Abstract:
A selected hover altitude deviation display in an aircraft having a multi-functional display unit that includes a compass rose and an aircraft symbol, the selected hover altitude deviation display comprising:an altitude sensor for generating raw data signals representing status information of current altitude of the aircraft with respect to an external environment of the aircraft, anda computer processing unit for defining the spatial location and perspective of the multi-functional display unit based upon the signals generated by the altitude sensor, the computer processing unit being operative to generate a combined analog/digital hover altitude deviation display that provides visual representations regarding the current altitude of the aircraft with respect to a selected hover altitude, the analog/digital hover altitude deviation display comprising:a static, analog symbolic representation of the selected hover altitude displayed on the multi-functional display unit, anda dynamic, analog symbolic representation of the difference between the current altitude of the aircraft and the selected hover altitude, the analog/digital hover altitude deviation display disposed on the multi-functional display unit to provide a visual indication of the spatial location of the aircraft with respect to the selected hover altitude indicated on the multi-functional display unit.
