authorizing t he use of the open SID concept. Open SID design criteria allow the use of RNAV departures with manual ter mination legs with the option to rejoin the RNAV route. o This is a design that should only be used operationally necessary to achieve airspace efficiencies. Think of it as joining the procedure off the runway to a certain point, then radar vectors to clear airspace or traffic and then rejoining the procedure later on. o This helps in areas where aircraft that outperform minimum climb criteria (most aircraft) in not being tied down to a longer OTG procedure. Next steps: There are 5 things in T ARGETs that need t o be revised. o There are RNAV departure software changes, criteria engine chan ges and the actual new release. This will take to the end of October for testing. o Other concerns are training and testing in STARs equipment and ERAM for automation. Contact me if you want a copy of the memo, which contains the details of the procedure design. • PBN Strategy PARC Action Teams - There are 6 of these and here is a summary of what's happening on some: o Mixed Equipage – How are we going to deal with this in the future as it appears we will always have this problem, which presents us with different performance characteristics. Issues to consider are: DME – Aircraft/Avionics capabilities, the concept of Voluntary Equipage, and how operations would continue during a GNSS outa ge for aircraft not equipped with DME or IRU. Policy – making sure that the policy implications are known and that plan is in place to address. It seems to be implied that best equipped/best served is the goal but there is no policy for it. o Military – How to accommodate DoD operations in the future operating environment when they are not likely to be equipped. o Use of LPV requirement is currently in the PBN strategy for the Far Term and is it needed or achievable because most airlines are not equipped. • Circl ing minimums – Circling approaches and lines of minima are considered unnecessary and a burden at smaller airports due to cost of maintenance, the lack of use by airlines, operational complexity, and their inherent instability when compared to straight - in approaches. o The proposed strategy of straight - in PBN approaches to each runway end could make circling unnecessary at these airports and allow the total removal of circling minima. This proposal would affect 138 NSG 1 and 2 airports and 376 airports classi fied as NSG 3. o A total of 514 airports meet the criteria of having at least 2,500 enplanements and are recommended for having all circling approaches removed by 2025. The problem is that there are still training requirements, resiliency needs, airport acce ss and obstacle clearance advantages, so we have to be careful about how many of these disappear even though on the surface it looks very easy to get rid of these for the aforementioned reasons. o Recommendation: Add in 2015 - 2020 Timeframe Removal of circlin g approaches from Navigation Service Group airports in accordance with criteria developed by the National Procedures Assessment
