Description

Technical Field

[0001] The present invention relates to the technical field of aircraft, and in particular, to a method, a system, an electronic device, a medium and a program for controlling the go-around of an aircraft. Background Art

[0002] New aircraft produced by current mainstream manufacturers all have the functions of soft go-around and full-thrust go-around. Soft go-around means providing a reduced-thrust go-around similar to reduced-thrust takeoff, and full-thrust go-around is to perform a go-around in the state of full thrust of the aircraft. When performing a go-around, some aircraft have a passive throttle control unit. For such aircraft to perform a go-around, the crew needs to set the thrust lever to the TO / GA (Take-Off / Go-Around) or Flex / MCT (Flexible Reduced Thrust / Maximum Continuous Thrust) position to activate the full-thrust go-around or soft go-around. Some aircraft use an active throttle control unit, which activates the soft go-around after the crew presses the TO / GA button for the first time and activates the full-thrust go-around after pressing the TO / GA button for the second time.

[0003] However, when an aircraft with an active throttle control unit performs a go-around, since it is necessary to activate the soft go-around after the crew presses the TO / GA button for the first time and activate the full-thrust go-around after pressing the TO / GA button for the second time, in the case of a need for a soft go-around, the soft go-around may be exited due to the crew accidentally touching the TO / GA button and cannot be entered again. Summary of the Invention

[0004] The present invention provides a method, a system, a device, a medium and a program for controlling the go-around of an aircraft, aiming to effectively solve the problem that when an aircraft with an active throttle control unit performs a go-around, pressing the TO / GA button for the first time can only activate the soft go-around mode, and it is necessary to press the button a second time to enter the full-thrust go-around. The present invention provides a way to automatically select soft go-around or full-thrust go-around. At the same time, it solves the technical problem that in the case of a need for a soft go-around, the soft go-around may be exited due to the crew accidentally touching the take-off / go-around button and cannot be entered again.

[0005] According to a first aspect of the present invention, there is provided a method for controlling the go-around of an aircraft, including: obtaining the flight state of the aircraft, and performing go-around preparation of the aircraft according to the flight state; monitoring the positions of the take-off / go-around button and the throttle lever of the aircraft, and performing a go-around based on the state of the take-off / go-around button and the position of the throttle lever.

[0006] Further, the step of performing a go-around based on the state of the takeoff / go-around button and the position of the throttle lever includes: during a go-around, if it is detected that the takeoff / go-around button is triggered, activate the guided go-around mode to perform a go-around of the aircraft; if it is not detected that the takeoff / go-around button is triggered and the throttle lever is pushed to the takeoff / go-around position, enter the unguided go-around to perform a go-around of the aircraft, where the guided go-around mode is used to guide the flight crew to operate the aircraft to perform a soft go-around or a full-thrust go-around, and the unguided go-around is for the flight crew to operate the aircraft to go around without guidance.

[0007] Further, when activating the guided go-around mode, the go-around steps of the aircraft include: determining whether the aircraft needs a soft go-around or a full-thrust go-around; if the aircraft needs a soft go-around, activate the soft go-around mode, display the first go-around guidance, and use the aircraft's automatic throttle system to adjust the thrust of the aircraft in the soft go-around mode; if the aircraft needs a full-thrust go-around, activate the full-thrust go-around mode, display the second go-around guidance, and use the aircraft's automatic throttle system to adjust the thrust of the aircraft to the full takeoff / go-around thrust.

[0008] Further, the step of determining whether the aircraft needs a soft go-around or a full-thrust go-around includes: using the flight state to determine whether the aircraft altitude is greater than a preset decision height; if it is not greater than the decision height, activate the full-thrust go-around mode until reaching the reduced-thrust altitude and end the go-around; if it is greater than the decision height, determine whether the aircraft altitude is more than 400 feet below the go-around target height; if it is not more than 400 feet below the target height, activate the soft go-around mode until reaching the reduced-thrust altitude and end the go-around; if it is more than 400 feet below the target height, determine whether all engines are operating; if not all engines are operating, activate the full-thrust go-around mode until reaching the acceleration altitude and end the go-around; if all engines are operating, activate the soft go-around mode until reaching the reduced-thrust altitude and end the go-around.

