Star Altitude Curves were meant to be used in high speed aircraft. Older exts on aircraft navigation give descriptions. (Particularly those by Weems.) Attached are works in progress. An excel spread sheet to compute and plot a set of curves. (Excel's forte is not plotting!) And a gnuplot input file. (gnuplot is an open source plotting program for linux and windows.) Turns out to be far from straight forward to label the curves neatly. Suggestions?File:File:
