4 2012 PCMS & FAP Meeting Minutes of 2010 Meeting – Orlando, FL Minutes of 2010 Meeting – Orlando, FL - Action Items 2)Tennessee was going to look into the feasibility of testing truck mounted PCMS and FAP’s

5 2012 PCMS & FAP Meeting Minutes of 2010 Meeting – Orlando, FL Minutes of 2010 Meeting – Orlando, FL - Decision 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.

9 2012 PCMS & FAP Meeting Testing Timeline Testing Timeline January 17th Performance Testing February 17th Shutdown Testing March 19th Down Time March 28th Sight Testing March 28th

10 Due to the earlier submittal deadline Due to the earlier submittal deadline –Performance and Shutdown testing was completed a month earlier than normal. –The batteries were subjected to colder weather and less solar charging time due to shorter daylight hours. (Wanted a Worst Case Scenario) –Sight testing was completed three months earlier than normal PCMS & FAP Meeting

11 FAP Testing Requirements 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

12 FAP Testing Requirements 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 2012 PCMS & FAP Meeting
