EASA NAV(A)basic
Which map projection is standardly used for mid-latitude regional aeronautical charts (such as ICAO 1:500,000 navigation charts) due to its conformal properties and near-straight representation of great circles?
Answer
Lambert conformal conic
Explanation
The material identifies the Austrian Aeronautical Chart as using a **Lambert conic projection**. This is a conformal projection suited to regional charting. **Key takeaway:** The Austrian chart projection stated here is Lambert conic. **Glossary:** Lambert conic: a conic map projection that is conformal.
