The pattern should be kept as small as possible so everyone can see you. I flew to Stapleford once. They had some guys flying Cessna 152s downwind and base legs so far out i swear they left the ATZ!*
Big circuits.. Some need a map to fly circuits. Not at Stapleford this time, but an ex-colleague of mine was once phoned up by an irate instructor about him having transitted too close to him at the end of his downwind leg, with a student in control. The instructor got very short shrift because my colleague was actually carrying out a letdown via the NDB, in the overhead of the adjacent airfield and were quite correctly talking to them about their circuit traffic as they overflew their runway intersection. The complaining instructor was so far downwind he was in the ATZ of the adjacent airfield.
