In the mid-70s after some years of VOR tracking, I transferred to the B707 fleet which was just being retrofitted with early INS, (Litton7 ?) or Omega. These early INSs were prone to a not insignificant drift rate so, as Airclues alludes to, we were often not exactly sure where we were after a long oceanic sector. Today's crew NEVER are unsure of their exact position such is the improvement in nav equipment. This does breed a different mindset though..........................
For the "magenta line" generation a "map shift" seems to be totally ignored. Why not just accept that the ND never lies?
