ATPL EASA Radio Navigation Practice Exam

The EHSI (Electronic Horizontal Situation Indicator) display is primarily designed to provide critical navigational information for pilots. The essential information that is displayed includes heading, course, and distance to waypoints. This data is crucial for maintaining situational awareness during flight, allowing pilots to effectively manage their navigation and ensure they are on the correct flight path.

The heading indicates the direction in which the aircraft is currently flying, while the course shows the intended path over the ground. The distance to waypoints aids pilots in understanding how far they are from their next navigational point, allowing them to plan their maneuvering and timing more accurately.

In contrast, while air temperature and humidity are important for many aspects of flight, they are not primary information displayed on the EHSI. Flight radar location of nearby aircraft is typically shown on a different display, such as the Traffic Collision Avoidance System (TCAS) or a multi-function display (MFD), rather than the EHSI. Visual landmarks may assist in pilot navigation visually but are not integral to the EHSI's electronic presentation of navigational data. Thus, the information presented by the EHSI is focused on aiding in navigation, making the inclusion of heading, course, and distance to waypoints
