Assistance method for assisting flying of an aircraft with restriction of possibilities of adjusting the flying parameters depending on the context, and corresponding device

A flying assistance device for assisting flying of an aircraft, comprising:

• a memory in which a plurality of preprogrammed flying modes are stored;
• a mode configuration system for configuring at least one flying mode, so as to form a configured flying mode, the control interface comprising:
• a flying mode selector for the selection, by a user, of a selected flying mode from among at least one available flying mode taken from among the preprogrammed flying modes, and
• a setpoint input member for the input, by a user or by an avionics system, of at least one flying setpoint associated with the selected flying mode;
• a presentation member for presenting, to the user, the or each configured flying mode and the associated flying setpoint;
• a mode engaging system for engaging at least one configured flying mode, the configured flying mode becoming an engaged flying mode;
• an automatic pilot system of the aircraft, configured to fly the aircraft based on the flying setpoint of the or each engaged flying mode;
• an avionics parameter collector to collect at least one avionics parameter of the aircraft;
• and
• a command limiter to restrict the flying mode configuration possibilities based on the or each collected avionics parameter.
