So, for 25 from the south, that would be overhead 07 numbers at 2000', "assertive" descent and turn towards Yateley, down disused 14 to be level at 1000' for entry on the downwind leg?
For 07, overhead 25 numbers at 2000', up disused 32 descending to join the downwind leg at 1000'
For 25 from the south - over the 25 numbers at 2000ft, descend deadside to circuit height using the disused Runway 32 to keep clear of Yateley. Cross the 07 numbers at circuit height, SEP 800ft, then integrate downwind.
For 07 from the south - over the 07 numbers at 2000ft, descend deadside to circuit height using the disused Runway 14 to keep clear of Yateley. Cross the 25 numbers at circuit height SEP 800ft, then integrate downwind.
From IAIP AD 2-EGLK-1-5:
All circuits are to be flown south of the aerodrome.
Circuit heights: Light single-engined aircraft - 800 ft (AD QFE); Twin-engined and executive aircraft - 1200 ft (AD QFE). At night the circuit height for all aircraft is 1000 ft (AD QFE).
It's not difficult provided that once you have crossed the runway numbers you don't dilly-dally with the dead-side descent. For an SEP you've got 1200ft to lose in the turn. Just keep an ear out and a sharp look out on the dead-side. Always look out up the downwind leg for direct downwind joiners ('cos people do...), stay north of the M3, and always look out up the final approach track for 'optimistic' straight-in (or excessively wide circuit) traffic ('cos people do...).
