CAP413 1.5.2 and 1.13.3 and LASORS Safety Sense 22 p.13 give conflicting information regarding requests to an ATSU for Flight Information Service or Radar Information Service or MATZ Penetration or Zone Transit or whatever.
Yesterday I asked the CFI for his interpretation of the rules. He is an R/T Examiner and has the latest information from the authorities (who, hopefully, will clarify the situation in print at some stage).
The following is the correct format for these types of messages:
AIRCRAFT:
Station address
Callsign
Request
ATSU:
Callsign
Pass your message
AIRCRAFT:
Callsign
Type
Point of departure
Destination
Routing
Position
Altitude
Request
Notes 1: Heading is not required. VFR/IFR not required. Pressure setting not required.
Notes 2: If your initial request is for (say) a “MATZ penetration” then the ATSU require, in the subsequent request, the type of service through their MATZ or in their Airspace e.g. “Radar Information Service”.
