Safe Flying by Fileing a plan
Sould the pilot not know who his parent station is when operating in the U.K.
The same systems operates in France and they are very hot if the flight plan is not closed after landing.
Ther are a number of pilots flying in and out of airfields that have no aftn and some have no ATC and all these pilots should know the importence and the reason when and why to file a plan and how it operates and to activate when airbourne also the importence to close the plan on arrival.
If you don,t know ask and learn and ATC will look after the plan and the follow up action as and when.
There is a CAC publication out on flight planning and it was three pounds sterling the last time I checked so for three pounds it save a lot of aggro when pilots don,t follow the recommended rules.
It is nice and reassuring how safe your flight can be by following the guide lines.
