ATLANTA TRACON LETTER TO AIRMEN NO. 11 - 4
SUBJECT:
ATLANTA HARTSFIELD-JACKSON INTERNATIONAL AIRPORT (ATL) REDUCED DIVERGENCE AREA NAVIGATION (RNA V) STANDARD INSTRUMENT DEPARTURES (S I Ds)
CANCELLATION: October 20 , 2013
Beginning Thursday, October 20, 2011, ATL will implement new Reduced Divergence RNAV SIDs. These SIDs have been designed to aid in noise abatement and add departure capacity to the ATL airport while ma i ntaining an equivalent level of safety when compared to existing separation standards. To achieve this, ATL will implement the Equivalent Lateral Spacing Operations (ELSO) standard developed by MITRE Corporation and approved for implementation by FAA Waiver I1-T-OS.
1. Reduced Divergence RNAV SIDs will be conducted daily between 0700-2300 Local Time . Between 2300-0700 Local Time, aircraft will be issued noise abatement radar vectors.
2. Pilots must ensure that they are operating on the current RNAV da t abase (dated 10/20/20 II or later) and that the correct departure runway is entered into the Flight Management Computer (FMC) prior to departure.
NOTE- Several fix/waypoints on the new SIDs are new or have moved from their previous location .
3. ATL controllers will issue departure clearances to RNA V aircraft using the "RNAV to" phraseology. Example - "DALl23, RNAV to SNUFY, Runway 26L , Cleared for Takeoff." I n this case, SNUFY would be the first named fix/waypoint on the SID to be flown. The pilot is expected t o verify that the fix/waypoint displayed on the Flight Management System (FMS) corresponds to the fix/waypoint issued in the departure clearance. If the fix/waypoint is not identical, pilots must request a vector from the Tower.
4. Advise ATC immediately of any RNAV anomaly and request vectors as necessary.
5. Extra vigilence is required in order to ensure the highest level of safety. The ATL Reduced Divergence RNAV SIDs commonly use divergence less than 5-degrees as depicted in Figure #1 and #2 (attached.) Departure tracks may be separated by as little as 10-degrees.
