If you have an engine failure (assuming SEP) get a Mayday out double-quick. We (radar) can plot your position, give you surface wind, things we may know about the area (eg nearby runways!) and vector a rescue cab to you. Don't worry about phraseology - just "Mayday", C/S and engine-failure will get us going.
If it starts again by all means downgrade to a Pan or cancel altogether if you as the a/c commander feel it's the appropriate course of action. Whatever you do decide, rest assured we'll be keeping a blummin' close eye on you until you're landing of your own volition! Just in case!
