The EHSI displays a rotating compass scale divided into what increments?

The correct answer is based on how the Electronic Horizontal Situation Indicator (EHSI) presents navigational information to the pilot. The EHSI features a rotating compass scale that is crucial for orientation and navigation during flight. On this display, the compass scale is divided into increments of 5 and 10 degrees.

The use of 5-degree increments allows for fine adjustments and precise heading information, which is especially important for navigation and course tracking. The additional 10-degree increments help to visually separate and identify headings more easily, enhancing situational awareness for the pilot.

This dual increment system strikes a balance between granularity and usability on the instrument panel, ensuring pilots can quickly interpret their heading relative to a course or waypoint while still allowing for sufficient precision in navigation.
