As an ex-student of mine, Stoppers, I know that you'll be intimately familiar with all the rools 'n' regs...
Such as the VFR requirements stated in the UK Mil AIP ENR 1-2-1 which reduces the mandatory 'clear of cloud' vertical requirement in the UK LFS to 500 ft if above 140 KIAS (I'm assuming your steed can manage this..
) and below 2000 ft agl.
So, military Herc at 240KIAS in UK LFS. Height agl 250 ft, vis must be 5km or better, cloudbase must be above (250+500) = 750 ft.
Civil Vulcan at 141KIAS in transit. Must not be within 500 ft of people, vehicles, vessels or structures. Must not be below 1000 ft over congested areas. Vis must be 5 km or better, cloudbase (BKN or OVC) must be above (500+1000) = 1500 ft.
Civil Vulcan at 139KIAS in transit. Must not be within 500 ft of people, vehicles, vessels or structures. Must not be below 1000 ft over congested areas. Vis must be 1.5 km or better, aircraft must be 'clear of cloud and in sight of surface'.
So, just because the Wx looks OK to an experienced UK LFS operator, it doesn't mean that it is necessarily legal for a civil aircraft.
Oh, and I'm all for pressing-on-titties!
