APR E6-B2HL Pilot Flight Computer

APR E6-B2HL Pilot Flight Computer

The Aero Products Research APR E6-B2HL Pilot Flight Computer is the Ultimate Wind Triangle & T/S/D computer that 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. Nautical and Statute scales for WAC and Sectional Charts are on two rulers on the sides of the slide.

The high speed slide shows a crosswind component grid and nautical/statute scales for WAC and Sectional Charts. Also included is a Compressibility F Factors Scale. This scale solves for pressure altitudes from 10,000 to 50,000 feet and True or Calibrated Airspeed from 200 to 550 knots.

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.

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

MEETS FAA AC 60-8 REQUIREMENTS. Custom case. Anodized aluminum.

Dimensions: 4 7/8" x 9 5/8"
