Re: Treatment of IFR flight plans (UK, outside Class A)
How does the VFR departure airfield know that it is supposed to re-address the FP to the destination?
If one faxes an FP to the departure a/f then it's obvious, because the fax obviously didn't come via the AFTN. So, faxing an FP to Heathrow works OK. Except that they (like every other similar service to date) don't guarantee to handle FPs for flights wholly outside the UK, whereas Austrocontrol does.
