View Full Version : VRPs over Built up Areas

Why are there VRPs over the precise centre of large built up areas that cannot possibly be safely alighted clear of by the average light aircraft, due to the controlled airspace above?
E.g. Guildford,Chelmsford, Tunbridge Wells, Haywards Heath....

Because you are supposed to report passing or relative to them, not necessarily overfly them.

Incidentally they are officially "Visual Reference Points", not "Visual Reporting Points" as often assumed.

The VRP guides specifically say not to fly directly over them.

yes; but how many times have your heard ATC say "report at Bishops Waltham" or "cleared into the zone via Bishops Waltham" etc etc.

Is the answer to reply " negative; but will enter the zone 1nm N of Bishops Waltham"?

Turniphead

Surely that would be the town/village being referred to, not the dead centre of the VRP.

You are not visual with a VRP when its underneath you, unless you are inverted :}

ATC is being naughty, turniphead.

MATS Pt 1 Sec 3 Ch 4 3.5
When issuing routeing instructions to VFR flights, controllers should endeavour to avoid known areas of high traffic density, and should also avoid concentrating traffic over VRPs. In order to achieve this, instructing pilots to route over or hold at VRPs should be avoided whenever possible.

Yes of course ATC is being naughty and I appreciate your quoting their manual. hardly practical to quote that at them over the R/T.
So...I repeat ..do we say 'negative' , or do we comply and file complaint when on the ground.

The Bishps Waltham ('x in a circle) on the half mil is precisely overhead the town. Those of us who fly accurately to where we are told will find it right under our nose and quite clearly visible. There is never anything in any clearance to report when within sight of somewhere. Could mean any distance depending on viz.

Just use an element of common sense Turnip head. We are looking for you to be in the vicinity of rather than at a VRP when flying VFR.
For example we have a VRP notified as Cardiff Docks, rather a large expanse and it would be hard to be precisely over the top of it when it covers several acres.
So when in the vicinity of a VRP, report the VRP.

( of course vicinity of is an inexact science)

Upon leaving the zone at Liverpool (via the Seaforth or Kirkby VRP) we are asked to report 5 for rejoin, which we do. Then we are told to route to the specific VRP, i.e. report Kirkby, not to the side or anything, but directly over it - and this is how I have been taught, so it seems there are more angles to this!

Mazzy,

Kirkby and Seaforth are both inside controlled airspace. (Ok then, they are right on the edge of controlled airspace, such that I wouldn't want to overfly either of them without a clearance). Therefore, although concerns about being able to alight clear still apply, it's probably reasonable to assume that concerns about routing traffic overhead a "known areas of high traffic density" don't apply here, since ATC will know about traffic over the VRP and control it appropriately.

Outside of controlled airspace is a completely different question.....

Thanks mate :ok:

Traffic is always routed one way, i.e. in at Kirkby out at Seaforth, and if you specifically request a non standard rejoin (standard procedures to Liverpool) then it will obviously only be granted if there is no conflicting traffic, who is implementing the standard :)

And having flown them a few times i think not about 1.5 over the city is decidely iffy for alighting clear(except maybe taking the Mersey) and marginal legally and as such I'm always gunning for not above 2 if poss.

I asked one of the controllers there once why it was such a low limit, and he said it was a historical thing dating back to when the airspace above was Class A and it was to therefore avoid having all the GA SVFR...if that airspace IS now class D is there any possibility of the standard zone clearances being not above 2??
