A330 True North/CFS
 

Hello,

With regard to 330 North Atlantic operations when would a witch from Magnetic to True North be initiated and exited ? To confirm is it the first waypoint prior to NAT entry and the first point post NAT exit ? Also how would this work with regard to random filed routes across the Atlantic. Would flights similarly routing over Russia use True North?

Also could CFS fuel be explained (What it means) and when it’s used ?

many thanks
