APR E6-B4 Pocket High and Low Speed Flight Computer Overview:

The Pocket Size Wind Triangle & T/S/D flight computer calculates all necessary flight planning and en route navigation requirements. Included on the unit are both low (40 to 270 kts or mi) and high (200 to 700 kts or mi) speed slides, a compressibility F factors scale, a Cross Wind Component Grid, and two rulers.

Scales are user-friendly and allow for quick, accurate reading. Instructions printed on the computer make learning faster and easier.

The Time/Speed/Distance computer determines fuel consumption solutions, density altitude factors, conversions for true airspeed & altitude, mach number, kilometers, minutes to seconds, statute to nautical to statute miles, off-course and drift corrections and provides slide-rule mathematics.

Also included is a complete comprehensive instruction manual with the bonus section Dead Reckoning Wind Effects Theory, Calculations, and Vector Diagrams.
