Minimas
Thanks Jim59
Its all our night mares i'm afraid.
Your reference dated 26 September 2012 appears to have been revoked. See UK AIP ENR 1-2-1 31 Mar 2016, ENR 1.2 Visual Flight Rules. The exemption is removed from the text, 1500 metres is the VFR absolute minimum.
In the good old days we used to receive AICs on changes, apparently there's no longer the financial means. So, we should all go to bed at night reading the ANO and the AIP from cover to cover before closing our eyes, alternatively we could simply loose the will to live.
