4.63.2 Describe the method of passing traffic information using the clock code.
The specific direction from one aircraft to another is usually expressed using the 12 hour clock method.
- For example, if you see an aircraft over your right 'wingtip', it is said to be in the 3 o’clock position from the nose of your aircraft.
- Each 5 minutes of the hour represents a 30° arc. Therefore, if you are told that an unidentified aircraft is at your 10 o’clock position, it is (2 x 30) = 60° to the left of the nose of your aircraft, slightly ahead of the left wing.
