AFE AS-3 16” (41cm)

AFE’s popular 41cm / 16”scale rule design but with the outer edges marked with nautical miles in 1:500,000 & 1:1,000,000 scales. The centre line is marked with statute miles and kilometres in 1:500,000 scale. An essential piece of flight planning equipment for those countries where “half-mil” and “one-mil” charts are standard.
