Ocean Routing Concept
The ocean routing concept approach utilizes extended climb paths for turbojets operating at low altitudes bringing the aircraft to higher altitudes prior to overflying urbanized areas. The revised departure procedures for this concept focus on Newark International (EWR) but affect John F. Kennedy International (JFK) and LaGuardia (LGA) flight procedures as well.
Newark departures from the south runways (22L/R) would fly over the Arthur Kill and Raritan Bay waterways and then turn east toward the Atlantic Ocean. Once over the Atlantic Ocean, eastbound traffic would turn left and proceed over Long Island, while south and west bound traffic would continue down the coast. Westbound traffic would turn right and cross land in central New Jersey, while southbound would continue on course. All traffic would be in a continuous climb and would cross land at altitudes of no less than 16,000 feet or higher.
Newark departures from the north runways (4L/R) would start a loop to the west after takeoff. North, Northwest, and Northeast bound traffic would proceed on course after partially looping to the west. The southbound traffic would continue the loop to the south, cross back over Newark airport, and pick up the procedures utilized for runway 22L/R departures listed above.
All of the procedures would require changes to standard departure procedures and rerouting of current traffic flows into the major metropolitan airports.
Requirements to accomplish this concept include:
- Moving JFK arrival and departure operations to the east
- Requiring a 400 foot/nm climb gradient for EWR runway 4L/R departures transitioning to a desired ocean route segment via Raritan Bay and the Industrial Waterway
- Providing course guidance in the Standard Instrument Departure procedures to tighten the dispersion of flight tracks
