If only I knew.....
When instructing a few years back I was following an aircraft from one of these organisations in the circuit one morning. Sitting alongside me was a Widebody Skipper who was getting a bit of currency in a lighty.
As our downwind following the preceding aircraft reached some ridiculous distance, he turned to me and commented "I fly smaller bloody circuits in a 767"!
But then this same training organisation also forbid intersection takeoff's because "that's not what airlines do." Clearly the person who wrote the SOP's has never been to any major airport in the world!
