The main thing is to stay to the West of the airway Q41. To do that you'll need to track to a point about 5 NM West of ORTAC. If you are happy to fly at 3000 ft you can forget that and just go direct as you'll be below the airway.
Bournemouth Radar will give you a service and you should expect to change to Jersey zone about 35 nautical miles from Alderney which should get you a clearance into the Jersey zone unless you are going very fast. They will quickly pass you to Guernsey approach who will give you the traffic, runway in use, current weather and joining instructions. They will hand you over to Alderney tower when you are joining base leg.
Watch for turbulence on short final to 26 or over the cliffs on Approach to 08 especially in gusty conditions.
The grass runways aren't available at present so check that the wind is OK for your cross wind capability.
It's a lovely little island so have fun!
