    Re: Looking for references on "aiming off"

    Air Force Manual 51-40, 1973 page 16-7 says to aim off 10% of the distance flown since the last fix but not less than 60 NM.

    I'm a PhD student and am working on a paper quantifying when and by how much to aim off. Can anyone point me to any references on the subject? For instance from [NavList 10886]:
    "Noonan could be expected to have known this technique since he knew Weems and Chichester had popularized in 1931."

    How did they do that?

    Has anyone heard of off-aiming in maritime navigation, perhaps under a different name?

    Thank you very much.

    At the moment, my results are still preliminary but I would be happy to share them with anyone who is interested.