[0009] Further, the step of determining whether the aircraft needs a soft go-around or a full-thrust go-around also includes: after the step of if it is not more than 400 feet below the target height, activate the soft go-around mode, or if all engines are operating, activate the soft go-around mode, and before ending the go-around, determine whether a wind shear occurs; if a wind shear occurs, stop the soft go-around mode and activate the full-thrust go-around mode until reaching the reduced-thrust altitude and end the go-around; if no wind shear occurs, continue the soft go-around mode until the aircraft reaches the reduced-thrust altitude and end the go-around.

[0010] Further, the steps for determining whether the aircraft needs a soft go-around or a full-thrust go-around also include: if the altitude is not less than 400 feet above the target altitude, activate the soft go-around mode, or if all engines of the aircraft are operating, activate the soft go-around mode, and during the go-around process, determine whether the throttle lever is pushed to the takeoff / go-around position; if the throttle lever is pushed to the takeoff / go-around position, stop the soft go-around mode and activate the full-thrust go-around mode until the reduced-thrust altitude is reached and the go-around ends; if the throttle lever is not pushed to the takeoff / go-around position, continue the soft go-around mode until the aircraft reaches the reduced-thrust altitude and the go-around ends.

[0011] Further, when entering a non-guided go-around or transferring to a full-thrust go-around after the throttle lever is pushed to the takeoff / go-around position during the activation of the soft go-around, the go-around steps of the aircraft include: when the throttle lever is pushed to the takeoff / go-around position, after triggering the takeoff / go-around button again, determine whether the thrust of the aircraft is excessive; if so, activate the soft go-around mode, display the first go-around guidance, and use the aircraft's automatic throttle system to adjust the thrust of the aircraft in the soft go-around mode; if not, display the second go-around guidance.

[0012] Further, when activating the guided go-around mode, the go-around steps of the aircraft include: after the step of activating the soft go-around mode, determine whether a wind shear occurs; if a wind shear occurs, stop the soft go-around mode and activate the full-thrust go-around mode.

[0025] The following will combine the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work belong to the scope of protection of the present invention.

[0026] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the term "and / or" in this text is merely an association relationship describing associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this text generally represents an "or" relationship between the associated objects before and after without special instructions.

[0027] Aircraft operation experience shows that when all engines are operating, the maximum thrust is not required to meet the go-around climb gradient requirement. Moreover, the longitudinal acceleration caused by TO / GA thrust may cause the flight crew to experience "spatial disorientation illusion". Spatial disorientation illusion refers to the situation that when the aircraft accelerates rapidly, the stimulation generated by the acceleration on the otoliths of the human body is very similar to the stimulation generated by the head tilting backward, and people are prone to mistakenly think that the aircraft is in a nose-up (i.e., climbing) trend. Especially in the case of insufficient visual reference, the flight crew may cause the aircraft to enter a nose-down or diving attitude. Therefore, providing a reduced-thrust go-around (also known as a soft go-around) similar to a reduced-thrust takeoff can avoid the wrong operation caused by the "spatial disorientation illusion" of the flight crew while meeting the climb performance.

[0028] Different from the passive throttle quadrant that can activate the soft go-around by setting the thrust lever at different positions, the active throttle quadrant only has one way to activate the go-around by the TO / GA switch. How to allow the flight crew to clearly and conveniently select the soft go-around or the full-thrust go-around has become a problem that must be faced after adding the soft go-around.

[0029] New aircraft produced by current mainstream manufacturers all have the functions of soft go-around and full-thrust go-around. For some aircraft with a passive throttle quadrant, the flight crew sets the thrust lever to the TO / GA or Flex / MCT position to activate the full-thrust go-around or the soft go-around. For some aircraft with an active throttle quadrant, the soft go-around is activated after the first press of the TOGA button, and the full-thrust go-around is activated after the second press of the TOGA button.

[0030] However, for aircraft with a passive throttle quadrant, if a go-around is required, the flight crew needs to first set the thrust lever to the TO / GA position to activate the go-around guidance. If the soft go-around is needed, the thrust lever needs to be set to the Flex / MCT position again, increasing the operation steps of the flight crew.

