Contemporary commercial planning documents show a planning block time EGPK/CYQX of 4.30 hrs.
I have a fuel plan for a B707-321 [non-fan, same engines as the DC8-30 I think ?] for the sector EGKK/BGSF, planned as 4.25 block, as follows:
EGKK/BGSF 1804 Nmiles, wind average component -003, FL 350, time 4.01, fuel 61830 lbs.
Contingency fuel 3090 lbs
Alternate CYFB 500 Nmiles, wind average component -020, time 1.21, fuel 17390 lbs.
Contingency 830 lbs.
Holding 40 mins fuel 7950 lbs
Approach 850 lbs.
Total fuel required 91,940 lbs.
These figures are all based on actual performance 4% worse than book - by this time, the aircraft/engines were showing their age !
Hope this might be of interest/use
PS
Should have added that this was based on M.82 cruise.
