Method and system for assisting the piloting of an aircraft in landing phase

A system to assist piloting of an aircraft in landing phase, the system being on board the aircraft and the system comprising:

• one or more processors and a non-transitory computer readable medium comprising executable instructions, wherein the executable instructions comprise:
• a generation module configured to generate a reference braking datum depending on a reference runway state;
• a determination module configured to determine local information depending on a local runway state characterizing an area of runway on which the aircraft is in movement during landing;
• an update module configured to update the reference runway state when the local information indicates that a local runway state is worse than the reference runway state, the generation module being further configured to generate an updated braking datum depending on the updated runway state;
• and
• a brake assist module configured to receive the reference braking datum as input, followed by the updated datum, if applicable, configured to generate a braking setpoint for controlling a brake device of the aircraft,
• wherein the local information comprises a local stopping distance estimated on the basis of local measurements made in the aircraft, and
• a obtaining module configured to obtain a reference stopping distance from the reference braking datum;
• and
• a comparator configured to compare a relative difference between the local stopping distance and the reference stopping distance with a predetermined threshold value, in order to determine whether or not the local runway state is worse than the reference runway state,
• wherein the system is in electronic communication with and configured to control the brake device of the aircraft.

An aircraft comprising at least one pilot landing assist system comprising:

• one or more processors and a non-transitory computer readable medium comprising executable instructions, wherein the executable instructions comprise:
• a generation module configured to generate a reference braking datum depending on a reference runway state;
• a determination module configured to determine local information depending on a local runway state characterizing an area of runway on which the aircraft is in movement during landing;
• an update module configured to update the reference runway state when the local information indicates that a local runway state is worse than the reference runway state, the generation module being further configured to generate an updated braking datum depending on the updated runway state;
• and
• a brake assist module configured to receive the reference braking datum as input, followed by the updated datum, if applicable, further configured to generate a braking setpoint for controlling a brake device of the aircraft,
• wherein the local information comprises a local stopping distance estimated on the basis of local measurements made in the aircraft, and
• an obtaining module configured to obtain a reference stopping distance from the reference braking datum;
• and
• a comparator configured to compare a relative difference between the local stopping distance and the reference stopping distance with a predetermined threshold value, in order to determine whether or not the local runway state is worse than the reference runway state,
• wherein the pilot landing assist system is in electronic communication with and configured to control the brake device of the aircraft.
