Neighborhoods affected by this configuration would be:

Arrivals to Runway 6

Aircraft approach the airport off-shore of the South Shore, intercepting the final ILS approach course to Runway 6.  The recently installed ILS to Runway 6 is expected to bring added safety and noise abatement benefits.  In the past, with only one ILS approach available at Nantucket Memorial Airport, poor weather required the use of Runway 24, even on days when the wind would favor the use of Runway 6.  Now aircraft will have two ILS approaches available and either could be used depending on the prevailing wind at the time.  The ILS to Runway 6, being flown entirely over water, has obvious noise abatement benefits as well.

Departures from Runway 6

Departures, under FAA positive control, are directed either northbound, westbound or southbound depending on the aircraft destination.  About 80 - 85 percent of departing traffic will follow the visual noise abatement departure route to Folger's Marsh and Third Point.  Most northbound departing traffic on instrument flight plans, under positive control of the FAA, will be directed to turn northbound to a heading of 010 degrees after departure.  Some higher performance air carrier and twin jet aircraft will be directed to depart straight ahead toward Quidnet, Squam and Wauwinet before being directed northbound or southbound toward the aircraft's destination.

Figure 8b, below, shows landings and departures occurring on Runway 6. 
Good visual flight conditions exist.  All aircraft types will use Runway 6 for arrivals and departures.

 

Neighborhoods affected by this configuration would be:

Arrivals to Runway 6

About 75 - 80 percent of traffic arriving to Runway 6 in visual conditions will follow the 1-mile off-shore noise abatement routes paralleling the south shoreline and eastern shoreline to the airport.  Generally higher performance aircraft (twin jets and turboprops) will make a straight-in approach over-water to Runway 6. 

Lighter single engine aircraft, for safety considerations, have been exempt from the suggestion to remain 1-mile-off-shore and are integrated by Tower Controllers into spaces in the arrival stream.  Aircraft flying on Instrument Flight Plans are controlled by the Cape Approach Control facility and will arrive over-water, straight-in, to land on Runway 6.

Departures from Runway 6

About 80 - 85 percent of departing traffic will proceed visually to the Folger's Marsh departure checkpoint.  Other northbound and westbound departing traffic on instrument flight plans, under positive control of the FAA, will be turned on a northerly heading (010 Degrees) after takeoff.  Some higher performance jet and turboprop aircraft will depart straight ahead over the Quidnet, Squam and Wauwinet areas.
