OK, let's try it this way...
It all started with the Tenerife disaster. Now that one had little or nothing to do with ground control. However
, since then the FAA has gone out of thier way to "educate" pilots about runway incursions backed up by punishment incentives.
So here we are 40 years later and incursions still occur at about the same number every year. From that I conclude that the FAA's Solution
has been about as effective as facing into the wind while trying to relive oneself.
So do we continue to pound pilots into the ground or do we pull our head out the box and look elsewhere? In most companies a failed solution as well as the author of it would be standing at the curb with their belongings, and a lot sooner than 40 years
What else can be done?
In the 70's at Bowman Field, KY they used colored lines to help locate the taxiways. Taxi to Rwy 33 via Hotel, Juliet and Echo, following the red marking line.
(color vision a must)
Ground Surveillance Radar - I have been give taxi headings in some places until established on the taxiway.
ADS-B seems to hold a possibility. Couple that with an automated computer ground controller...
But in all cases SOMEONE has to be looking at it. So why not have the Ground Controller tasked to look out the window until something better comes along? Again, 'workload' is an excuse not an answer.
