An aid method for controlling the energy situation of an aircraft. The method includes determining (i) an energy meeting point corresponding to a constraint point, (ii) a meeting type based on the constraint at the constraint point, (iii) an energy state of the aircraft relative to a reference altitude profile determined by a flight management system, (iv) a high-energy joining profile representative of a future path of the aircraft with an energy dissipation strategy, and (v) energy deviations relative to the high-energy joining profile. Determining the high energy joining profile is carried out backwards depending on the type of meeting and the energy state of the aircraft. The energy deviations are displayed to an operator of the aircraft.
