I believe the same is true for Denham, arriving / departing to the North. That portion of the ATZ for these airfields (also White Waltham) that is under the Heathrow zone is NOT class A airspace. In the case of Fairoaks, the ATZ extends from sfc to 1400' QNH - above that, you need an SVFR!
Not strictly true.(I think you mean the London TMA, it is impossible to be beneath a CTR......)
The part of the Fairoaks ATZ within the London CTR is Class A. It is subject to 'notification' in ENR 1-4-2 2.1.1.1 para (vii)(a)
"IFR procedures apply in all weather conditions in the London CTR except for flights made in accordance with certain special procedures detailed below:
(a) The access lanes/local flying areas for Denham, White Waltham and Fairoaks, are hereby notified for the purposes of Schedule 8, Private Pilots Licence (Aeroplanes), sub-para 2 (c) (ii) and Basic Commercial Pilots Licence (Aeroplanes) sub-para 3 (g) (ii), of the Air Navigation Order 2005 when there is a flight visibility of at least 3 km;"
VFR do not apply in Class A. IFR do not apply in Fairoaks, Denham or White Waltham ATZ Class A portions, no IFR procedures exist.
See AD 2-EGTF-1-3
That part of the Fairoaks ATZ outside the London CTR ( and beneath the London TMA) is Class G. VFR apply. So can IFR Rule 29 Minimum height Rule.
So you will see that compliance with minima equivalent to SVFR 3km minima is necessary to access Fairoaks and Denham. You will note that the 'notification' permits a concession for PPL and BCPL holders who do not hold an IMC rating who would otherwise require 10km. White Waltham itself lies just on the edge of Class G airspace therefore is accessible under VFR therefore requiring VMC subject to Schedule 8. The airspace within the subject ATZs 1500 feet QNH and above is ceded to Heathrow.
Clear??
