Method and electronic device for determining at least one fuel consumption domain for an aircraft, related computer program and electronic display system

The method according, to cairn 4, wherein the time variation between the modified duration for a respective iso-consumption curve and the duration taken into account for calculating the consumption limit curve is a multiple of five minute interval(s).

An electronic device for determining at least one fuel consumption domain for an aircraft, the device comprising:

• an acquisition module configured to acquire a flight envelope of the aircraft the flight envelope being a function of the altitude and a propulsion variable of the aircraft,
• a calculating module configured, for at least one respective flight phase, to calculate a fuel consumption limit curve as a function of the altitude and the propulsion variable, the consumption limit curve corresponding to an average consumption forecasted for said flight phase, and
• a determining module configured, for said at least one respective flight phase, to determine a fuel consumption domain as a function of the altitude and the propulsion variable, from the flight envelope and the consumption limit curve, the fuel consumption domain including a first consumption subdomain below the forecasted consumption for said flight phase and a second consumption subdomain above said forecasted consumption, the first and second consumption subdomains being separated by the consumption limit curve.
