Maps with big figures

[Yvezo]

Hello,
I updated the Plan-G version to 4.0.0.238.
Openstreet map is displaying big figures as described in the attached photo. exemple 12  08
These figures are not familiar to me. What are they used for?
They do not appear with a direct access on "openstreetmap.org"
How can I get rid of them?
Thank you for your answer.
Yves

Maximum Elevation Figure (MEF). Vital information for pilots. It tells you how low you can fly without hitting the ground. It's on all aviation maps.

If you *really* want to turn it off, there's a checkbox on the View tab.

Thank you for your reply,
I learned something today. This is one of the reasons I like flying.
On French VFR maps, however, you don't find this information as you describe it. Only highest points are shown.
I noted the MEP checkbox in the Plan-G view section. It's perfect.
