Found as a complete set; sold as shown.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWHAT WE KNOW\u003c\/strong\u003e\u003cbr\u003eJeppesen is the gold standard name in aviation navigation, and the CR series flight computers (circular slide rules) were standard equipment for student and professional pilots from the 1940s through the advent of electronic flight computers. The CR-3 and CR-5 differ in scale and application — the CR-5 is the larger, more capable model used for advanced navigation calculations. This set includes both computers, additional navigation tools, and original manuals with wear consistent with use; a name is written on the manuals. Sold as-is as a complete set. Functional status not independently verified.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTHE STORY\u003c\/strong\u003e\u003cbr\u003eBefore GPS and electronic flight bags, every pilot carried a flight computer. The Jeppesen CR was the instrument that translated weather data, aircraft performance, and route information into actionable numbers — wind correction angles, true airspeed, fuel required, time en route. Learning to use one was a rite of passage. A set like this, complete with manuals, is a working piece of aviation history.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWHY WE CHOSE IT\u003c\/strong\u003e\u003cbr\u003eThe CR-3 and CR-5 together make this a more complete and useful set than a single computer alone. The manuals add provenance and usability. A strong find for a student pilot, an aviation collector, or anyone drawn to the elegance of analog calculation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eABOUT THIS PIECE\u003c\/strong\u003e\u003cbr\u003eMaker: Jeppesen\u003cbr\u003eIncludes: CR-3 flight computer, CR-5 flight computer, additional navigation tools, original manuals\u003cbr\u003eCondition: Good vintage condition — wear to manuals, name written inside, computers intact.
