Lading. The placing of cargo, mail, baggage or stores on board an aircraft to be carried on a flight.

Unlading. The removal of cargo, mail, baggage or stores from an aircraft after a landing.

“landing area” means that part of the movement area intended for the landing or take-off of
aircraft

Landing direction indicator. A device to indicate visually the direction currently designated for landing and for take-off.

“Landing gear extended speed’ means the maximum speed at which an aircraft can be safely flown with the landing gear extended.

‘Landing gear operating speed’ means the maximum speed at which the landing gear can be safely extended or retracted.

‘Large aeroplane’ means an aeroplane of more than 5700 kg (12,500 pounds) maximum certificated take-off weight. The category ‘Large Aeroplane’ does not include the commuter aeroplane category.

Laser-beam critical flight zone (LCFZ). Airspace in the proximity of an aerodrome but beyond the LFFZ where the irradiance
is restricted to a level unlikely to cause glare effects.

Laser-beam free flight zone (LFFZ). Airspace in the immediate proximity of the aerodrome where the irradiance is restricted
to a level unlikely to cause any visual disruption.

Laser-beam sensitive flight zone (LSFZ). Airspace outside, and not necessarily contiguous with, the LFFZ and LCFZ where
the irradiance is restricted to a level unlikely to cause flash-blindness or after-image effects.

Landing distance available (LDA). The length of runway which is declared available and suitable for the ground run of an
aeroplane landing.

LDIN:   Lead-in lighting

Landing decision point (LDP) means the point used in determining landing performance from which, an engine failure having been recognised at this point, the landing may be safely continued or a balked landing initiated.
