Description

Technical Field

[0001] This invention relates to a takeoff unsafe configuration warning system for aircraft, addressing whether numerous systems on the aircraft are in a safe takeoff configuration during the initial stage of takeoff. This invention belongs to the field of avionics system design. This invention also relates to a method for providing takeoff unsafe configuration warnings for aircraft. Background Technology

[0002] Before each takeoff, the flight crew needs to correctly configure the numerous systems on the aircraft so that all systems are in takeoff configuration.

[0003] To avoid oversights, flight crews typically use checklists to ensure all systems are in the correct takeoff configuration. However, even following the checklist process, human error can still cause aircraft systems to be misconfigured, preventing safe takeoff. To mitigate such incidents, regulations require the installation of unsafe takeoff configuration warning systems (USMCs) to provide the flight crew with warnings of unsafe configurations during the initial takeoff phase (runway roll).

[0004] Different aircraft models (including their derivatives) have different takeoff configuration requirements. Currently, the threshold for takeoff configuration warnings needs to be adaptively modified according to the current aircraft model to meet the safe takeoff requirements of the current model. However, this requires different hardware and software for the corresponding takeoff configuration warning system for different aircraft models.

[0005] When the unsafe takeoff configuration warning system itself malfunctions, it may cause the aircraft to be in an unsafe takeoff configuration but fail to report the problem. In such cases, the unsafe takeoff configuration warning system itself should be alerted, and if the system fails, the pilot should be notified. Summary of the Invention

[0006] To address the aforementioned problems in the prior art, the inventors provide a universal takeoff unsafe configuration warning system to support the requirements for safe takeoff.

[0007] In a first example of the unsafe takeoff configuration warning system, the system includes: an initial takeoff phase judgment module configured to adjust judgment thresholds for at least one initial takeoff phase parameter based on a received aircraft type signal, and to selectively issue a corresponding initial takeoff phase judgment signal based on whether the received initial takeoff phase parameter meets the corresponding judgment threshold; an unsafe takeoff configuration judgment module configured to adjust judgment thresholds for at least one unsafe takeoff configuration parameter based on a received aircraft type signal, and to selectively issue a corresponding unsafe takeoff configuration judgment signal based on whether the at least one unsafe takeoff configuration parameter meets the corresponding judgment threshold; and an unsafe configuration alarm module communicatively connected to both the initial takeoff phase judgment module and the unsafe takeoff configuration judgment module, and configured to selectively issue a corresponding unsafe configuration alarm signal based on the received initial takeoff phase judgment signal and the unsafe takeoff configuration judgment signal.

[0008] Based on the above configuration, the same system can be adapted to different aircraft models, thereby reducing the types and quantities of spare parts for airlines.

[0009] In addition, by determining whether the aircraft is in the initial takeoff phase, false alarms before the takeoff phase can be avoided, as well as interference with the crew in the later stages of the takeoff phase.

[0010] In a second example of the unsafe configuration warning system for takeoff, the first example may be optionally included, wherein the initial takeoff phase parameters include at least one of the following: throttle lever angle, airspeed, wheel load, wheel speed, engine speed, and radio altitude.

[0011] Based on the above configuration, it is possible to determine whether the aircraft is in the initial takeoff phase.

[0012] In the third example of the unsafe takeoff configuration warning system, one or more of the above examples may be optionally included, and the unsafe takeoff configuration parameters include at least one of the following: flap angle, slat angle, horizontal stabilizer angle, rudder trim angle, spoiler handle position, parking brake status, and the door status of each cabin door.

[0013] Based on the above configuration, it is possible to determine whether an aircraft is in an unsafe takeoff configuration.

[0014] In a fourth example of the unsafe configuration warning system for takeoff, one or more of the examples above may be included, and the unsafe configuration warning signal may include a visual warning signal and / or an auditory warning signal.

[0015] Based on the configuration described above, it can issue warnings to the crew.

[0016] In the fifth example of the unsafe takeoff configuration warning system, one or more of the above examples may be optionally included, wherein the unsafe configuration warning signal provides different visual and / or auditory warning signals for specific unsafe configurations based on the different unsafe takeoff configuration judgment signals.

[0017] Based on the above configuration, it can inform the crew members which specific configuration of the aircraft is not in place.

[0018] In the sixth example of the unsafe configuration warning system for takeoff, one or more of the above examples may be optionally included, wherein the unsafe configuration warning signal includes a preset risk level, and the unsafe configuration warning signal selectively emits visual warning signals of different colors and / or auditory warning signals of different sounds based on the preset risk level.

[0019] Based on the above configuration, different colors of visual warning signals and different sounds of auditory warning signals are issued according to the different danger levels of unsafe takeoff configuration parameters, which can simplify the crew's judgment of warnings of unsafe takeoff configuration parameters.

