Problems solved by technology

The disadvantage of this method of operation is that if the autopilot is disabled because the pilot has unconsciously pressed the autopilot disable button twice, there is no audible warning in the cockpit
In such a situation, the pilot may not be aware that the autopilot has been disabled, which could be detrimental to the flight of the aircraft

Embodiment Construction

[0021] exist figure 1 In a preferred embodiment depicted in , the aircraft acoustic warning device 1 according to the invention comprises first means 10 for monitoring the failure of the aircraft's autopilot and second means 12 for activating the sounding of the alarm in the cockpit. The first device 10 is connected via a link 20 to the autopilot 2 of the aircraft. Autopilot 2 communicates its activation / deactivation status to first device 10 via link 20 . This link 20 may be, for example, a digital data link. The first device 10 monitors the status of the autopilot and, upon detection of a change from an activated state to a disabled state, notifies the second device 12 of this change via eg a link 22 .

[0022] After the second device 12 receives the following information from the first device 10, that is, the autopilot 2 has switched from the activated state to the disabled state, it will figure 2 The instant t=0 depicted initiates the first sound with intensity I1. To...

Abstract

The invention relates to a method for producing an audible warning when an aircraft autopilot is deactivated. The method includes a) transmitting a first sound in the aircraft cockpit during a time ranging from a first predetermined value and a second predetermined value and b) transmitting a second sound in the aircraft cockpit. The invention also relates to an audible warning device having a monitoring unit for monitoring the deactivation of the aircraft autopilot and an activation unit for emitting an audible warning in the cockpit, where the activation unit is constructed such that it activates the first sound emission whose length ranges from the first predetermined value and a second predetermined value and a second sound when the monitoring unit detects the deactivation of the autopilot.

Description

technical field [0001] The subject of the invention is a method for generating an acoustic warning in the event of an aircraft autopilot failure. Another subject of the method is an aircraft comprising an autopilot capable of being disabled by implementing such an acoustic warning method. The invention also relates to an audible warning device for an aircraft capable of sounding an audible warning when the autopilot of the aircraft fails, and an aircraft incorporating such a device. Background technique [0002] Most aircraft, especially commercial transport aircraft, include an autopilot which enables the aircraft to fly automatically without action on the part of the pilot, for example during cruise flight. The pilot is therefore relieved of his flying duties during the cruise flight which may last several hours in a long-distance airliner flight. When the pilot does not wish to do so, he can disable the autopilot to revert to flying the aircraft himself. The pilot usua...
