Shouldn't an Airfield Operations vehivle escort an aircraft instructed to cross a red stop bar to enter a runway?
@ Musket: What for?
How about a simple red / green traffic light at a runway holding point for control of non-radio vehicles.
@ LXGB
A pretty dangerous situation....
1. There should be no conflicting signals - if there is a traffic light in addition to the stopbar, they should be connected and should always show the same message.
2. Why having a traffic light there - colocated with a stopbar? The driver of the non-radio car could also watch the stopbar - could'nt he?
3. Who wants to have a vehicle without radio cintact on the TWY / RWY?
4. Furthermore - I would imagine that a traffic light on a pole is quite an obstacle on the edge of a TWY / RWY.