[0031] For an aircraft with a manual throttle, the crew needs to press the TOGA button for the first time to activate a soft go-around, and press the TOGA button for the second time to activate a full-thrust go-around. This switching method depends on the crew's selection between a soft go-around and a full-thrust go-around, and may exit the soft go-around due to the crew accidentally touching the TOGA button. Moreover, on the FMA (Flight Mode Annunciator), the FD (Flight Director) mode shows TO / GA for both cases, and only the automatic throttle modes THR (Thrust) and THR REF (Thrust Reference) can be used to distinguish between the two go-around methods, providing unintuitive and unclear prompting information to the crew.

[0032] The embodiments of the present application provide a go-around control method, system, device, medium, and program for an aircraft, which can automatically identify entering a soft go-around or a full-thrust go-around, and can effectively solve the technical problems in the prior art that when an aircraft with a manual throttle performs a go-around, in the case of a need for a soft go-around, it may exit the soft go-around due to the crew accidentally touching the TOGA button, etc.

[0033] Figure 1 The following shows the go-around control method for an aircraft provided by the embodiments of the present invention, including:

[0034] S101. Obtain the flight state of the aircraft and perform go-around preparation for the aircraft according to the flight state.

[0035] S102. Monitor the positions of the takeoff / go-around button and the throttle lever of the aircraft, and perform a go-around based on the state of the takeoff / go-around button and the position of the throttle lever.

[0036] In some embodiments, in step S102, the step of performing a go-around based on the state of the takeoff / go-around button and the position of the throttle lever includes: during the go-around process, if it is monitored that the takeoff / go-around button is triggered, activate the guided go-around mode to perform a go-around for the aircraft; if it is not monitored that the takeoff / go-around button is triggered and the throttle lever is pushed to the takeoff / go-around position, enter the non-guided go-around to perform a go-around for the aircraft.

[0037] The go-around control method provided in this embodiment is applicable to an aircraft with a manual throttle. The control method can be deployed in the aircraft's automatic flight control system or in a separate flight control system.

[0038] In other embodiments, during the go-around execution based on the state of the takeoff / go-around button and the position of the throttle lever, if it is detected that the takeoff / go-around button is triggered for the first time, the guided go-around mode is activated for the go-around of the aircraft. If it is detected that the takeoff / go-around button is triggered for the second time, the original guided go-around mode is maintained or switched to the soft go-around mode. In this way, even if the crew accidentally touches the takeoff / go-around button, it can be ensured that the soft go-around can be activated again.

[0039] In steps S101 and S102, the flight state of the aircraft includes the aircraft's current decision height / altitude, radio altitude, barometric altitude, go-around target altitude, engine state, etc. Among them, as Figure 2 shown, the aircraft's automatic flight control system can obtain data such as the aircraft's decision height / altitude, TOGA switch state, engine state, etc. from the flight management system and the power system, and can obtain data such as the aircraft altitude from the air data and radio navigation system. When the automatic flight control system executes steps S101 - S102, after computer calculation, it will automatically complete the pitch guidance and thrust mode switching in the go-around phase, and display these data in the display system.

[0040] In this embodiment, the guided go-around mode is used to guide the crew to operate the aircraft to perform a soft go-around or a full-thrust go-around, and the non-guided go-around mode is for the crew to operate the aircraft to perform a non-guided go-around.

[0041] Therefore, the aircraft go-around control method provided in this embodiment can monitor in real time the positions of the TOGA button and the throttle lever, and can monitor whether the aircraft receives a go-around command, so that the go-around of the aircraft with an active throttle stand is not only controlled by the TOGA button, and this can prevent the situation where it is impossible to enter the soft go-around again.

[0042] In some embodiments, when the guided go-around mode is activated, the go-around steps of the aircraft include: determining whether the aircraft needs a soft go-around or a full-thrust go-around. If the aircraft needs a soft go-around, the soft go-around mode is activated, and the first go-around guidance is presented, and the thrust of the aircraft in the soft go-around mode is adjusted using the aircraft's automatic throttle system until the go-around ends. If the aircraft needs a full-thrust go-around, the full-thrust go-around mode is activated, and the second go-around guidance is presented, and the thrust of the aircraft is adjusted to the full takeoff / go-around thrust using the aircraft's automatic throttle system until the go-around ends.

