The CR Computer has been a favorite of professional pilots, navigators, and flight engineers for approximately 20 years. If you began your flying career with the basic E6-B type computer you will find both similarities and important differences between the E6-B and the CR Computers.

Once you become familiar with the CR computer it will more than likely be your favorite cockpit aid. Many of the scales on the calculator side are similar to those found on the E6-B. However, the CR has several new functions available on no other computer, making it the most useful instrument for modern piloting needs. The wind side of the CR uses a wind triangle that is somewhat different than the E6-B and it provides quick, simplified solutions to all course navigation problems.

We offer three models of the APR CR computer. The larger CR-6 provides maximum readability while the smaller CR-3 and CR-4 models provide convenience. Only apr’s computers have the exclusive apr Microset that allows the computers to be aligned for total accuracy before leaving the factory. Although they are precision instruments you will take pride in owning, the information they give you is only as good as the information you give them. For this reason, we recommend you take the time to study this manual carefully.

Calculator
The calculator side of the CR computer is designed for quick, accurate computation with problem solving capabilities adapted to current aviation needs.

Wind Computation
The wind-computing side of the apr CR computer applies the lastest "state-of-the-art" technology. With this new instrument your pre-flight and in-flight calculations are easier and more accurate.

This CR-4 computer is purchased by the U.S. Government under the identifying description of NSN 1R 6605-00-928-4552 UX.

The APR CR-4 is comparable to the Jeppesen CR-2 computer. Made with PVC Plastic 4-1/4" Diameter.

Old School Still Works

  • By Greg from Champaign IL USA on Tuesday, May 29, 2018
  • Pros: One-handed use, compact size, "accident" proof
  • Review: It never needs batteries. If you drop it or it gets wet, it still works.

    Seriously, it is more compact than the E6B and the wind correction functions are not difficult, just different than those of the E6B. The yellow background color makes the CR easier to read. The instruction booklet is well written and even has test problems (with answers) at the end.

Great product

  • By Albert from Longwood FL USA on Thursday, March 03, 2016
  • Pros: Fits easily in my flight bag.
  • Review: I've used this computer for over 30 years and still have the original.
