QBALL is a menu-driven application for the determination of exterior ballistics data for smallarms. QBALL calculates and displays remaining velocity and energy, trajectory data, wind deflection for standard or user-defined crosswinds, times of flight; all may be saved to disk, and output as hardcopy. Graphic displays of up to 15 trajectories are permitted on CGA/EGA monitors; each may be individually saved and recalled. Purely tabular data may be computed using non-graphics equipment. QBALL also calculates ballistic coefficients, point-blank ranges, effects of slant (up or downhill) fire, sectional density, gun free recoil, and muzzle velocity from field data (2 methods).
A bullet-lookup facility, usable on CGA/EGA equipment, may be used to retrieve the maker, ballistic coefficient, and weight of any of more than 500 listed bullets. The QBALL display is user-configurable. On-line help is available with CGA/EGA. Full on-disk documentation, with a document consolidation utility is included.
Registered users get an unlimited single-user license, printed manual, one FREE upgrade, bullet data file maintenance utility.
