If we're starting a vote I think BC is wrong too.
But I though most NATS aerodrome units verified and validated the SSR on the ATM before transfer to the centre. If that is the case, why does the centre need to repeat the exercise?
For the benfit of those in other countries where I'm not sure the same procedures apply, in certain circumstances in the UK we can deem SSR data to be validated and verified if the aircraft is coming from another unit that is capable of doing this.
