"Some airports have their own specific comms failure procedures in the AIP aerodromes section, so it's worth being familiar with your home base."
I've heard of this procedure at Bournemouth, there was one at Cardiff also which involved flying around the Wenvoe TV mast twice in a specific direction! Remembering the damn thing was too difficult for me...But I remembering searching high and low for where all this was written down but it just seemed to be word of mouth. There's nothing in the AIP that I can find. Whenever I used to take students over the tower at Cardiff, the controllers told them about it now and again, so it must be published somewhere surely???
