BonesThanks, that is basically what I did, except I called not below instead of not above, but that would have been for the transition, just was not sure about the semi circular rule.
The pilot just stayed on frq for FIS. As it was just me and 'im just a case of monitoring for any other traffic.

VFR aircraft are not subject to any mandatory levels. The Quadrantal and Semicircular rules are for IFR aircraft only but many VFR aircraft comply with them too. The point is that you can't force a VFR aircraft to fly at any level except when inside a CTR and even then you cannot allocate a specific level.If you give a VFR aircraft a radar heading to fly or a level to maintain andhe then flies into cloud, loses control and crashes it is yourresponsibility and you would be charged with manslaughter. VFR aircraft haveto remain clear of cloud at all times and so a clearance must provide themwith the ability to do so. For this reason an aircraft cleared into the zonewill be given a height band to operate in rather than a level - "JHB777enter the zone, not above 3000ft on QNH 1021" - the important bit here being the NOT ABOVE bit as he can freely alter height between 3000ft and sea levelif needed to remain VFR. If there are other aircraft nearby at say 2000ft and there would be aconfliction if the aircraft had to leave 3000ft then you simply pass traffic information. There is no requirement to separate VFR aircraft inside a CTR. Of course, once a pilot has left your zone and is in the FIR he can do whathe wants - your only task then is to warn him of potential conflictions. bones bones@xxxxxxx http://woodair.net -----Original Message----- From: jhb_airlines-bounce@xxxxxxxxxxxxx [mailto:jhb_airlines-bounce@xxxxxxxxxxxxx] On Behalf Of F FISHER Sent: 17 July 2008 09:50 To: jhb_airlines@xxxxxxxxxxxxx Subject: [jhb_airlines] SemiCircular Bones My first contact last night,was a C172 at 3500ft VFR EGBE-EGNV, asking for overhead transition Leeds. Which I granted, also pointed out that current route would be MATZ penatration Netherthorpe/Leeming. The pilot checked charts and agreed. He stayed on frequency for FIS to Durham. I was the only controller in the area. Thinking about afterwards, I dug out and checked the semicircular rule chart, and see that for west to east, I should have dropped him down to2500, or taken him up to 4500, is that correct?? or which would be correct.Had not thought about this previously.
