SIFEBA

Sifeba produces pilot navigation aids designed to simplify visual flight navigation, particularly heading corrections when a pilot is off course or must divert. Its products are intended for use with aeronautical charts and help pilots determine course adjustments and estimate distances along a route. The NAV-AID RULE is a flexible plotting instrument made from synthetic material.

It uses a chart-specific nautical-mile scale, radials and arcs to help calculate heading changes, track error, distance flown and distance remaining, offering an alternative to the traditional 1-in-60 method. Sifeba offers versions for WAC charts at 1:1,000,000 and SEC/VNC charts at 1:500,000. The NAV-AID PLUS is designed for SEC/VNC charts and combines the plotting rule with a circular computer for pre-flight and en-route ground-speed, time and distance calculations.

Sifeba’s products are positioned as practical companions to aeronautical charts, supporting visual navigation even when GPS is available.
