The dual crew solo on the F3 was a LL wazex round Wales, where the AD backseater draws a route, insists on navigating, takes you straight over a red dot within 2 minutes of entering low level, say "ah,**** it, you've got a map haven't you?" and sticks to playing with the radar & similar toys whilst Driver, Airframes navigates for the rest of his AD career.
To be fair, the early radar and looking out took all his attention, and I think every crew in the early days had the pilot doing the nav, especially at low level.
As for first solo hovering, opinions varied as to whether to do the checks 3 times, or once very slowly and carefully, because once you move the throttle you will have zero spare capacity for anything.