[0043] In this embodiment, the guided go-around mode can present the first go-around guidance, that is, the presented first go-around guidance is the go-around guidance in the activated soft go-around state, and can also present the second go-around guidance, that is, the presented second go-around guidance is the go-around guidance in the activated full-thrust go-around state, and under the activated corresponding go-around mode, the thrust of the aircraft is adjusted so that the aircraft can enter the soft go-around mode or the full-thrust go-around mode.

[0044] In some embodiments, the steps of determining whether an aircraft needs a soft go-around or a full-thrust go-around include: using the flight state to determine whether the aircraft altitude is greater than a preset decision altitude; if it is not greater than the decision altitude, activate the full-thrust go-around mode until the reduced-thrust altitude is reached and end the go-around; if it is greater than the decision altitude, determine whether the aircraft altitude is more than 400 feet below the target altitude of the go-around; if it is not more than 400 feet below the target altitude, activate the soft go-around mode until the reduced-thrust altitude is reached and end the go-around; if it is more than 400 feet below the target altitude, determine whether all engines are operating; if not all engines are operating, activate the full-thrust go-around mode until the acceleration altitude is reached and end the go-around; if all engines are operating, activate the soft go-around mode until the reduced-thrust altitude is reached and end the go-around.

[0045] In this embodiment, if the aircraft is not greater than the decision altitude, the aircraft needs to perform a full-thrust go-around. If the aircraft is greater than the decision altitude and the aircraft altitude is not more than 400 feet below the target altitude of the go-around, the aircraft needs to enter the soft go-around mode. If the aircraft is greater than the decision altitude, the aircraft altitude is below the target altitude of the go-around, and not all engines are operating, activate the full-thrust go-around mode until the acceleration altitude is reached and then end the go-around. If the aircraft is greater than the decision altitude, the aircraft altitude is below the target altitude of the go-around, and all engines are operating, activate the soft go-around mode until the aircraft reaches the reduced-thrust altitude and then end the go-around.

[0046] In some embodiments, the steps of determining whether an aircraft needs a soft go-around or a full-thrust go-around further include: after the step of activating the soft go-around mode if it is not more than 400 feet below the target altitude or activating the soft go-around mode if all engines are operating, and before ending the go-around, determine whether wind shear occurs; if wind shear occurs, stop the soft go-around mode and activate the full-thrust go-around mode until the reduced-thrust altitude is reached and end the go-around; if wind shear does not occur, continue the soft go-around mode until the aircraft reaches the reduced-thrust altitude and end the go-around.

[0047] In this embodiment, if wind shear occurs during the soft go-around of the aircraft, stop the soft go-around and activate the full-thrust go-around so that the aircraft can cope with the situation of wind shear.

[0048] In some embodiments, the steps of determining whether a soft go-around or a full-thrust go-around is required for an aircraft further include: if the altitude is not less than 400 feet above the target altitude, activate the soft go-around mode, or if all engines of the aircraft are operating, activate the soft go-around mode, and while the go-around has not ended, determine whether the throttle lever is pushed to the takeoff / go-around position; if the throttle lever is pushed to the takeoff / go-around position, stop the soft go-around mode and activate the full-thrust go-around mode until the reduced-thrust altitude is reached, ending the go-around; if the throttle lever is not pushed to the TOGA position, continue the soft go-around mode until the aircraft reaches the reduced-thrust altitude, ending the go-around.

[0049] In this embodiment, if during the soft go-around of the aircraft, the throttle lever is pushed to TOGA, it means that the flight crew needs to control the engines of the aircraft to operate at full power. At this time, it is necessary to activate the full-thrust go-around mode until the reduced-thrust altitude is reached, ending the go-around.

[0050] In some embodiments, when entering the non-guided go-around mode or when the throttle lever is pushed to the takeoff / go-around position after the soft go-around is activated and then switches to the full-thrust go-around mode, the go-around steps of the aircraft include: when the throttle lever is pushed to the takeoff / go-around position, after triggering the takeoff / go-around button again, determine whether the thrust of the aircraft is excessive; if so, activate the soft go-around mode, display the first go-around guidance, and use the automatic throttle system of the aircraft to adjust the thrust of the aircraft in the soft go-around mode; if not, display the second go-around guidance.

