I'm a Wycombe Pilot!

Make sure you read up very carefully on Wycombe's joining and circuit procedures, as they are decidedly non-standard. This is principally because there is no deadside (as that side is used by gliders & tugs).
If it's busy, you should expect to be sent into the overhead, descending to fly overhead the runway (ie, along it) at 1200' QFE, then to execute a descending to turn to 1000' to join the downwind leg.
If departing from 25, you need to climb out on a *track* of approx 240, for noise abatement. If departing on 07, you need to execute a turn to track 020 as you pass the upwind end of the runway (can be fun!), due EFATO/noise considerations.
Also bear in mind that Wycombe has "proper" ATC, so you need to ask permission, and be cleared, to do everything. Also, when it's busy, there will be a Ground Frequency in use on 121.775.
This is just a quick summary of the main points to be aware of....hope it helps.
