METHOD FOR AVOIDANCE OF ONE OR MORE OBSTACLES BY AN AIRCRAFT, AND RELATED COMPUTER PROGRAM PRODUCT, ELECTRONIC SYSTEM AND AIRCRAFT
First Claim
1. A method of avoidance of one or more obstacles by an aircraft comprising a warning system capable of generating alerts as a function of the proximity of the obstacle(s), and an electronic avoidance system, the method being implemented by the electronic avoidance system, the method comprising:
- a) generating an alert by the warning system on detection of an obstacle;
b) if no manual avoidance maneuver is detected for a time period longer than a first determined time period effective from issue of the alert by the warning system and if the alert is maintained during this first time period, automatically activating an automatic avoidance guide mode to determine an obstacle-avoidance guidance rule, the determination of the guidance rule comprising the determination of at least one speed and/or heading set-point and the computing of the avoidance guidance rule as a function of the determined set-point(s); and
c) if an autopilot device of the aircraft is coupled to the automatic avoidance guide mode, transmitting to the autopilot device the avoidance guidance rule determined in step b) for automatic performing of a maneuver to avoid the obstacle by action on one and/or the other of two primary control members of the aircraft causing the aircraft to reach the set-point(s), the warning system being capable of generating alerts of at least a first and second type, step b) only being implemented in the event that the alert generated by the warning system is an alert of second type.

Abstract
A system and method for the avoidance of one or more obstacles by an aircraft, and a related computer program product, electronic system and aircraft are disclosed. In one aspect, the method includes a) generating an alert by a warning system on detection of an obstacle and b) if no manual avoidance maneuver is detected for a time period longer than a first determined time and if the alert is maintained during this first time period, automatically activating an automatic avoidance guide mode to determine an obstacle-avoidance guidance rule. The method further including c) if an autopilot device of the aircraft is coupled to the automatic avoidance guide mode, transmitting to the autopilot device the avoidance guidance rule determined in step b) for automatic performing of a maneuver to avoid the obstacle.

12. An electronic avoidance system of one or more obstacles by an aircraft comprising a warning system capable of generating alerts as a function in particular of the proximity of the one or more obstacles, the electronic avoidance system comprising a memory having stored thereon software configured to cause a processor to determine a guidance rule for avoidance of an obstacle indicated by an alert generated by the warning system, the memory being further configured to cause the processor to determine a guidance rule, to determine at least one speed and/or heading set-point, and to compute the avoidance guidance rule as a function of the determined set-point(s),
the electronic avoidance system further comprising an activator configured to: -
(i) automatically—
if no manual avoidance maneuver is detected for a time period longer than a first determined time period effective from issue of the alert by the warning system and if the alert is maintained during this first time period—
activate an automatic obstacle-avoidance guide mode for determination of an obstacle-avoidance guidance rule by the determination units;(ii) transmit the computed avoidance guidance rule to the autopilot—
if an autopilot device of the aircraft is coupled to the automatic avoidance guide mode—
for automatic performing of an avoidance maneuver of the obstacle by action on one and/or the other of two primary control members of the aircraft, to cause the aircraft to reach the set-point(s),the warning system being configured to generate alerts of at least a first and second type, automatic activation only being implemented in the event that the alert generated by the warning system is a second type alert. - View Dependent Claims (13, 14)
