INTEGRATED FLIGHT DATA AIR NAVIGATION COMPUTER SYSTEM

摘要

An air navigation computer having a calculator side consisting of a lower disc inscribed with log-distance, compressibility, Mach number and temperature error scales; a central disc inscribed with "TRUE AIR SPEED/GROUND SPEED" and having log-time, density altitude and temperature scales, and a Mach number and temperature error window; and an upper disc having a density altitude window, a pressure altitude scale and an equivalent-calibrated air speed cursor assembly. A computer-wind side includes a relative bearing-cursor assembly disc that is laminated to the reverse side of the calculator side-lower disc and is inscribed with "TRUE AIR SPEED/GROUND SPEED" and radially-aligned wind drift and course indices at the 180 DEG relative bearing value with a radial cursor line extending between the wind drift and true air speed/ground speed indices. A trig-log scale-inscribed disc is interposed between the relative bearing-cursor assembly disc and the calculator-lower disc, and a compass indicator disc is mounted on the relative bearing-cursor assembly disc.
