CRP-6 Aviation Navigation Plotting Ruler for Pilots
CRP-6 Aviation Navigation Plotting Ruler for Pilots
Plan Your Flight Routes with Precision
The CRP-6 Aviation Navigation Plotting Ruler is an essential tool for pilots who rely on physical aviation charts for flight planning. Featuring a double-sided scale design and a rotating azimuth disc, this clear plastic ruler makes heading calculations, route plotting, and distance measurements fast and accurate — whether you're preparing for a cross-country flight or a training exercise.
Made in Mainland China.
Key Features
- Double-Sided Scale Design: The front side features a 1:500,000 sectional scale, while the back carries a 1:1,000,000 WAC scale — allowing seamless alignment across different aviation chart types without switching tools.
- Rotatable Azimuth Disc: A central rotating circular azimuth disc (9.8 cm diameter) lets you quickly calculate headings, track courses, and align with true north with minimal effort.
- Highly Legible Markings: At 33 cm long and 11.2 cm high, the ruler is printed on both sides with fine, clearly readable measurement markings to ensure pinpoint accuracy in route and distance calculations.
- Sturdy Plastic Construction: Built from durable, lightweight plastic with a 6.3 cm wide body, this ruler holds up to frequent use during intensive flight planning sessions without warping or fading.
- Pilot-Specific Design: Tailored for flight planning, heading measurement, course tracking, and distance plotting on sectional and WAC charts — a must-have for student and licensed pilots alike.

Frequently Asked Questions
Q: What chart types is this aviation navigation ruler compatible with?
A: The CRP-6 plotting ruler features a 1:500,000 sectional scale on the front and a 1:1,000,000 WAC (World Aeronautical Chart) scale on the reverse, making it compatible with the two most commonly used physical aviation chart formats for VFR flight planning.
Q: Is the azimuth disc on this plotting ruler fixed or movable?
A: The 9.8 cm azimuth disc is fully rotatable, allowing pilots to easily orient headings, align true north, and calculate course bearings directly on their charts during pre-flight planning.
Q: Is this ruler suitable for student pilots?
A: Absolutely. The CRP-6 aviation plotting ruler is an excellent tool for both student and licensed pilots. Its clearly printed dual-sided scales and rotating azimuth disc make it straightforward to learn and use for flight planning, heading calculations, and route tracking on paper aviation charts.
