noise abatement Airport sponsor published verified 2026-08-28 (42 d ago)

Published by the airport sponsor; voluntary unless ATC assigns it. If ATC assigns this route to you in Class B, C or D airspace, that assignment is an ATC instruction and compliance is required (14 CFR 91.123) — and “unable” remains available to the pilot in command.

Requested: no operations 2300-0700, reduce prop RPM as soon as possible after takeoff, limit APU use to 30 minutes.

The route

  1. All aircraft operators are asked not to operate between 2300 and 0700 local
  2. Propeller-driven aircraft should reduce prop RPM as soon as possible after take-off
  3. Limit auxiliary power unit usage to 30 minutes
  4. The airport has no power to penalise non-compliance — the FAA prohibits punitive action against a pilot who chooses not to use the voluntary procedures

[Airport FAQ:] Can the FMAA fine pilots who do not comply with the VOLUNTARY noise abatement procedures? No. The FAA prohibits the FMAA from pursuing punitive actions against a pilot who chooses not to use the voluntary noise abatement procedures.
Does the SUN have a curfew? No. In 1990 Congress passed a comprehensive airport noise statute called the Airport Noise and Capacity Act of 1990 (ANCA).
