Max Allowed Altitude

[JacLavi]

In many (most of) countries rules and regulations exists about maxi altitude depending on the zone you fly. Here (FR_Fr) I believe absolute maximum is 150m. In my yard 25m. Most of the places even in the country the limit is 50m.

Current Behavior

Nowadays there are no parameters limiting the altitude the UAV can reach.

Desired Behavior

Add Inav a mean to forbid the UAV to climb over a limited altitude

Suggested Solution

Add a parameters the user can set via the Configurator.

Who does this impact? Who is this for?

Geonfence #4798 sounds good to me. Consider closing this one.

Redundants tickets ask for very sophisticated - maybe complicated - features. Will you just consider a (not so) simple max_alt ?
