I like the small USAF one. Basically a small E-6B for fighter/attack cockpit use.

I don't remember the designation, but I still have one around.

My favorite was the Jepp CR-5. Fits in a shirt pocket.

I had my primary students buy a CR computer, too, but most picked a larger size which was easier to learn on. The CR-3, I think.

I think the medium-sized CR-2 is the only one that they still make.

I have never, ever used the one all the GA folks have trained on; I started my Nav training on the CR-2 and still carry one to this day. On long legs I still use it to manually check all my great gadgets and remind myself of the navigator's fundamentals. Although it's most accurate the faster you go, and 160-172 knots TAS is NOT what I think they had in mind.

Best regards,

You really don't need 8-decimal place precision when calculating a flight plan. Those who used slide rules understood that. Those who grew up with electronic calculators; not so much.

This is the one I was issued in the USAF and when it was lost in the crash, I picked up a replacement from eBay.

Another site says 4" wide and 7.5" long, in the case.
