(b) All interested ATSUs en-route;

 
(c) The London FIR - EGZYVFRT;

 
(d) The Scottish/Oceanic FIRs - EGZYVFRP (when necessary);

 
(e) All foreign FIRs that the aircraft will fly through or land/depart from. 

 
Pilots must ensure that well-defined, significant points are included in the FPL to indicate where the aircraft will cross the UK or near continent coastlines. This information should be shown in Item 15 (Route) or Item 18 (Other information: EET/).   Additionally, for flights to/from France, the French Authorities require the frontier crossing point (the UK/France FIR boundary position) to be included in Item 15 (Route) of the FPL. To assist pilots, the UK now includes the ATS route reporting points on the Southern England and Wales 1:500 000 chart. These can be used as a frontier crossing point. A position may also be shown as LAT/LONG, or as a bearing and distance from a route reporting point or navigation aid.
 
Example:
 
Cap Gris Nez - RINTI
Cap Gris Nez - 51N00130E
Cap Gris Nez - RINTI23005
Cap Gris Nez - DVR16010
 
The EET for this position should be shown in Item 18 of the FPL (Other information) in the format EET/LFFF(elapsed time) or EET/EGTT (elapsed time), depending on flight direction.
 
Example: EET/LFFF0145 (UK/France) or EET/EGTT0020 (France/UK).
 
Recommended VFR routes from the Solent CTA to the Channel Islands are shown in the UK AIP Aerodrome Section - Jersey, page AD 2-EGJJ-3-1.  
 
Pilots may elect to file their return FPLs at the same time as they file their outbound FPL. The normal requirement is to address the FPL solely to the aerodrome of departure. However, if the pilot also adds the addressee of the destination aerodrome, then this will ensure that the return destination in the UK is aware of the intended return flight, just in case the return FPL is not transmitted from the non-UK country. If the return flight occurs on a different day, pilots must ensure that the date of flight (DOF) is shown in Item 18 of the FPL.
 
Example: DOF/070922 (DOF/year/month/day = Date of flight 22 September 2007).
 
 
Special VFR
A Special VFR Flight (SVFR) is a flight made at any time in a control zone which is Class A airspace, or in any other control zone in IMC or at night, in respect of which the appropriate air traffic control unit has given permission for the flight to be made in accordance with special instructions given by that unit instead of in accordance with the Instrument Flight Rules and in the course of which flight the aircraft complies with any instructions given by that unit and remains clear of cloud and in sight of the surface.
