Initially, I thought they are safe ground clearance altitude. And they are not transition alt either ![ScreenShot_2025-11-15_004443_924](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/3X/5/4/546cef71249d30ab22b2bfae3c5e2a5169d17b5c.jpeg) ---

HI Danielle, These are MORA - Minimum Off-Route Altitudes: _The MORA is the lowest altitude that provides guaranteed clearance from all terrain and obstacles within the grid square boundary. This is a crucial safety feature for pilots, especially when flying in instrument meteorological conditions (IFR) or as a general safety check during visual flight rules (VFR) flights, ensuring vertical separation from the ground._ See also Page 7 of [https://download.navigraph.com/docs/guides/charts/introduction\_to\_navigraph\_charts.pdf](https://download.navigraph.com/docs/guides/charts/introduction_to_navigraph_charts.pdf). We are working on a project to make such information more immediately accessible to our users. Cheers Ian