[0020] In the seventh example of the unsafe configuration warning system, one or more of the above examples may be included, where the unsafe configuration warning signal cannot be manually suppressed by the crew.

[0021] As described above, this configuration can prevent the unit from unintentionally or habitually shutting off alarm signals.

[0022] In the eighth example of the unsafe takeoff configuration warning system, one or more of the above examples may be included, wherein the fault indication module is communicatively connected to both the initial takeoff phase judgment module and the unsafe takeoff configuration judgment module, and is configured to selectively issue corresponding fault information based on the received initial takeoff phase judgment signal and unsafe takeoff configuration judgment signal.

[0023] As described above, when the Takeoff Unsafe Configuration Warning System malfunctions, a fault message must be set so that the crew is aware that the system is not operational. This system will send a fault signal through the signal network, display the fault information in the cockpit, and inform the crew of the specific fault.

[0024] The inventors also provide a method for warning of unsafe takeoff configurations for aircraft, supporting the requirements for safe takeoff.

[0025] In a first example of the unsafe takeoff configuration warning method, the method includes: an initial takeoff phase judgment module adjusting judgment thresholds for at least one initial takeoff phase parameter based on received aircraft type signals; and selectively issuing corresponding initial takeoff phase judgment signals based on whether the received initial takeoff phase parameters meet the corresponding judgment thresholds. Specifically, when each of the received at least one initial takeoff phase parameters meets the corresponding judgment threshold, the initial takeoff phase judgment signal indicates that the aircraft is in the initial takeoff phase; when any of the received at least one initial takeoff phase parameters does not meet the corresponding judgment threshold, the initial takeoff phase judgment signal indicates that the aircraft is not in the initial takeoff phase. The unsafe takeoff configuration judgment module adjusts the judgment thresholds for at least one unsafe takeoff configuration parameter based on the received aircraft type signals, to... The system selectively issues corresponding unsafe takeoff configuration judgment signals based on whether the received unsafe takeoff configuration parameters meet the corresponding judgment thresholds. When each of the received at least one unsafe takeoff configuration parameters meets the corresponding judgment threshold, the unsafe takeoff configuration judgment signal indicates that the aircraft is not in an unsafe takeoff configuration. When any of the received at least one unsafe takeoff configuration parameters does not meet the corresponding judgment threshold, the unsafe takeoff configuration judgment signal indicates that the aircraft is in an unsafe takeoff configuration. The unsafe configuration alarm module selectively issues corresponding unsafe configuration alarm signals based on the initial takeoff phase judgment signal and the unsafe takeoff configuration judgment signal. When the initial takeoff phase judgment signal indicates that the aircraft is in the initial takeoff phase, and the unsafe takeoff configuration judgment signal indicates that the aircraft is in an unsafe takeoff configuration, an unsafe configuration alarm signal is issued.

[0026] In a second example of the unsafe takeoff configuration warning method, the above example may be optionally included. The fault indication module selectively issues corresponding fault information based on the initial takeoff phase judgment signal and the unsafe takeoff configuration judgment signal. The fault information is issued when any one of the initial takeoff phase parameters and unsafe takeoff configuration parameters obtained from the corresponding source is invalid, missing, or incorrect, or when any one of the initial takeoff phase judgment module, unsafe takeoff configuration judgment module, and unsafe configuration alarm module malfunctions or is shut down.

[0027] The unsafe takeoff configuration warning system of this invention can automatically adjust the alarm threshold according to different derivative aircraft models, enabling the same system to be installed on different derivative aircraft models. This adapts to various aircraft models, thereby reducing the types and quantities of spare parts for airlines.

[0028] This system uses signals such as throttle lever angle, airspeed, wheel load, wheel speed, engine speed, and radio altitude to determine whether the aircraft is in the initial takeoff phase. This can avoid false alarms before entering the takeoff phase and interference to the crew in the later stages of the takeoff phase. Attached Figure Description

[0051] Finally, the numerical values ​​given in the various embodiments are merely examples and are not intended to limit the scope of the invention.

[0052] The unsafe takeoff configuration warning system 1 for aircraft of the present invention generally includes an initial takeoff phase judgment module 10, an unsafe takeoff configuration judgment module 20, and an unsafe configuration alarm module 30. In this invention, several different embodiments of the unsafe takeoff configuration warning system having the above structure will be provided, which will be described in detail below with reference to the accompanying drawings.

[0053] (Example 1)

[0054] Figure 1 This is a schematic diagram of a takeoff unsafe configuration warning system according to an embodiment of the present invention.

[0055] In one embodiment of the present invention, the unsafe takeoff configuration warning system 1 includes an initial takeoff phase judgment module 10, an unsafe takeoff configuration judgment module 20, and an unsafe configuration alarm module 30.

