APR's CR Computer has been a favorite of professional pilots, navigators, and flight engineers for roughly Twenty Years. If you began your flying career with the basic E6-B type computer you will find both resemblances and essential differences in between the E6-B and the CR Computers. When you become acquainted with the CR computer it will more than likely be your favorite cockpit aid. Numerous of the scales on the calculator side are similar to those found on the E6-B. However, the CR has a number of new functions readily available on no other computer, making it the most useful instrument for modern-day piloting needs. The wind side of the CR uses a wind triangle that is rather different than the E6-B and it provides quick, streamlined options to all course navigation issues. The larger CR-6 provides optimum readability while the smaller sized CR-3 and CR-4 designs provide benefit. Just apr's computers have the special apr Microset that permits the computers to be aligned for overall accuracy prior to leaving the factory. Although they are accuracy instruments you will take pride in owning, the information they offer you is only as great as the information you offer them. For this factor, we advise you take the time to study this manual carefully. Our CR computer is bought by the U.S. Government under the identifying description of NSN 1R 6605-00-928-4552 UX. Calculator The calculator side of the CR computer is developed for quick, accurate computation with issue addressing capabilities adapted to existing air travel needs. Wind Computation The wind-computing side of the CR computer uses the lastest "advanced" innovation. With this new instrument your pre-flight and in-flight computations are easier and more accurate.
The wind side of the CR provides quick, simplified solutions to all course navigation problems.
Exclusive Microset that allows the computers to be aligned for total accuracy.
