3) Start to incorporate a ranking system for each sign submitted. The manufacturer would have to rank each of the signs they submit as 1, 2, 3, etc.. With 1 being the most important.
If we get more than eight signs submitted we will have to limit
the number submitted per manufacturer to their most important.

2012 PCMS & FAP Meeting
FAP Testing Requirements
– Feedback from other States after 2011 annual meeting
The reason NTPEP data was not being used was because FAP sight test location was 4800’ versus 5280’ as stated in MUTCD
2012 PCMS & FAP Meeting
FAP Testing Requirements
– Originally due to the length of the runway we were limited to 4800’
– In 2011 due to FAA requirements the tree line on both side of the runway needed to be cut back
– The length of the runway plus additional field now measures one mile
