    Greg,

    You seem satisfied with these new tools - on the ground. 
    Looking forward to hear of your experience in the air.

    I assume Hp means projected height?  Btw, what more types of Hx do
    people use.

    H

    Attached is the second evolution of the Hp Doniol table for aircraft. This versionof  Hp reductions are done every 8 minutes for an hour with the between 4 minute intervals done by splitting the difference between the Hp values. This cuts the precalculations in half. The plot shows a 7' dispersion for 16 observations made by a navy MK V bubble octant. Conditions were ideal. The averager was not used. For flight observations the dispersion will more than double due to aircraft movement influencing the octant bubble.
