no-compass approach no-compass approachA radar approach or vector provided to a pilot when the compass or directional indicator is malfunctioning. Instead of telling the pilot which headings to fly, the controller observes the radar track and issues the control instructions, “Turn right,” “Turn left,” or “Stop turn,” as appropriate. In an emergency, a direction finder can be used to create a no-compass homing service. |
