Problems solved by technology

However, if the compass does not have a scale associated with it, the frustum line is less useful and may obstruct or conflict with other symbols displayed inside the compass
For example, adding a frustum line may cause difficulties not only in identifying the frustum line when the compass area contains a lateral deviation symbology for both the current and equipped Nav modes, and may hinder the reading of navigation information
Furthermore, simple frustum lines do not adequately provide awareness of large differences between current track and heading conditions

Abstract

A system and method displays a synthetic vision system (SVS) image combined with a primary flight display (PFD) including a compass indicating the aircraft heading. An arc on or near the outer edge of the compass indicates the viewing frustum of the SVS view.

Description

technical field [0001] The exemplary embodiments described herein relate generally to aircraft displays, and more particularly to helicopter Synthetic Vision System (SVS) displays. Background technique [0002] Occasionally, an aircraft may have a flight path that differs from its heading, such as when landing in a crosswind. Helicopter flight differs from fixed-wing aircraft due to significantly more vertical and lateral movement and dynamics, including that the flight path is often quite different from the helicopter's heading. [0003] When the SVS image is displayed on the primary flight display (PFD) and the SVS view may be centered at an angle different from the heading, the pilot needs to be able to quickly correlate the displayed SVS view with the information in the compass. The compass is usually centered on the heading to associate and fly according to the heading instructions from ATC. As such, representing the current flight path direction as, for example, a fl...
