Reading through some NOTAMs and came across this.
With effect from 1 January 14 operators shall comply with article 5, paragraphs 2 and 3, of the commission implementing regulation (EU) number 1079/2012 dated 16 November 12 in that an operator shall not operate an aircraft flying under IFR or VFR in class A or c airspace within the united kingdom unless the aircraft radio EQPT has 8.33 KHZ channel spacing capability. 2014-01-0003/AS6
Does the fact that you'd be SVFR negate this requirement? Otherwise I'd have thought there'd be plenty of non compliant machines landing at Ascot next year!
