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
