Conversely, as a very young Nimrod Eng, I had ACM Sir Peter H (then CAS) in the left hand seat, with my Flt Cdr in the RHS. Throughout the seven hours that were mainly spent below 500ft, I was continually warning CAS of his height, speed and bank angle departures. As he left the flight deck when we delivered him to Brize, he thanked me "for looking after him". I learned about nagging pilots from that and never looked back!!
