Dubtrub, you perhaps have in mind rule 39(3)
(3) The commander of an aircraft flying within the aerodrome traffic zone of an aerodrome to which this paragraph applies shall:
(a) cause a continuous watch to be maintained on the appropriate radio frequency notified for communications at the aerodrome or, if this is not possible, cause a watch to be kept for such instructions as may be issued by visual means;
(b) where the aircraft is fitted with means of communication by radio with the ground, communicate his position and height to the air traffic control unit, the aerodrome flight information unit or the air/ground radio station at the aerodrome (as the case may be), on entering the zone and immediately prior to leaving it.
------
The rule applies to Gov aerodromes, aerodromes with ATC and FIS during hours of watch and licensed a/g fields during hours of watch.
Trouble is, if someone is flying a circuit via the outer planets, they will be unlikely to consider that this rule applies to them, assuming (doubtfully) that they have ever heard of it.
