Funny how NATS usual policy of only possibly ever recruiting ab-initio through their precious in house college and the frankly disgusting comments bandied about on this forum by their own ATCO staff about being so 'superior' in regards to BB and KK are now really exposed like the trash they are
Yes, it may take a special type of ATCO to validate at certain units, be it BB, KK or in this instance, SS.
However. It does not have to be a NATS ab-initio trained, NATS unit previously validated etc etc ATCO.
