Test Your Skills
In this skills test, you will be presented with a simplified ATC screen in which ten  aircraft are flying on designated flight paths [tracks] represented by a blue or a red line.
The Aircraft are depicted as green 'tear drop' shapes. The direction of the aircraft is established by the 'rounded' end of the shape. The speed and altitude of each aircraft is annotated in terms of Knots [Kts] and Flight Level [FL] respectively.
You will have 30 seconds to consider the scenario presented and indicate if apotential conflict exists between aircraft and if so, how many aircraft are in potential conflict.
For example, looking at the scenario below the correct response would be A: [2 aircraft are in potential conflict].
