Synopsis

A90 Controller described a confused SID assignment event when traffic had to vectored to ensure separation; the Reporter commenting that new RNAV SIDS are causing confusion and that new verification procedures should be implemented.

Narrative

Air Carrier X departed Runway 09. Aircraft was flight planned over NELIE intersection and the FDIO strip indicated the PATSS1 departure appropriately in box 10; per BOS SOP and BOS/A90 LOA. Upon reaching the vicinity of GLLET the aircraft failed to turn westbound; as per the procedure; and began to continue southbound. The trainee on position; realizing that this was incorrect; immediately issued a vector to the west. This submitter then took over the position to verify which SID the pilots were flying. The pilot stated that they were flying the SSOXS1 departure. The flight received an IFR clearance via PDC so we asked them to verify the procedure on their clearance printout. They stated the PDC indicated SSOXS1. If Air Carrier X had been NORDO; the aircraft would have gone to SSOXS and then turned westbound; potentially conflicting with arrivals to BOS from over PVD. Boston now has 8 SIDs published. Six of the SIDs are RNAV procedures that were developed to meet noise abatement wishes of the surrounding communities. All six of these procedures are dependent on the direction (routing) the aircraft will exit A90 airspace; not which runway the aircraft departs. These procedures were published in the Fall of 2009; however were not put to use until February 1; 2010. The only indication a controller has of which procedure was issued to the pilot is a single letter written in box 10 of the FDIO strip. There is no requirement for BOS ATCT to verify that a pilot has received the correct SID (routing). After one month of these procedures being used; and numerous and various errors surrounding the use of them; there continues to be no requirement for BOS ATCT to verify with the pilot that the correct SID (routing) was issued and received. A90 controllers have no confidence in these procedures. Anticipated separation can no longer be used and this submitter has resorted to applying vertical separation primarily because lateral separation cannot be guaranteed. Recommendation: 1. BOS ATCT must be required to verify with pilots the receipt of proper SIDs. 2. Required JO 7110.65 takeoff clearance phraseology should be amended to include RNAV SIDs. ex.; Air Carrier X; after departure fly the PATSS1; runway niner cleared for takeoff. 3. Pilot phraseology on departure should include call sign; SID name; and altitude verification information. 4. Currently; each of 6 RNAV SIDs at BOS are designed to serve 5 different runways to an exit fix. RNAV SIDs at BOS should be redesigned to be runway dependent with transitions to the proper exit fixes.

Frequently asked questions

How do I search flights by aircraft type on FlightFinder?

Pick an aircraft model — Boeing 737, Airbus A320, A380, Boeing 787 Dreamliner and more — enter your origin airport, and FlightFinder shows every route that plane flies from there with live fares.

Which aircraft types can I filter by?

We support Boeing 737/747/757/767/777/787, the full Airbus A220/A319/A320/A321/A330/A340/A350/A380 family, Embraer E170/E175/E190/E195, Bombardier CRJ and Dash 8, and the ATR 42/72 turboprops.

Is FlightFinder free to use?

Search and schedules are free. Pro ($4.99/month, $39/year, or $99 one-time lifetime) unlocks the enriched flight card — on-time stats, CO₂ per passenger, amenities, live gate & weather — plus My Trips with push alerts.

Where does the route data come from?

Live schedules come from Amadeus, AeroDataBox and Travelpayouts. Observed routes (which aircraft actually flew a given city pair) are crowdsourced from adsb.lol ADS-B data under the Open Database License.
