A Decision Support Scenario
• A soft control area– the collision risk between the airplanes is tracked– the altitude is controlled;
• A strict control area – a certain a landing procedure is assigned to the
curtain track– the constraints are followed.

Conclusions
• Human operator needs are satisfied– Improving situational awareness
• Only Essential terain obstacles– Reducing cognitive workload
• Aircraft position in respect of Ought to Be trajectory
• Lesson learned– From “What to draw” to “What not to draw”– Avoid of redudant details
