The weather is a red herring... The CPLS is a red herring.... The planned route is a red herring.....The a/c serviceability now that is of concern.
To put this to bed, CPLS was fitted to the a/c when it arrived in Aldergrove,fact. did it take off with it fitted? I have no idea, I didnt witness the departure.
Was the a/c serviceable? who knows, but if you saw it 24 hours before would you go flying? I would, The gingers would say it was safe! Good eough for me..... but is that sound?
