Do you use the Semicircular rule?
Hello,
Im new to the PPL flying after flying in the RAF. On a cross country yesterday i was using the semicircular rule due to amount of haze. I was tempted to take RIS rather than just FIS because of the amount of traffic that was flying in opposite directions at similar levels. This is not a telling off to those people i am just interested how many of you use this rule when flying VFR?

Don't get too uptight. At least you are paying attention and using your initiative when faced with poor visibility, so well done.
No, you will not find everyone following the same advice.
But, bear in mind, the VFR quad/semi is only advice and you can fly anything you want, even above 3000' in VFR (airspace permitting).
A RIS is a good idea.

Most PPLs seem to fly below 3000 feet possibly because they don't want to complicate things by
a) flying quadrantals and
b) having to set 1013
Practically speaking with the average UK weather and controlled airspace it is not very often possible to adhere to the quadrantal rule.

I usually try to fly at odd heights (not a problem, really, given my apparent inability to hold altitude for more than a few seconds at a time
) to avoid the likelihood of finding someone else at my level. That and a constant lookout, including moving the nose around once in a while to have a look under it, pretty much do the trick.
It might help that straight and level bores the hell out of me so I'm usually up to something, even on a cross country, even if it's just butter-churning the stick a bit. It breaks the monotony of a boring flight and helps me keep a good lookout because my scan territory is always changing.

You can still fly the QNH above 3000 and report alltitude.

This implies you only fly on QFE. Or am I being pedantic??

As a general rule, if I'm on a local flight (eg. a triangular route and turning at Point A and Point B, returning to the same airfield) I'll fly at an odd altitude, say 2700ft, rather than the oft-used 2000ft or 2500ft.
If I'm travelling cross-country and cloud base permits, I'll usually aim for a quadrantal flight level, providing my course isn't taking me just either side of 180 etc etc (which would mean a level change at every waypoint!). If the course is a dead straight line then this isn't a problem.
All of my flying is VFR.

"and cloud base permits"
This is an essential consideration on our often cloudy little island.
Sometimes the man upstairs has put the clouds at awkward levels that do not fit with our direction of flight - what to do in this inconvenient situation?
By the way, to complicate things further it is all different over in Italy.
Basically - fly by the quadrantal rule when safe to do so.

I might be wrong here and may have it reversed but don't you use the semi-circle rule in controlled airspace and the quadrantal rule in uncontrolled airspace
