situations only. Permanent lighting within the unserviceable area shall be masked. This includes green taxiway lighting situated within the runway and visible from the
approach direction. 4.5.4.5 Reasons For Closure of Movement Area
Reasons that justify closure of specific facilities include: Runway
• Runway surface flooding • Pot holes in the runway or runway strip surface
• Deep erosion in the runway strip surface • Obstacles on the runway or runway strip surface or infringing the associated
approachtake-off surfaces • Loose stones or other debris on the runway surface with immediate clean up
delayed • Excessive bird activity on a particular runway or within the approachtake-off areas
of that runway • Or any other reason which may affect the safety of aircraft operations i.e. full or
partial loss of lighting system Note: In determining whether a temporary threshold canshould be used instead of a
full runway closure, consideration will need to be given to the length of the remaining serviceable portion seek airline advice regarding useable lengths, and windtraffic
conditions at the time and the usability of the other runways seek ATC advice. Normally, any condition that renders the graded portion of runway strip unserviceable,
also renders the runway unserviceable. Taxiways and Aprons
• Surface flooding • Pot holes in surface if beyond the scope of immediate maintenance
• Deep erosion of the taxiway strip surface • Loose stones or other debris covering the surface immediate maintenance
delayed • Soft surface
• Immovable obstacles • Fuel or oil spills
• Or any other reason which may affect the safety of aircraft operations i.e. full or
partial loss of lighting system Note: In addition to an unserviceability of the movement area, any unserviceability or
damage to the T-VASIS system or visual ground aids that cannot be readily rectified is to be reported. A NOTAM may be required. For details of the correct reporting.
