It would be an excessive hassle for players that just want to drive airplanes when they're off-road or in the desert or any unoccupied areas to spawn their planes and recover them.
Perhaps the developers could make it so this restriction can only happen in LS or LV (where gang wars take place). So then you can still do your thing in unoccupied areas, I doubt anyone will start flying an AT-400 or Andromada from a regular street.
If that restriction is exclusively for those 2 planes, then yes I vote positive. but if the devs decide to go for all planes, then nope.
