FEAST Dynamic Radar Conflict Management 3

Question 1

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

Accepted Answer

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

Answer

The point where two aircraft are so close that separation is no longer possible

Answer

The moment TCAS issues resolution advisories to both aircraft

Answer

The speed-distance point where no heading change can avoid the conflict

Question 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?

Accepted Answer

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

Answer

Approximately 2 minutes — only the faster aircraft's rate matters

Answer

Approximately 1 minute — the combined rate is 2,000 ft/min

Answer

Approximately 3 minutes — closure rate of 500 ft/min because they are both on same track

Question 3

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

Accepted Answer

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

Answer

Turning it toward the conflicting aircraft so they pass each other more quickly

Answer

Issuing an incremental 10-degree heading change and monitoring the effect

Answer

Turning it 90 degrees to stop it moving toward the conflict area

Question 4

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

Accepted Answer

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

Answer

Override the TCAS advisory with ATC instructions to maintain separation responsibility

Answer

Ask the pilot to confirm the RA type before acknowledging

Answer

Instruct the pilot to ignore the RA and follow ATC instructions

Question 5

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

Accepted Answer

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

Answer

Turning one aircraft right and the other left to maximise divergence speed

Answer

Climbing one aircraft and descending the other simultaneously

Answer

Reducing the speed of both aircraft to reduce closure rate

Question 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:

Accepted Answer

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

Answer

An immediate emergency requiring an STCA-level response

Answer

Resolved — 8 NM is sufficient and no further monitoring is needed

Answer

A conflict requiring immediate heading change issuance
