Work out duty time limit instantly with clear inputs, formula shown and shareable results.
Flight duty period limits shorten as sectors increase and as the reporting time moves into the early morning or night. This models the common structure: a base limit reduced by about half an hour for each sector beyond two, with a further reduction for duties starting in the night window.
Flight duty period
FDP = base limit - 0.5 h per sector above two - night/early start reduction, floored at 9 h
Aviation results are planning estimates only. Always verify take-off, landing, fuel, weight and balance figures against the certified Aircraft Flight Manual, current performance charts and applicable aviation regulations before flight.
No. The real tables (for example EASA ORO.FTL or your national equivalent) are specific to reporting time, sectors and acclimatisation state, and must be applied directly.
Most schemes allow a limited commander's discretion extension for unforeseen circumstances, with reporting requirements attached.
