Overview of TP312 5th (draft) Visual Aids

Installation Tolerances Terminology used; Distance range… Ex. Location / length / width of aiming point marking. “Not more than…” Ex. Edge light spacing “± “X” cm, m” Ex. Marking width, approach light position, inset light position “Above grade” Ex. Edge light break point height RDIMS 9056144

Markings (General) Editorial clarifications Black highlighting in a Note Apron safety markings a standard Limited used of red marking Striated markings moved into respective standards RDIMS 9056144

Lighting General Frangibility Weight bearing (inset) General Elevation of all edge lights (runway, taxiway, apron) RDIMS 9056144

Approach Lighting Systems General Same application - SSALR CAT I, ALSF-2 CAT II/III Any other system in accordance with standards Plane of lights standard Elevation of approach lights on strip end Transportation corridor clearances Clarified purpose of Aeronautical Evaluation determine the height of the most critical obstacle

PAPI / APAPI Application Non standard approach slope Threshold displacement > 48 hours LAHSO Risk assessment RDIMS 9056144

Taxiway Edge Lights Changes Required on curves for operations below RVR600 Spacing on curves (minimum 3 lights) Longitudinal spacing Limited use of double blues RDIMS 9056144

Unserviceability Lights Clarification of use of red lights Bridge Closed areas 3m spacing 10 cd minimum Non illumination of light on temporary closures, except for maintenance. Removal of lights on permanent closures RDIMS 8905261
