Course Deviation Indicator (CDI) and Distance Off Track

The triangle symbol (“) referenced to a bar graph shows your position relative to being on-course. When the bar graph is to the right of the triangle, you must fly right to return on-course. In the example below, the bar graph indicates you are off-course to the right. Fly the aircraft in the direction of the bar graph (left) to return on-course.

A single dot thickness bar indicates that CDI sensitivity is set to 0.3 nm full scale per side. The two dot bar indicates a sensitivity of 1.0 nm full scale per side. The three dot bar indicates a sensitivity of 5.0 nm full scale per side. The manual sensitivity of the CDI may be set to 0.3, 1.0, or 5.0 nm full scale per side.

The number shown on the edge of the display opposite from the triangle symbol shows the distance off track. The numbered values of Cross Track Error are in the direction you are off course. If the numbers are on the left side, fly right to return on course. The displayed value ranges are: 0.000 to 0.999 nm with 0.001 nm resolution, 1.0 to 9.99 nm with 0.01 nm resolution, and 10.0 to 99.9 nm with 0.1 nm resolution.
