Abstract
Described is a method of updating meteorological information for an aircraft, which includes automatically providing a request by an on board computer (FMS, flight management system) for the meteorological data so as to anticipate the updating of the latter as soon as an update is available. This automation allows the crew to have the data ready for display and use without waiting, to reduce and smooth the workload of the crew by anticipating the request and the processing of these data, and to limit the potential confusion associated with the receipt, hitherto verbal, of the ATIS (Air Traffic Information Service) information.

A method of updating meteorological information for an aircraft, said method comprising:
- automatically and periodically requesting meteorological data by an onboard computer to anticipate an update as soon as the update is available,
- wherein the request for meteorological data comprises the steps:
- providing a request by the computer to update the meteorological data with a ground via an air-ground datalink,
- storing the meteorological data in memory as soon as the data are received,
- verifying a pertinence of updating existing data according to the stored data when new data are different from the stored data,
- raising an alarm if the new data compromise the accessibility of a destination airport or an alternative airport,
- notifying a crew that the new data is available for checking and validating before use by the onboard computer,
- updating forecasts and performance data affected by taking account of the new data, and
- displaying the forecasts and performance data on a specific interface.
