Usually, it happens when your aircraft profile does not match the manufacturer fuel burn scheme. Specified Mach number of your AC can be used for the real flight for specific aircraft type or flight duration (short flight, long-haul flight etc.)
If you have other significant discrepancies in flight time calculated via Aviapages please contact us at support@aviapages.com sending following information:
- Tail number
- Route
- Issue description
- Date & Time of issue
- Aircraft type
- Departure and Arrival airports
- Number of passengers
After we check received info, we may require additional data such as FPM, mach number used for this type of flight, MTOW etc. and create customized aircraft profiles for your company. After creation of a customized profile we test it, advise you of its unique name and you use it for your calculations.
