Definition
The phase of flight in which the aircraft transitions from the air to the surface, comprising the final approach, flare, touchdown, and rollout to a controlled stop or taxi speed.
Plain English
Bringing the aircraft down from the air and onto the runway, finishing with the wheels on the ground and the aircraft slowed enough to taxi.
Context Anchor
Seen in abbreviated aviation text such as airport notices, flight information, charts, and operational messages where space is limited.
Derivation
LDG is a shortened written form of landing. Landing comes from land, meaning to bring something onto land or another surface; in aviation it means bringing the aircraft from flight onto its landing surface.
Why Pilots Care
Landing is one of the highest-workload phases; errors here cause a large share of accidents.
Intuition Check
LDG is not a different maneuver from landing. It is simply the shortened written form used in aviation messages.
Example Sentence 1
The pilot reviewed the LDG distance for the destination airport before departure.
Example Sentence 2
Strong crosswinds made the LDG more challenging than usual.
