"15-10-10...moving together, stop together" How I remember that - and if a pilot forgot to say 'moving together" PDQ, the navigator would immediately call "Check cheeses!".
Simulator training was very comprehensive, but coping with a pairs night VRIAB and going through the rigmarole of reconfiguring below 300 KIAS, including changing hands for the aileron gear lever, setting the autostabs to low speed, then from clean to 15-10-10, gear down, 30-20-20 check cheeses and blow gauges, 45-25-25 check cheeses and blow gauges...all with their own limiting speeds and trying to keep spaced on the leader, well, that was pretty darned demanding for an ab initio student!
