Similar to how weapons are inactive while landing gear is deployed, or how countermeasures cannot be used when there is weight-on-wheels, the radar should be automatically disabled when the aircraft is on the ground. This is done on real-world aircraft to avoid microwaving ground crews standing nearby and would add a nice bit of immersion to the game if my radar would automatically activate/deactivate on take-off/landing. Another gameplay benefit is that it doesn't announce to any enemy medusas when you spawn in and they are inside your radar FoV.

I prefer manual control personally, it is nice to be able to do whichever is most convenient at the time. Using a Medusa as a makeshift ground radar does have its niche uses.
