  1. In radar conflict management, the 'point of no return' (PNR) refers to:

    Answer: The latest time at which a conflict resolution instruction can be issued and still restore safe separation

    The PNR is the last moment at which controller action can restore separation; after this point the situation can only be managed, not resolved by normal means.

  2. Aircraft Charlie is descending through FL250 at 2,000 ft/min. Aircraft Delta is climbing through FL230 at 1,500 ft/min. They are on the same track. The current vertical separation is 2,000 ft. Approximately how many minutes before they close to 1,000 ft?

    Answer: Approximately 0.29 minutes (about 17 seconds) — combined closure rate is 3,500 ft/min

    Combined vertical closure rate = 2,000 + 1,500 = 3,500 ft/min. Distance to close from 2,000 ft to 1,000 ft = 1,000 ft. Time = 1,000 ÷ 3,500 ≈ 0.29 min ≈ 17 seconds.

  3. When using a heading change to resolve a conflict, the controller should aim to turn the aircraft to achieve separation by:

    Answer: Turning it away from the conflicting aircraft to increase track divergence and ensure separation on current tracks

    Heading changes should turn the aircraft away from the conflict to create track divergence, increasing lateral separation and ensuring the tracks will remain separate.

  4. A controller receives a TCAS RA notification from a pilot. The controller's correct response is:

    Answer: Acknowledge the RA and do not issue any instruction that conflicts with the TCAS advisory

    When a TCAS RA is issued, pilots must follow it. Controllers must acknowledge and must not issue conflicting instructions until the RA is resolved.

  5. In a head-on conflict scenario, the fastest safe resolution method is usually:

    Answer: Turning both aircraft in the same direction by the same number of degrees — each turns right

    Standard right-hand turns for both aircraft (in the same rotational direction) ensures each pilot turns away from the other in a predictable way, creating maximum lateral divergence.

  6. A controller sees two aircraft converging at the same level with 6 minutes to CPA and currently at 8 NM separation (minimum 5 NM). The situation is:

    Answer: Not yet a conflict — separation is above the minimum — but the trend requires monitoring and early action planning

    At 8 NM with 5 NM minimum, separation is currently sufficient. However, the converging trend means it will reduce, requiring early planning and preparation for resolution.
