RIS - clock code vs compass points
Today Brize were giving me a RIS and calling traffic by compass points (e.g. Traffic NE, southbound, same level) rather than clock code. I was under the impression that they would only do this if you were manoeuvring, and that cruising (as I was) on a steady heading they would give clock code.
Could this be because the wind was strong, and therefore my wind correction angle would make their estimates of clock code wrong? (They didn't know my actual heading - I forgot to say and they didn't ask.) Wind correction was around 30 deg cruising at 90 knots in an underpowered DR400...

...in a turn.....
"Traffic 12 o'clock, correction 11 o'clock, correction 10 o'clock, correction 9 o'clock......"
Doesn't quite work does it?

Have had both, personally much prefer clock code, find it more precise. Unless manoeuvring, of course.
PS: same goes for wind. Over the years I've had a few controllers call wind on final in the compass point format. Hate it....

I can respond to either but I sometimes have trouble with the "right ten o'clock" or "left two o'clock"

Clock code if steady track, cardinal point if manoeuvring is how I play the game. Wind doesn't actually get taken into account so take all indications based on track, not heading.

In the days of my youth there was, allegedly, a controller who called traffic in cricket field terminology. He once gave traffic as "In your mid on at 5 miles." The puzzled pilot responded, "Erm. Am I batting or bowling?"

I've been party to the following..
ATC "Traffic 10 O'clock, same direction, similar level...."
A/C a few minutes later "Er....we can see one in our 2 O'clock, is that him?"
ATC "Yes, sorry, I've got my digital watch on..."
ATC "Traffic 10 O'clock, same direction, similar level...."
A/C a few minutes later "Er....we can see one in our 2 O'clock, is that him?"
