SAFETY AND TECHNOLOGY DEPARTMENT Week of Feb. 11 - 17: COLLABORATIVE DECISION MAKING (CDM) Kyle Andrews (ORD) is the NATCA Representative to the Surface Concept Team (SCT). Mr. Andrews fo rwarded the information below for the membership. The Surface Concept Team has no scheduled meetings or telcons for the month of February. The next telcon will be March 1, 2017, to discuss the latest CDM - SCT tasking, which is to engage industry and other users in the ongoing surface activity. The SCT will next meet in person at the CDM Spring Session in Dallas on April 11, 2017. NextGen Distance Measuring Equipment (NG DME) Program Samed Rizvi (PCT) is the NG DME National Representative. Mr. Rizvi forwar ded the information below for the membership. MITRE was tasked with providing a preliminary analysis of impacts on operational procedures due to the discontinuation of 135 DMEs not needed for the NextGen DME solution. The analysis examined procedures in w hich the stated DMEs were necessary in performing the procedure and focused on ILS, LO C, VOR, and VOR/DME procedures. The analysis found that 743 IAP s depict one or mo re of the 135 DMEs of interest. Out of these, 134 IAPs require the use of one of the 135 sites. 44 of the 134 a ffected IAPs will have mitigations from the VOR MON program , leaving 90 IAPs that may require separate action if DME discontinuation is pursued. Some of the mitigations would amend minima, amend the procedure, change the missed appro ach procedure, require GPS, or possibly cancel the procedure in its entirety. NextGen DME does not intend on pursuing the discontinuation of any DME s sites that are co - located with VORs that are being r etained by the VOR MON program. With that in mind, th e realistic number of a ffected DMEs that will have an impact on IAP s is between 50 - 60. MITRE's analysis did not include RNAV SIDs and STARs and they will be conducting an analys is of those as a separate task. There have been no determinations made on how to act on the results of the analysis. RNAV and PERFORMANCE BASED NAVIGATION (PBN) Bennie Hutto (PCT) is the Article 114 Representative for RNAV and PBN criteria work. Mr. Hutto's report for the membership is below. PBN Criteria Update: Pilot Controller Procedures & Systems Integration (PCPSI) A meeting was held January 30 - February 1 in Phoenix w h ere will discussed the following: Guided Visual Approach The PARC leadership tasked the Pilot Controller Procedures and Systems Integration (PCPSI) working gr oup to evaluate the "G uided Visual Approach" concept.
