Description

Loss of separation between aircraft sometimes occurs as a result of an aircraft deviating from the cleared track without clearance.

Loss of separation may be either in a vertical or a horizontal plane, or both.

Effects

  • Injury, especially to cabin crew or passengers, may result from violent manoeuvres to avoid collision with other aircraft or the ground.


  • High levels of stress for the pilots and controllers involved, which may lead to reduced performance.

Defences

  • Onboard aircraft equipment designed to warn of potential collision with other aircraft (TCAS).

Typical Scenarios

  • Pilot fails to follow ATC clearance or delays their actioning of an accepted clearance.
  • Pilot receives a TCAS RA but fails to follow it correctly.

Contributory Factors

  • Weather (e.g. thunderstorm activity).
