Red stop bar is one row of flush-mounted unidirectional red
lights installed across a taxiway with a 3m spacing to designate a runway
–holding position or intersection/taxiway holding position.
To prevent runway incursions, crew need to be trained and
instilled in adopting a disciplined approach in not crossing the red stop bar
even if ATC clearance is accorded.
Even in some cases where conditional taxi clearances are
given by ATC such as “cleared to lineup after the landing aircraft”, the taxi
shall be commenced only if the red stop bar light is off and the green centre
lights are switched on.
This is akin the red signal of the traffic light where the
traffic comes to a standstill. This holds good for operations in any part of
the world.
Good habit forming and disciplined procedural approach is the key to enhancing safety.
