Scottish FIS, for example have their own code.
4. SSR – Mode A 4A. Identification 4A.1 When using Mode A to identify aircraft, one of the following methods is to be employed: (1) Observing the pilot’s compliance with the instruction to select a discrete four digit code; (2) Recognising a validated four digit code previously assigned to an aircraft callsign. When code/callsign conversion procedures are in use and the code/callsign pairing can be confirmed, the callsign displayed in the data block may be used to establish and maintain identity; (3) Observing an IDENT feature when it has been requested. 4A.2
Caution must be exercised when employing this method because simultaneous requests for SPI transmissions within the same area may result in misidentification. Aircraft displaying the conspicuity code 7000 are not to be identified by this met
Fatcontoller....Yes you are. Previously, the only conspicuity that cannot be identifed using ident WAS 7000. Now its all of them. Since the update 2 months ago. Your local orders at wherever you used to work may have said you couldnt, but thats not MATS1. And it isnt 'blindingly obvious', its actually a perfectly sound method of ident for professionals to use that has now been removed.
