Relative bearing methods
Am I correct that pilots universally use the clock face relative bearing system – ie traffic at 9 O’clock ?
On boats I have always used a different system (which I have an idea is a navy convention). So that 9 O’clock would be called as red 90. 3 O’clock is green 90 etc. I have to say I much prefer it, partly of course because I am familiar with it, but it also seems faster and more intuitive; as soon as you hear red or green, you know which side, then swivel your head according to the number of degrees. Am I alone in this? Do any others use this? Perhaps navy fliers ? I guess it would not likely be easily understood by a random ATC or colleague ? |

The only time you use the clock code is to point out an aircraft position to another person in the aircraft. If you add colours to it, there is the possibility of confusing that with the navigation lights on another aircraft which if its coming towards you will be opposite to your own.

Also, flying with a (non ‘marine’) passenger, asking them to look for traffic... better sticking to something that everyone understands. |
I suspect that if you asked the average PPL which colour was on which wingtip, you would get a significant number of wrong answers! Always the clock system in aviation in my experience. I wonder what the Fleet Air Arm used? |

A Captain I once flew with, asked how he knew where to go, flying at night ? Well, Madam, he replied, can you see that red light on the end of the wing, out there ? ( the reflection was visible in a bit of plastic fitted for that purpose ) Yes. And can you see that green light over there ? Yes, well, I just have to fly between them !
|
best practice using the clock code is to prefix either left or right eg Traffic right 2 o'clock I wonder what the Fleet Air Arm used? |
Thanks! I will stick to the clock method.
A couple of minor points

Anyway. Not trying to be a smartarse, obviously there is no point in using an obscure personal system! I will stick with the clock! |
As pilot and sailor - I use green, red on the water and clock face in the air - and prey I don't hear myself using both on the same trip!

I broke an ankle last year and was provided with the modern type of elbow crutches. The handles were subtly shaped for left and right hands, but at first glance that was difficult to see, and I was forever picking up the wrong one first, so ..... I marked the handles red and green.

Apocryphal story has it that a fighter pilot wrote left/right on the appropriate glove to avoid confusion in a fight. |
A red and a green sock does it or me. So long as I remebered to put them on the correct feet!

Whilst Hearing Aids are oppositely coloured.
Green goes in one's left ear, red to the right. [I always think my way out of that confusement by considering the view as seen by the eye Dr.,- then it works !] mike hallam. |
Another vote for red/ green socks for sailing. They come under the list of essential items!
|
Most light aircraft passengers will not understand the clock code. My practice is to brief them: "point to anything you see and call 'traffic'. If it's close, call 'traffic close'". You can assess bearing by observing the direction they're pointing in. I tell them that "close" means you can see detail.

For juniors I've seen this reduced to "GO FOR IT!" (starboard tack, has right of way) and "NO WAY!" (port tack). |
