LVP
Pronunciation: L-V-P
Also written as: LVP — Low Visibility Procedures
Low Visibility Procedures; a set of enhanced operational measures activated at an airport when visibility falls below specified minima.
Full Definition
LVP (Low Visibility Procedures) are activated by airport authorities when meteorological conditions—such as fog, mist, or heavy precipitation—reduce visibility and/or cloud base to levels that require additional safeguards for safe aircraft operations, including instrument approaches and ground movements. Under LVP, restrictions are placed on vehicle and aircraft movements on the manoeuvring area, additional lighting is activated, and enhanced ATC separation is applied. Editors working on aerodrome manuals must ensure that LVP conditions and associated procedures are described precisely, including the visibility and RVR thresholds that trigger each category.
Usage
Usage note: Always expand on first use in formal documents. LVP has distinct trigger thresholds defined in national regulations; editors should not generalise these without referencing the applicable authority.
