Open-Meteo. All fetched values remain editable.

Development tool only. Verify every result against the applicable POH/AFM, supplements, current aerodrome publications and actual conditions.
