Starter feature. Available on your Jet Tracker account.
Manufacturer-published distances at sea level, ISA and reference weight. Not corrected for altitude, temperature, wind or runway condition, takeoff included. Uses the declared LDA as a proxy for effective runway length (RBAC 135.361) and the most favourable threshold in calm air (135.385(b)(1)): on the day, wind may force the shorter threshold. Destination only: does not assess the alternate aerodrome (135.387). Not a substitute for the AFM or the operator's performance analysis. Rule: RBAC 135.385 and 135.398; private flying (RBAC 91) is not factored. Runways: declared distance (LDA) from AISWEB/DECEA (2026-09-05), checkable on each aerodrome chart; where DECEA publishes no declared distance, physical length from OurAirports is used.
