Abstract
A selected hover altitude deviation display and method for displaying the difference between the current altitude of an aircraft and a selected hover altitude on a multi-functional display unit that includes a compass rose and an aircraft symbol. An altitude sensor generates current altitude data, which is transmitted to a computer processing unit together with a selected hover altitude. The selected hover altitude is determined by the pilot of the aircraft. The selected hover altitude is displayed as a static, analog symbolic representation on the multi-functional display unit. The hover altitude deviation is displayed as a dynamic, analog symbolic representation of the difference between the current altitude of the aircraft and the selected hover altitude. With the selected hover altitude deviation display, the pilot can readily see if his aircraft is above or below a selected hover altitude without relying on external visual reference cues.
