Freight Dog 2000:
"not following the emergency turn"
I don't think you realise that in those days the FAA did not allow an emergency turn in the first 1500 feet of the Net Flight Path (I don't know if that has changed).
The CAA allowed such a procedure provided that the bank angle did not exceed 15 degrees.
So, as a DC-10 captain with Fred I could lose an engine on take off from 26 at Gatwick, turn gently 10 degrees to the left or so, avoid Russ Hill and clean up on the new heading. This enabled all the UK operators coming out of Gatwick to take off at a much higher weight.
And so it was that I discovered when later flying an ex-Laker DC-10, now on the N-register, that my take off weight from 26 at Gatwick was much reduced because the emergency turn was not allowed and I had (in theory at least) to grit my teeth and head for Russ Hill.
Whether I would have done just that you shall never know.
