Definition

LALT: Low altitude operations - Collision or near collision with obstacles/objects/terrain while intentionally operating near the surface (excludes takeoff or landing phases).

Usage Notes

  • ‘Terrain’ includes: water, vegetation, rocks, and other natural elements laying, on or growing out of, the earth.
  • Includes ostentatious display, manoeuvring at low height, aerobatics, sight seeing, demonstration flights, aerial inspection, avalanche mining, human hoist or human cargo sling, search and rescue operations, aerial application, intentional helicopter operations close to obstacles during aerial work and scud running (ducking under low visibility conditions).
  • Also includes intentional manoeuvring in close proximity to cliffs, mountains, into box canyons, and similar flights where the aircraft aerodynamic capability is not sufficient to avoid impact.
  • If there is a loss of control during low altitude operations, both loss of control - inflight (LOC-I) and LALT are coded.

NOTE: excluding rotorcraft air taxi phase of flight.

NOTE: includes maneuvering at low height while searching for an off-aerodrome landing location.

Do not use LALT in conjunction with CFIT.
