ABSTRACT:
A method of automatically guiding an aircraft for flight at low altitude determines an LLF (low level flight) trajectory section for following terrain to be overflown by the aircraft. The LLF trajectory section takes account of predictions of the aircraft's mass and speed and climb and descent performance. The LLF trajectory section includes an entry point and an exit point. The LLF trajectory section is integrated between a first trajectory part corresponding to a first phase of flight and a second trajectory part corresponding to a second phase of flight, by providing respectively first and second transition phases. The aircraft is automatically guided so that it successively captures, follows, and leaves the LLF trajectory section.
