Definitions
- the subject of the invention is an audible warning method when deactivating an autopilot of an aircraft. It also relates to an aircraft comprising an autopilot capable of being deactivated by implementing this audible warning method. The invention also relates to an audible warning device for an aircraft capable of emitting an audible warning when deactivating an autopilot of this aircraft, and an aircraft comprising such a device.
- the pilot is thus relieved of the piloting tasks during these phases of cruise flight which can last several hours on long haul flights.
- the pilot can deactivate the autopilot in order to resume piloting the aircraft himself.
- the driver usually has a button that he can press to disable the autopilot. In the case of Airbus A320, A330, A340 ... this button is located on the mini-stick used to control the movements of the aircraft.
- the autopilot is deactivated, regardless of the pilot's wish (autopilot failure ...) or without pressing the autopilot deactivation button (action on the rudder pedals, action on the mini-stick ).
- an alert is activated in the cockpit to warn the pilot of the deactivation of the autopilot, in case this deactivation is involuntary or not controlled by the pilot, and would have gone unnoticed.
- This alert is usually composed of visual alerts (display of text messages and activation of indicator lights) and an audible alert.
- this audible alert can disrupt the pilot in its activities, especially when it corresponds to a voluntary deactivation of the autopilot on the initiative of the pilot, by pressing the button.
- the pilot can acknowledge it by pressing the button. Acknowledgment of this audible alert is therefore requested by the pilot by a second press on this button in the case of a voluntary deactivation of the autopilot or by a first pressing on the same button in the case of disabling the autopilot unintentional or not controlled by the pilot.
- This mode of operation has the disadvantage that in case of disabling the autopilot resulting from a double unintentional pilot support on said autopilot deactivation button, no sound alert is emitted in the cockpit. In such a case, the pilot is not aware of said disabling of the autopilot, which can be detrimental to the flight of the aircraft.
- the acoustic intensity corresponding to the second sound is greater than the acoustic intensity corresponding to the first sound.
- the sound alert is less disruptive to the pilots of the aircraft than during the emission of the second sound.
- the transmission of the second sound has the effect of attracting more attention from the pilots to the sound alert.
- the emission of the first sound, in step a) is maintained for a duration corresponding to said first predetermined value in the event of acknowledgment of said sound alert by a pilot of the aircraft during said duration.
- the duration of the first sound then corresponds to said minimum duration, so that the sound alert disturbs the drivers as little as possible.
- the acknowledgment of the sound alert by a pilot of the aircraft has the effect of canceling the emission of the second sound.
- the second sound is not emitted and therefore the audible alert affects the pilots as little as possible.
- the audible alarm is not acknowledged during the transmission of the first sound, the second sound is emitted.
- the emission of the second sound has the effect of attracting more attention from the pilots to this sound alert and thus to improve the awareness of disabling the autopilot. If a pilot then acknowledges this sound alert, the emission of the second sound is canceled after this acknowledgment.
- the invention also relates to an aircraft comprising an autopilot capable of being deactivated by implementing an audible warning method as mentioned above.
- the invention also relates to an audible warning device for an aircraft comprising first means for monitoring the deactivation of an autopilot of this aircraft and second means for activating the transmission of a sound alert in the cockpit.
- This device is remarkable in that said second means are able to activate the transmission of a first sound of duration between a first predetermined value and a second predetermined value, and then a second sound, when said first means detect a deactivation. autopilot.
- this sound alert device further comprises third means for acquiring an acknowledgment of said sound alert, said second means being able to cancel the emission of the second sound when the third means detect a sound. Acknowledgment of the audible alert.
- the invention also relates to an aircraft comprising an audible warning device as mentioned above.
- Figure 1 is a block diagram of a sound alert device according to the invention.
- FIG. 2 is a timing diagram illustrating the acoustic intensity I of a sound emitted in the cockpit of the aircraft, as a function of time t, during the emission of an audible alert following the deactivation of the autopilot.
- Figures 3 to 6 show timing similar to that of Figure 2, corresponding to different situations of acknowledgment of the sound alert.
- FIG. 7 represents a timing diagram similar to that of FIG. 2, corresponding to a variant of the invention.
- the device 1 for alerting an aircraft comprises first means 10 for monitoring the deactivation of an autopilot of this aircraft and second means 12 activation of the transmission of a sound alert in the cockpit.
- the first means 10 are connected to an autopilot 2 of the aircraft via a link 20.
- the autopilot 2 communicates its activated / deactivated state to these first means 10 via this link 20.
- This connection may for example be a digital data link.
- These first means 10 monitor the state of the autopilot and when they detect a transition from the activated state to the deactivated state, they inform the second means 12, for example by a link 22.
- these second means are connected by a connection 24 to means 18 for sound emission in the cockpit.
- the latter comprise at least one loudspeaker.
- the second means 12 maintain this first activated sound for a duration between a first predetermined value d1 and a second predetermined value d2.
- the second means 12 deactivate said first sound and activate the emission, by the means 18 of sound emission, of a second sound of acoustic intensity 12 greater than the acoustic intensity 11 of the first sound.
- the acoustic intensity values in the cockpit 11 and 12 are chosen so that a first acoustic intensity sound 11 is sufficiently audible in the cockpit with respect to the ambient noise present in this cockpit, without however disturbing the pilots, and in such a way that a second sound of acoustic intensity 12 attracts more attention from the pilots than the first sound, in order to incite them to react to the sound alert (by acknowledging this alert) by becoming aware of the deactivation autopilot.
- the audible warning device 1 further comprises third means 14 for acquiring information for acknowledging the audible warning.
- third means 14 are connected by a link 26 to means 16 for acknowledging this audible warning.
- These advantageously comprise a push button 17.
- this push button is located on the handle or on the mini-stick (depending on the type of aircraft) used to control the movements of the aircraft.
- the acknowledging means 16 then being also connected to said autopilot 2 by a link 30.
- the third means 14 detect a pressing on the pushbutton 17 means 16 for acknowledging, they send an acknowledgment information to the second means 12, for example by a link 28. If the second means receive this acknowledgment information while they are in a state in which they activate the transmission of a first or second sound, they take into account this acknowledgment information in order to disable the transmission of this sound as specified below:
- the second means 12 When the acknowledgment ACK of the audible warning occurs before the end of the duration d1, the second means 12 maintain the activation of said first sound until the end of this duration d1, then they deactivate this first sound, as shown in Figure 3. In this case, the emission of the second sound is not activated;
- the second means 12 deactivate the first sound substantially from the instant of this acknowledgment, as represented in FIG. 4. In this case, the transmission of the second sound is not activated;
- the second means 12 deactivate the emission of the first sound and activate the emission of a second sound from the end of the duration d2.
- the second means deactivate this second sound substantially from the moment of this acknowledgment
- this second sound is kept at a minimum for a third predetermined duration d3 from the end of the duration d2.
- the second means 12 maintain the activation of said second sound until the end of this duration d3, then they deactivate this second sound , as shown in FIG. 5.
- the acknowledgment ACK of the audible warning occurs after the end of the duration d3, the second means 12 deactivate this second sound substantially from the instant of this acknowledgment, as represented in FIG. .
- the first predetermined duration d1 is substantially equal to 400 ms
- the second predetermined duration d2 is substantially equal to 800 ms
- the third predetermined duration d3 is substantially equal to 400 ms.
- the value of the acoustic intensity corresponding to the second sound varies progressively from the value 11 of the acoustic intensity corresponding to the first sound (at a time corresponding to the duration d2) to a maximum value predetermined 12, as shown in Figure 7.
- the acknowledgment method is identical to that described above.
