The FAA has approved most elements of the noise-compatibility program (NCP) for Martin County Airport/Witham Field (SUA) in Stuart, Fla. Approved components include preferential use of Runway 12 during calm winds, voluntary use of straight-out departure track for jets departing from Runway 12, a voluntary left turn to 285 degrees for jets departing Runway 30, a ban on Stage 1 aircraft and a voluntary Stage 2 nighttime curfew between 10 p.m. and 7 a.m. The FAA also endorsed the county’s plan to install equipment to record the actual flight tracks of aircraft using the airport to help monitor the effectiveness of the NCP. The FAA also encourages jet operators to use NBAA’s or manufacturers’ noise-abatement procedures.
