APR E6-B9WHL Pilot Flight Computer

Product Description

The Aero Products Research APR E6-B9 Universal Wind Triangle & T/S/D Navigation Computer has been upgraded to E6-B9WHL with the new, exclusive Windspeed Cursor Arm for low and high speeds. This Cursor Arm quickly shows groundspeed, wind correction angle, and heading. This revolutionary design eliminates two set-ups and the need to mark a dot on the plastic disc.

The new APR Windspeed Cursor Arm makes solving wind problems a breeze. Simply set your true course, rotate cursor arm to wind direction, and read the wind correction angle and groundspeed. Instructions for Windspeed Cursor set-up are printed at the top of the low speed wind slide.

The E6-B9WHL Time/Speed/Distance computer solves all major navigation computations and calculates necessary flight planning and en route navigation requirements.

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 slide-rule mathematics are quickly determined. The unit has write-in TC to CH boxes.

The low speed wind slide shows speeds of 40 to 270 knots or miles. Instructions and user-friendly scales printed on the T/S/D computer make learning faster and easier and allow for more accurate reading. The low speed (40 to 270 knots or miles) slide has instructions to solve for wind correction angle, ground speed, and headings while the high speed (100 to 820 knots or miles) side of the slide shows a compressibility F factors scale, headwind and crosswind component grid that depicts relative wind angle, and nautical and Statute rulers for Sectional and WAC charts are printed on the sides of the slide.

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