SESK: Stuff Everyone Should Know · sesk.info/pilot-vor-to-from-course
You want to fly to a VOR, but a centered CDI shows FROM. What should you do?
Rotate the course selector 180 degrees.
- Keep the same course setting
- Rotate it 180 degrees ✔
- Turn the receiver off
Why: A centered CDI can represent either direction along the same line. Rotating the selector 180 degrees changes the reciprocal FROM course to the desired TO course.
Huh, didn't know that: After selecting the TO course, fly a heading and apply wind correction to keep the CDI centered.
The VOR said FROM, so the pilot gave the knob a complete change of perspective.
