Abstract
A method for obtaining updated travel condition data at a vehicle is provided. The method identifies a subset of a predetermined travel route that is ahead of the vehicle, based on a selected distance quantity and a current position of the vehicle during traveling; and requests a set of data for the subset, the updated travel condition data comprising the set of data.
Claims14
A method for obtaining updated travel condition data onboard an aircraft during flight, the method comprising:
- obtaining a current position of the aircraft, by at least one processor communicatively coupled to a navigation system onboard the aircraft;
- receiving user input indicating a selected distance quantity of a predetermined travel route, via a user interface communicatively coupled to the at least one processor;
- identifying:
- a current subset of the predetermined travel route that is ahead of the aircraft, by the at least one processor, based on the selected distance quantity and the current position of the aircraft during traveling;
- and
- future subsets of the predetermined travel route, based on the selected distance quantity and previously-traveled subsets behind the aircraft during travel;
- requesting a set of data for the current subset, via a communication device communicatively coupled to the at least one processor, the set of data comprising aeronautical information system (AIS) data and meteorological (MET) data for the current subset, the updated travel condition data comprising the set of data;
- receiving the set of data, via a satellite uplink to a communication device onboard the aircraft, in response to requesting the set of data;
- presenting the set of data onboard the aircraft, via a display element communicatively coupled to the at least one processor;
- automatically requesting updated data for one of the future subsets when the aircraft reaches the one of the future subsets, based on a later position of the aircraft and the selected distance quantity, wherein the updated data comprises AIS data and MET data for the one of the future subsets;
- receiving the updated data, via the satellite uplink to the communication device onboard the aircraft, in response to automatically requesting the updated data;
- and
- presenting the updated data onboard the aircraft, via the display element.
