NOTE: ATM includes all of the facilities, equipment, personnel, and procedures involved in the provision of State approved Air Traffic Services.

 BIRD (BIRD)

Occurrences involving collisions/near collisions with bird(s)/wildlife.
Usage Notes:
.  May occur in any phase of flight.

NOTE: Bird strikes were previously categorized as “other”.  Users may wish to update their historic data by replacing “other” with “BIRD” where the occurrence involved a bird/wildlife strike.

CABIN SAFETY EVENTS (CABIN)

Usage Notes:
.  
Includes significant events related to carry-on baggage, supplemental oxygen, or missing/non-operational cabin emergency equipment.

.  
Includes inadvertent deployment of emergency equipment.

.  
Includes medical emergency for a person other than a flight crewmember or a medical evacuation patient.

.  
Excludes turbulence and other weather-related events, which are covered under TURB, ICE, or WSTRW respectively.

COLLISION WITH OBSTACLE(S) DURING TAKE-OFF AND LANDING

(CTOL)

Collision with obstacle(s) during take-off or landing whilst airborne.
.  
For all aircraft (excluding rotorcraft), to be used only in cases where the crew was aware of the true location of the obstacle, but its clearance from the aircraft flightpath was inadequate.

.  
Includes contact with obstacles, such as vegetation, trees and walls, snow drifts, power cables, telegraph wires and antennae, offshore platforms, maritime vessels and structures, land structures and buildings.

.  
Includes collisions during take-off to and landing from the hover. 

.  
Includes water obstacles during take-off from water (e.g., waves, dead-heads, ships, swimmers).

.  
Not to be used for occurrences classified under CFIT, LOC–I or SCF–PP.

CONTROLLED FLIGHT INTO OR TOWARD TERRAIN (CFIT)

.  
CFIT is used only for occurrences during airborne phases of flight. 

.  
CFIT includes collisions with those objects extending above the surface (for example, towers, trees, power lines, cable car support, transport wires, power cables, telephone lines and aerial masts). 

.  
CFIT can occur during either Instrument Meteorological Conditions (IMC) or Visual Meteorological Conditions (VMC).

.  
Includes instances when the cockpit crew is affected by visual illusions or degraded visual environment (e.g., black hole approaches and helicopter operations in brownout or whiteout conditions) that result in the aircraft being flown under control into terrain, water, or obstacles.

.  
If control of the aircraft is lost (induced by crew, weather or equipment failure), do not use this category; use Loss of Control – Inflight (LOC–I) instead.
