Oh, and mad jock referring in a derogatory manner to "some gimp in OPS" does display a rather poor attitude to those who are probably your colleagues or customers. Hardly likely to endear you or make for a good working environment wherever you may work. In my experience there are individuals who might fit that title in all walks of life, and that includes on flight decks, sitting in front of radar screens and many others.
Indeed if you read my previous posts you may realise that far from being the omission of 'some gimp in Ops' (RPLs??), it may even be 'company policy' to not admit to being PRNAV.
