Description

[001] This invention relates to a display device for an aircraft cockpit, which includes: - at least one first dedicated display area intended to be placed in front of a first cockpit seat; - at least one second dedicated display area intended to be placed in front of a second cockpit seat; - a display management assembly, configured to display in the first dedicated display area and in the second dedicated display area at least one aircraft flight parameter and/or at least one aircraft navigation and/or guidance parameter and/or at least one aircraft maintenance parameter; the display management assembly is configured to receive alert information from a central avionics unit and to display in at least one of the first dedicated display area and the second dedicated display area, at least one alert indication corresponding to a received alert information. [002] This display device, placed in the cockpit of an aircraft, is intended to improve coordination among the aircraft crew, especially during the aircraft's flight phases, in which the crew are subject to high demands. [003] Traditionally, piloting, navigation, communication and management of aircraft systems are ensured by two crew members who divide the various tasks. [004] A first crew member is dedicated, for example, to piloting and monitoring flight parameters, while a second crew member ensures ground communications, aircraft systems management, surveillance activities and other tasks not directly related to piloting. [005] To assist crew members in piloting the aircraft, each has a dedicated display area in front of their seat that indicates, for example, altitude, horizontal position, airspeed, vertical speed, as well as information about the engine, aircraft takeoff and landing settings and/or aircraft guidance parameters, especially during an approach. [006] The different indicators displayed in each dedicated display area are generally the same for each pilot. However, at least some of these indicators are developed from different sensors and/or sources to ensure measurement redundancy. This allows for the detection of potentially erroneous measurements from a faulty sensor or source and prevents them from being used in the display of both areas. [007] For example, during an aircraft's approach to a runway, guidance systems may be used to guide the aircraft to the runway. These guidance systems comprise, for example, an instrument landing system or "ILS", which requires that the beam from the ground station near the runway be detected. [008] The aircraft is equipped with at least two guidance receivers (also called "guidance sensor" or "guidance source"), each receiver intended to be used by a respective pilot when both receivers are functioning. [009] During an instrument approach to the runway, both the in-flight pilot and the non-in-flight pilot detect the ground station beam via distinct paths using a separate receiver to independently follow the runway guidance in their dedicated display area. The two aircraft receivers are configured to detect the same ground station when tuned to the ILS frequency. [010] The guidance instructions presented to each pilot are constructed based on what is detected by the respective receiver used by the pilot, translated into lateral and vertical deviation information. [011] In the event that the pilot loses approach guidance, for example, due to a failure of the receiver allocated to his approach side, a warning indicator is displayed in the pilot's dedicated in-flight display area and is accompanied by an audible alert to signal the loss of approach capability. [012] The pilot in flight must then abort the approach and no longer use the defective receiver and replace it with the other receiver or choose another approach category, for example, visual. [013] In existing display devices, if the pilot not in flight loses approach guidance, a warning indicator of the same level as that dedicated to the pilot in flight is also displayed in their dedicated display area, and the same audible alert is generally emitted as that applied to the pilot in flight. [014] However, the loss by the pilot not in flight of his allocated receiver generally does not require an interruption of the landing, as long as the pilot in flight still detects the guidance receiver that they are following. [015] In theory, the pilot in flight may continue the landing despite the alarm indications presented to the pilot not in flight and despite the audible alert transmitted in the cockpit. [016] In practice, the presence of a warning indication in the pilot's dedicated non-flight display area, coupled with an audible indication in the cockpit, may disturb the pilot in flight and lead him to cancel the landing as a precaution, even if the cause of the warning does not justify it. [017] One goal of the invention is therefore to provide a display device for the cockpit of an aircraft that enhances coordination among crew members and reduces
