Have the telephone number of the Rescue Co-ordination Centre (Kinloss) in your mobile phone.....and call them. They can triangulate your position and give you the nearest suitable airfield.
I kid you not, many years ago I worked at a Radar Unit and a German F4 had a total electrics & hydraulics failure. Using a mobile phone he was vectored to a military airfield equipped with a cable, where he made a safe landing having 'blown' the gear down and using the arrestor cable to stop.
