Yoth....
Is it not so that WM..at approximate ratio 70%W/30%M was stored in Jersey for Channex with the Electra?
Some British Dart airlines had strange ideas on WM. JEA never followed Fokker Manual on either trimming procedures or use of WM. WM selection consideration for Go Around was ignored. WM tanks held 30USG per side? Usual quantity carried in tanks in all circumstances was about 5USG? Bad news to run out of WM halfway through a wet operation!
