Equip with RB-15f. While in air in NAV mode, place waypoints using radar fix Bx8, Bx7, Bx6. When you change waypoints, distance to them is also changed on waypoint range indicator, and waypoint name is also changed.
But when you change mode to Attack to launch RB-15f, changing waypoints shows changing range on indicator. But waypoint name indicator does not change. It stays with last waypoint, for example Bx8
