Community Engagement – Maine, New Hampshire, Massachusetts

The Federal Aviation Administration is proposing an update to certain helicopter-specific air traffic procedures, known as the FAA Instrument Flight Procedures Low-Level Helicopter System (ILHS) to support Helicopter Air Ambulance (HAA), or the ILS-HAA Project:

  • This new suite of air traffic procedures will improve safety for helicopter air ambulance operations, by enabling them to fly with more predictability during inclement weather with air traffic oversight.
  • An Environmental Assessment (EA) will be conducted for noise impacts and other factors such as biological resources, environmental justice, and air quality. You may see the Draft EA here.
