777 Polar Operations
Hello,
I operate the 777F, though our current Ops Spec does not include Polar operations. I would appreciate clarification on your airline’s procedure for transitioning from magnetic to true heading using the HDG REF switch when entering Polar regions.
From my research, the 777’s primary and preferred roll mode for Polar operations is LNAV, which can be used with the heading reference switch in the NORM position. However, when using HDG SEL or HDG HOLD, a manual selection of TRUE for the heading reference is required.
I’d appreciate any insights you can share regarding your airline’s s procedures.
Thank you!
