    A pair of navigation marks that, when in line, indicate to a pilot that the ship is on track.
    Leading marks
    Navigation lights and beacons that, when in line, indicate a vessel is on the right track
    Least material condition
    The minimum amount of material a part can have and still meet dimensional tolerances. For external features this is the lower tolerance (smallest allowable) and for internal features (ie, holes) this is the upper tolerance (largest allowable).

    Limit lines
    Lines marked on the surfaces of roadways to indicate places where road traffic is required to stop for the purpose of complying with traffic signs and signals, including railway level crossings.
    Limited Field of View (FOV)
    While FOV is limited, because NVGs are helmet-mounted the user can move their head to scan a wider area. The total area that can physically be scanned is called field of regard (FOR) and is mainly dependent on the physiology of head movement and cockpit design (eg, seat location, blind spots etc).
    Line
    The horizontal or lateral position of a track measured on both rails.
    Line flight
    A flight undertaken by a trainee with a training captain at the completion of line training, to assess whether the trainee meets the standard required to fly unrestricted with the operator.
    Line Service Manager (LSM)
    Manages and monitors the day-to-day train services across the rail network.
    Line training
    Line training is conducted for pilots new to aircraft types on operational flights by qualified training captains. The objective is for the pilots to achieve a level of competence to undertake line operations unsupervised.
    Linehaul Operations Manager (LOM)
    Manages day-to-day operations for locomotive engineers and operational issues.
    Liner service

    Load Line
    Mark indicating the maximum depth to which a ship may be safely loaded
    Lock-on frame
    A metal frame device that contains numbered locations where individually assigned padlocks are attached, to signify that a padlock owner is occupying the Danger Area within a PWA. Before the RPO authorises personnel to leave the safe place, they must attach their RPO padlock to the lock-on frame handle. All personnel and visitors on site must then attach padlocks for themselves before leaving the safe place, and padlocks for any vehicles under their control that will foul the track. When clearing the track for a rail movement (train), personnel must secure vehicles under their control in a safe mode, clear of the track, before returning to the safe place and locking off. After removing their padlock, personnel must not foul the track until they are authorised to resume work by the RPO. The requirement to use the system was contained in KiwiRail’s Track Safety Rule 902(g).
    Locking
    The process of placing or removing protection padlocks in accordance with KiwiRail’s track safety rules (see Appendix 4).
