  1. A conflict alert (CA) is triggered when the computer predicts a loss of separation within how many minutes?

    Answer: 2 minutes

    The Conflict Alert (CA) automation typically predicts a loss of separation within 2 minutes to give controllers sufficient response time.

  2. An aircraft is assigned FL350 but the pilot reports unable due to turbulence and requests FL310. Another aircraft is at FL310 on the same route 15 miles ahead. The controller should:

    Answer: Both B and C could be correct depending on radar separation achieved

    The controller can approve FL310 only after ensuring 5-mile radar separation is established or can be established, which may require coordinating speed or routing.

  3. In ATSA collision simulation testing, what skill is primarily being evaluated?

    Answer: Ability to detect and resolve developing conflicts before separation is lost

    The collision simulation portion of the ATSA evaluates a candidate's ability to scan for, identify, and resolve conflicts among multiple aircraft.

  4. Two aircraft are at the same altitude; Aircraft 1 is southbound at 360 knots and Aircraft 2 is northbound at 420 knots. They are currently 40 miles apart. How many minutes until they would meet without intervention?

    Answer: 3.1 minutes

    Combined closing speed is 780 knots; 40 miles ÷ 780 knots × 60 min ≈ 3.1 minutes.

  5. Which statement about altitude assignments for conflict resolution is correct?

    Answer: Either climbing or descending may be used, based on traffic and efficiency

    Controllers choose the most efficient resolution based on all factors including traffic density, weather, and aircraft performance.

  6. A pilot on a VFR flight plan is observed on radar on a collision course with an IFR aircraft. The controller should:

    Answer: Issue safety alerts to both aircraft regardless of flight rules

    Controllers are required to issue safety alerts to all aircraft under their jurisdiction and those in their coverage area when a hazard exists.

  7. When multiple conflict alerts appear simultaneously on a radar display, a controller should prioritize based on:

    Answer: Time to conflict and severity of the loss of separation

    Conflicts with the least time remaining and greatest severity receive first attention to prevent the most imminent collision.
