Procedure for ensuring pilots line up with the centre of the runway:
Having received and acknowledged ATC clearance to enter the runway in use, crews must ensure that the runway cleared for use is the same runway as the one to be entered. Visually aquire runway centre line. This can be determined by a centre line marking, or by finding a position equidistant from each edge of the runway. Line up with the centreline, making sure that the aircraft is aimed along the correct runway heading.
Pilots must ensure that the aircraft is not allowed to line up on the runway edge, which may cause damage to runway edge lighting.
There, backsides covered; is that better? The usual consultancy fee is required.
