Do ATC displays show the target altitude that the pilot has set in the autopilot? When cleared to climb/descend to a level, the pilot enters that level in an altitude preset window, allowing the autopilot to climb/descend and level off at that level. Is this level, preset by the pilot, visible on an ATC radar screen?
Yes, our radar is indeed capable to display data of the Mode S Enhanced Surveillance Transponder like Selected altitude, IAS, Mach Number, Heading and more.
After issuing a climb/descend clearance and entering it into the sytem it would also warn us if the selected altitude is different from the cleared level.
