Outside of controlled airspace it does not really matter. From what you have said it is mainly for SAR purposes, and the thing to ask youself is if it was not over the sea or bad terrain would you even bother ?. .Even on a VFR plan in the UK outside CAS you can change your mind and go IFR - but you must then comply with IFR as regards terrain clearance and levels to fly.. .If you then need to cross or make an IFR approach into class D just make the decison early and let the approach unit know in plenty of time to formulate a plan !!. .If you are leaving from an uncontrolled airfield remember to activate the plan either by someone on the ground (AFISO or radio operator) or by calling London Information - have the dep. time route and estimates handy. . .Fax it to the parent ATSU.
