Definitions

• the invention relates to a method for controlling a sensor in a combat aircraft.
• Document EP 1688698 Al describes a method which involves determining a drift according to environment data of a sensor, a communication unit and/or an arm system carried by a vehicle A mapping software is implemented to display on a screen a terrain zone around a schematic representation of the vehicle. A surface or a curve appears on the screen to display the drift of the sensor, the communication unit, the arm system and/or the detectability of the vehicle.
• HMI human machine interface
• decision support as supporting functions for the pilot environment in combat aircraft are known. All solutions are based on and adapted for high speed in flight and combat situations in which HMI and decision support together describe the current position and provide the pilot with tools and solutions. Current solutions are based on the aircraft itself and its available resources and tools. Sensors, such as radar, are operated by the pilot as a tool for scanning the near field for objects for the purpose of identification and continued pursuit. Decision support typically supports the multi-use of sensors by merging objects detected by several different sensors and comparing, correlating and/or combining these objects in one situation overview. This is usually done via networks in further steps to create a common situation overview between aircraft within an aircraft group.
