![]() The safe operation of airside vehicles depends upon drivers being adequately trained and thoroughly familiar with the aerodrome layout in all visibility conditions and on their compliance with procedures, signs, signals and ATC instructions. Airport ground charts which show hotspots arising from frequent or opposite traffic, pilot reports of confusion or bad signage may improve pilots and controllers situational awareness. This risk can only be managed adequately by the application of procedures that provide the pilot with clear, unambiguous guidance on routing and holding points or ground traffic patterns. The risk of inadvertent runway incursion by taxiing aircraft is greatest at aerodromes with complex layouts and multiple runway access points. If a rejected take-off ( RTO) is carried out, pilots must maintain awareness of runway length remaining using whatever external visual cues are available relevant runway lighting, signage or markings may be available.Īs visibility deteriorates, the potential for runway incursions by aircraft, vehicles or personnel increases. Low visibility take off also requires careful attention to correct runway alignment before the take-off is commenced an ILS LLZ signal can be used for verification if available. Making the necessary transition to visual reference during the final stages of an approach to land in poor visibility is critical and certain requirements must be met to reduce the risk of a Runway Excursion. The aircraft is likely to be badly damaged or destroyed if it collides, at high speed, with any sizeable object. An aeroplane on the ground is at its most vulnerable during the landing and the take-off phases of flight when the options for avoiding action, if an obstruction is encountered, may be very limited. On aerodromes where the ground marking and lighting is adequate, ground traffic at reasonable flow rates can often be sustained safely in reduced visibility. It should be noted that in the latter case, surface visibility may be relatively good but the TWR visual control room may be in cloud/ fog. Low visibility procedures exist to support Low Visibility Operations at Aerodromes when either surface visibility is sufficiently low to prejudice safe ground movement without additional procedural controls or the prevailing cloud base is sufficiently low to preclude pilots obtaining the required visual reference to continue to landing at the equivalent of an ILS Cat 1 DH/DA. Note that ICAO requires LVP for all departures below 550m RVR, not just LVTO. Low visibility take-off (LVTO) means a take-off with a Runway Visual Range (RVR) lower than 400 m but not less than 75 m. ![]() Low visibility procedures (LVP) means procedures applied at an aerodrome for the purpose of ensuring safe operations during lower than standard category I, other than standard category II, category II and III approaches and low visibility take-offs.