[0051] In addition, if the flight crew does not press the TOGA button to activate the soft go-around mode at the initial moment, and the instinctive operation of the flight crew is to push the throttle lever to the TOGA position, once a positive climb is established, if thrust reduction is required at this time, it is still possible to switch from the full-thrust go-around to the soft go-around by pressing the TOGA button.

[0052] In this embodiment, when the throttle lever is pushed to the TOGA position, it means that the engines of the aircraft are operating at full power. At this time, there may be a situation of excessive thrust, which will cause a decrease in comfort and fuel waste. Activating the soft go-around mode at this time can reduce the power of the engines, adjust the thrust of the aircraft, and display the first go-around guidance, enabling the flight crew to clearly know the state of the aircraft at this time and the operations required, etc.

[0053] In some embodiments, when activating the guided go-around mode, the go-around steps of the aircraft include: after the step of activating the soft go-around mode, determine whether a wind shear occurs; if a wind shear occurs, stop the soft go-around mode and activate the full-thrust go-around mode.

[0054] In this embodiment, in the guided go-around mode, if a wind shear occurs, directly activate the full-thrust go-around mode so that the aircraft can cope with the wind shear situation.

[0055] Therefore, the aircraft go-around control method provided by the embodiments of the present application can determine whether to use reduced thrust go-around (soft go-around) or full thrust go-around based on the engine state, decision height, and go-around altitude target. By switching the pitch mode and thrust mode and coordinating with the change of FMA information, the crew can clearly and conveniently execute the go-around under the active throttle stand architecture, reducing the crew load during the go-around phase. Usually, the soft go-around can be automatically executed, reducing the full thrust usage cycles of the engine and extending the service life of the engine.

[0056] Please refer to Figure 3 , the embodiments of the present application further include an aircraft go-around control system, including: a go-around preparation module 1 and a go-around module 2; the go-around preparation module 1 is used to obtain the flight state of the aircraft and perform the go-around preparation of the aircraft according to the flight state; the go-around module 2 is used to monitor the positions of the takeoff / go-around button and the throttle lever of the aircraft, and perform the go-around based on the state of the takeoff / go-around button and the position of the throttle lever.

[0057] Among them, when the go-around module 2 performs the go-around based on the state of the takeoff / go-around button and the position of the throttle lever, it is used to, during the go-around process, if it monitors that the takeoff / go-around button is triggered, activate the guided go-around mode to perform the go-around of the aircraft until the go-around ends; if it does not monitor that the takeoff / go-around button is triggered and the throttle lever is pushed to the takeoff / go-around position, enter the unguided go-around to perform the go-around of the aircraft until the go-around ends. Among them, the guided go-around mode is used to guide the crew to operate the aircraft to perform a soft go-around or a full thrust go-around, and the unguided go-around mode is for the crew to operate the aircraft to perform the go-around without guidance.

[0058] The aircraft go-around control system provided by this embodiment can monitor the positions of the TOGA button and the throttle lever in real time, and can monitor whether the aircraft receives the go-around instruction, so that the go-around of the aircraft with an active throttle stand is not only controlled by the TOGA button, and this will not result in the situation where it is impossible to enter the soft go-around again.

[0061] In some embodiments, the first judgment unit further includes: a wind shear switching unit, configured to judge whether wind shear occurs after the step of activating the soft go-around mode if it is not less than 400 feet above the target height, or activating the soft go-around mode if all engines are operating, and before ending the go-around; if wind shear occurs, stop the soft go-around mode and activate the full thrust go-around mode until the reduced thrust height is reached and end the go-around; if wind shear does not occur, continue the soft go-around mode until the aircraft reaches the reduced thrust height and end the go-around.

[0062] In some embodiments, the first judgment unit further includes: a throttle lever monitoring and execution unit, configured to judge whether the throttle lever is pushed to the takeoff / go-around position after activating the soft go-around mode if it is not less than 400 feet above the target height, or activating the soft go-around mode if all engines are operating, and before ending the go-around; if the throttle lever is pushed to the takeoff / go-around position, stop the soft go-around mode and activate the full thrust go-around mode until the reduced thrust height is reached and end the go-around; if the throttle lever is not pushed to the takeoff / go-around position, continue the soft go-around mode until the aircraft reaches the reduced thrust height and end the go-around.
