for a waiver will also slow down the dual and trip rules due to duplicate DCP process and save only two months, so the consensus seems to be to stay with a rule change that will eventually include everybody. o There are 4 or 5 airports pro posed for Potential TF implementation sites - ATL, CLT, SLC and SDF are among them. • National Procedure Assessment (NPA) – The 36 - page final report on the process and criteria for cancellation of instrument flight procedures that was approved by the Tactical Operations Committee in March 2016 is now out and available for those who want to see. • NSPP - ATL ZELAN3 special RNP SID delayed until 5/26/2016 publication cycle. ORD 9 STARs delayed until 9/15/16. • PBN on the ATIS – Conclusions from the latest Mi tre analysis: o Data analysis suggests that RNP approach availability advertised on ATIS can be an effe ctive measure to increase usage. The results also suggest that advertisement, alone, may not be effective everywhere and there are other factors contributi ng to usage rates . Other factors contribute to RNP approach usage, some of which are difficult to measure or attribute to the results, such as: Individual aircrew currency, daily demand timing that may drive ATC constraints or workload, operator initiative s to encourage RNP approach requests, controller comfort/fami liarity with the RNP operation. Next Steps: • Facilitate a coordinated ATC/airline effort to actively encourage use of RNP approaches at the study airports . • Consider increasing the number of airp orts in the study . • Measure and report on the effectiveness of these efforts. o Where successful and fleet mix/operations permit, consider advertising PBN approaches as the primary instrument approach. o RNP approaches may offer flight time/distance benefits i n some cases that serve as incentive for operators to request . o Straight - in RNAV (GPS) approaches offer no operational incentive for pilots to request such an approach when an ILS exists . o Not all aircraft can fly an RNAV (GPS) approach as a precision approach § Legacy CRJ and ERJ aircraft can only use LNAV line of minima . o We need to get input from the individual facilities in this initiative to see what they think and add to the analysis. Phase two , which expands this program , is next. • Performance Based Navigation Aviation Rulemaking Committee (PARC) – There is a new RF display action team: An NBAA letter to the PARC SG brought up an issue with RF leg utilization in some systems that cannot displa y the RF leg arc on their maps. These systems can "fly" the RF, that is, the navigation system can compute them and guide to them, but the display systems do not support displ ay of arcs (this is a problem). The letter summarizes the difficulty of ev en upgrading some of these systems, and asks for a review of possible operational mitigations that might be used to allow such systems to fly the RFs despite the display limitation. The SG made a decision to form an action team (AT) to tackle the issues br ought up by NBAA.
