An Essential navigation Protractor — for nautical maps

The clear, sturdy FlyGA Square Map Navigation Protractor (square design) is an essential tool that will assist you in plotting journeys using topographical charts throughout your experience as a pilot or captain. The traditional 128mm square design fits perfectly into flight bags.

This classic Square Aviation Protractor is very popular at flight schools, and often preferred over the alternative circle design. It’s regularly used by aviation students studying towards their Light Aircraft Private Pilot Licence (LAPL), Private Pilot Licence (PPL-A or PPL-H or Commercial Pilot’s Licence (CPL) under the EASA syllabus. It’s an equally useful protractor for marine, boating and sailing navigation.

The Square Aviation Protractor is often bought in conjunction with the Nautical Mile Scale Map Ruler. Note that orders surpassing the £20 threshold benefit from Amazon’s free delivery — making our aviation protractors the best value option on the market.

Product Care Information


Just like on fine wood and metal, the surface of your new acrylic piece must be protected from scratches and harmful agents. We use a very thin film which has been applied to the face of each product we produce, if your product becomes unreadable or ‘very scratched’ using your nail on the front corner, you can remove this film. (Note: these products are reverse printed therefore, do not try to scratch the back of your product)


Dust only with a soft damp cloth or chamois, wiping gently.


Use a good polish for acrylics. This cuts down on the dust that can be attracted to acrylic.

Scratch Removal

Because each product is made from high quality acrylic, this material can be scratched. But unlike most other materials, a scratch on this surface can be removed.
