Since JAR FCL 2 has been replaced recently by EASA, the new rules from Part FCL.060 b should apply.
This basically reconciles the rules for fixed wing and helicopters:
- 3 takeoffs, approaches and landings within 90 days on same type
- for Night VFR, only one takeoff, approach and landing on same type is needed (waived if you have an instrument rating)
Note that you cannot undercut a total of 3 landings for Night VFR, since you need them to be a pax-carrying PIC under any lighting conditions. But 2 of them can be in Day VFR.
So basically the F/W rules are now valid for helos as well and the "circuit" definition from JAR FCL has been dropped (it didn't make sense anyway).
