Why on earth is this guy filing a flight plan? - none of the LARS units and the London FIR person will not get a copy (unlesss he addresses it directly and then they will probably ignore it).
Book out from Biggin IFR.
And get charged route charges
.
It's not just on the basis of the submission of the flight plan. Aerodromes are also required to submit copies of logs with whether aircraft departed IFR or VFR. On the basis of these route charges are incurred.
How does the pilot find his way legally from Plymouth to Prestwick? The Volmet is available on the ground in Prestwick so no doubt it is available mush further away as 5000ft plus!
Sorry, you're going to have to explain this one to me as I (and I expect many others) haven't got a clue what you're talking about!
