The Chichester Index Card is born (CHIC). This 3x5 has flight almanac data and tarmac precalculation for a chosen destination. The 8" circular slide rule is preset before takeoff for quick inflight Doniol multiplication. Hp for any 4 minute interval only takes 4 minutes to precalculate while enroute.
