Rules of the Air, Rule 11 Flight within aerodrome traffic zones.
(6) The commander of an aircraft flying within the aerodrome traffic zone of an aerodrome must—
(c) if the aircraft is fitted with means of communication by radio with the ground, communicate the aircraft’s position and height to the air traffic control unit, the flight information centre or the air/ground communications service unit at the aerodrome (as the case may be) on entering the aerodrome traffic zone and immediately prior to leaving it.
I learnt to fly at Barton in the early 70s and spent the next 32 years there in various roles. So I have an emotional connection.
Getting back to flying in 2014 after a 10 year hiatus and now doing quite a bit, this rule has not been foremost in my mind. In fact on reflection, I can't recall over the past 5 years whether I've complied or not at many aerodromes with an ATZ.
Suffice to say I've not been pulled up about any failures nor received instructions to present myself for 're-education'. However, my comments elsewhere about the prevalence of paperwork being raised on account of failing to adhere to this rule in fact centre on this location.
I'm happy to now follow this rule to the letter, but feel that mentoring Forumites who might operate into and out of my spiritual aviation home and may have forgotten its importance is worth bringing up.