[0056] The initial takeoff phase determination module 10 receives the aircraft type signal a0 and at least one initial takeoff phase parameter a1 to determine whether the aircraft is in the initial takeoff phase, and selectively sends the corresponding initial takeoff phase determination signal b1.

[0057] The aircraft type signal a0 is used to identify the aircraft type, whether it is manually entered or automatically identified.

[0058] Initial takeoff phase parameter a1 may include at least one of the parameters used to determine the initial takeoff phase of the aircraft: throttle lever angle, airspeed, wheel load, wheel speed, engine speed, and radio altitude, etc., from numerous systems on the corresponding aircraft. For example, Figure 1 As shown, the throttle lever angle comes from the engine system ( Figure 1 Taking a twin-engine aircraft as an example, the throttle lever angles of the left and right engines can be provided separately; the airspeed signal comes from the air data system; and the wheel load signal comes from the landing gear system.

[0059] The initial takeoff phase determination module 10 adjusts the determination threshold for at least one initial takeoff phase parameter a1 based on the received aircraft type signal a0. For example, based on the aircraft type signal a0, the thrust requirement for takeoff is determined, and the required number of initial takeoff phase parameters a1 are selected as the initial takeoff phase determination conditions: combining the throttle lever angle signal (specifically the minimum takeoff throttle lever angle value), wheel load signal, and airspeed signal, it is determined whether the aircraft is simultaneously on the ground and the airspeed is less than V1, thereby determining whether the aircraft is in the initial takeoff phase, and issuing the corresponding initial takeoff phase determination signal b1.

[0060] The unsafe takeoff configuration judgment module 20 receives the aircraft type signal a0 and at least one unsafe takeoff configuration parameter a2 to determine which systems on the aircraft have unsafe configurations, and selectively sends out the corresponding unsafe takeoff configuration judgment signal b2.

[0061] Unsafe takeoff configuration parameter a2 may include at least one of the parameters used to determine the initial takeoff phase of the aircraft: flap angle, slat angle, horizontal stabilizer angle, rudder trim angle, spoiler handle position, parking brake status, and door status of each compartment, etc., derived from numerous systems on the corresponding aircraft. For example, Figure 1 As shown, the flap angle and slat angle come from the high-lift system; the horizontal stabilizer angle, rudder trim angle, and spoiler handle position come from the main flight control system; the parking brake status comes from the braking system; and the door status of each compartment comes from the door system.

[0062] The unsafe takeoff configuration judgment module 20 adjusts the judgment threshold for at least one unsafe takeoff configuration parameter a2 based on the received aircraft type signal a0. For example, it compares these unsafe takeoff configuration parameters a2 one by one with the corresponding parameters in the takeoff configuration required for that type of aircraft to determine whether the aircraft is in a safe takeoff configuration state and issues the corresponding unsafe takeoff configuration judgment signal b2.

[0063] The unsafe configuration alarm module 30 is communicatively connected to both the initial takeoff phase judgment module 10 and the unsafe takeoff configuration judgment module 20. It receives the initial takeoff phase judgment signal b1 and the unsafe takeoff configuration judgment signal b2, and selectively issues an unsafe configuration alarm signal c1, indicating whether the aircraft has an unsafe configuration or which systems on the aircraft exhibit an unsafe configuration. The unsafe configuration alarm module 30 may include visual alarm signals and / or auditory alarm signals.

[0064] Preferably, the unsafe configuration warning signal c1 can provide different visual and / or auditory warning signals for specific unsafe configurations based on the different unsafe takeoff configuration judgment signals b2, thereby informing the crew which specific configuration of the aircraft is not in place. For example, when the aircraft is in the initial takeoff phase and one or more configurations of the aircraft have not reached the safe takeoff configuration state, this system will issue an alarm signal through the signal network, triggering an audible and visual alarm in the cockpit (red warning characters, flashing red warning lights, and a continuous alarm sound). The warning characters can specifically indicate which configuration is incorrect (e.g., incorrect rudder trim angle), the warning lights can stop flashing after crew confirmation, and the alarm sound cannot be suppressed by the crew until the alarm conditions are no longer met.

[0065] Preferably, the unsafe configuration alarm module 30 can have preset risk levels. For example, if the unsafe takeoff configuration judgment signal b2 indicates that one parameter has an unsafe problem, the risk level is low risk; if it indicates that three or more parameters have unsafe problems, the risk level is high risk. Furthermore, the unsafe configuration alarm signal c1 can selectively emit visual alarm signals of different colors and / or auditory alarm signals of different sounds based on the preset risk level, thereby alerting the crew to the degree of risk of the aircraft's unsafe configuration.

[0066] Preferably, the unsafe configuration alarm signal cannot be manually suppressed by the unit, thereby preventing the unit from unintentionally or habitually shutting down the alarm signal.

[0067] (Example 2)

[0068] Figure 2 This is a schematic diagram of a takeoff unsafe configuration warning system according to another embodiment of the present invention.

[0069] In Embodiment 2, the unsafe takeoff configuration warning system 1 includes an initial takeoff phase judgment module 10, an unsafe takeoff configuration judgment module 20, an unsafe configuration alarm module 30, and a fault indication module 40. For the sake of brevity, identical modules will not be described again.

[0070] The fault indication module 40 is communicatively connected to both the initial takeoff phase judgment module 10 and the unsafe takeoff configuration judgment module 20, and receives the initial takeoff phase judgment signal b1 and the unsafe takeoff configuration judgment signal b2, and is used to selectively issue fault information c2.

[0071] For example, if the system cannot obtain the signals or signals of the parameters required for the calculation of the initial takeoff phase and unsafe takeoff configuration from the corresponding systems among the many systems on the aircraft, such as an invalid, lost or incorrect spoiler handle position signal, or if the system itself malfunctions, causing some or all functional modules to be inactive, thus affecting the calculation of the unsafe takeoff configuration alarm and preventing the calculation of the correct result, the system can send a fault signal through the signal network, display the fault information in the cockpit, and inform the crew of the specific fault situation, such as: the parking brake configuration warning is not working, the takeoff configuration warning system is not working, allowing the crew to decide on the next action based on the current situation.

[0072] The present invention also relates to a method for warning of unsafe takeoff configurations of an aircraft.

[0073] Figure 3 This is a flowchart of a takeoff unsafe configuration warning method according to an embodiment of the present invention.

[0074] The initial takeoff phase determination module 10 adjusts the determination threshold for at least one initial takeoff phase parameter a1 based on the received aircraft type signal a0, and selectively issues an initial takeoff phase determination signal b1 based on whether the received initial takeoff phase parameter a1 meets the corresponding determination threshold.

[0075] This is an AND gate, meaning that when each of the at least one initial takeoff phase parameter a1 received satisfies the corresponding judgment threshold, the initial takeoff phase judgment signal b1 sends a judgment signal indicating that the aircraft is in the initial takeoff phase; when any of the at least one initial takeoff phase parameter a1 received does not satisfy the corresponding judgment threshold, the initial takeoff phase judgment signal b1 sends a judgment signal indicating that the aircraft is not in the initial takeoff phase.

[0076] Meanwhile, the unsafe takeoff configuration judgment module 20 adjusts the judgment threshold for at least one unsafe takeoff configuration parameter a2 based on the received aircraft type signal a0, and selectively issues an unsafe takeoff configuration judgment signal b2 based on whether the received unsafe takeoff configuration parameter a2 meets the corresponding judgment threshold.

[0077] This is an "OR" gate, meaning that when each of the at least one unsafe takeoff configuration parameter a2 received satisfies the corresponding judgment threshold, the unsafe takeoff configuration judgment signal b2 is issued indicating that the aircraft is not in an unsafe takeoff configuration; when any of the at least one unsafe takeoff configuration parameter a2 received does not satisfy the corresponding judgment threshold, the unsafe takeoff configuration judgment signal b2 is issued indicating that the aircraft is in an unsafe takeoff configuration.

[0078] Subsequently, the unsafe configuration alarm module 30 selectively issues an unsafe configuration alarm signal c1 based on the initial takeoff phase judgment signal b1 and the unsafe takeoff configuration judgment signal b2.

[0079] This is an AND gate, meaning that when the initial takeoff phase judgment signal b1 indicates that the aircraft is in the initial takeoff phase, and the unsafe takeoff configuration judgment signal b2 indicates that the aircraft is in an unsafe takeoff configuration, an unsafe configuration warning signal c1 is issued.

[0080] In an embodiment not shown, the fault indication module 40 selectively issues fault information c2 based on the initial takeoff phase judgment signal b1 and the unsafe takeoff configuration judgment signal b2. Fault information c2 is issued when any one of the initial takeoff phase parameter a1 and the unsafe takeoff configuration parameter a2 obtained from the corresponding source becomes invalid, is missing, or is incorrect; or when any one of the initial takeoff phase judgment module 10, the unsafe takeoff configuration judgment module 20, and the unsafe configuration alarm module 30 malfunctions or is shut down.

[0081] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention have been clearly and completely described above in conjunction with the specific embodiments and accompanying drawings.

[0082] Although various embodiments have been described above, it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of them, and are presented by way of example rather than limitation. It will be apparent to those skilled in the art that the disclosed subject matter may be implemented in other specific forms without departing from its spirit and essential characteristics.
