• PBN delivers new routes and procedures that primarily use satellite‐based navigationand on‐board aircraft equipment to navigate with greater precision and accuracy. PBNis comprised of Area Navigation (RNAV) and Required Navigation Performance (RNP)and describes an aircraft’s capability to navigate using performance standards.

• RNAV is a method of air traffic navigation which permits aircraft to operate ondesignated flight paths with the use of ground and/or space−based navigation aids.

• RNP is an enhanced application of RNAV which enables flying more precise flight tracks,including curved paths, but requires additional aircraft avionics, FAA procedures, andpilot training and certification.

Potential Metrics

• Affected Population• Number of Noise Sensitive

• Frequency of Use• Number of Arrivals• Number of Departures • Average Noise Level• Other?

Potential Solution

Departure Procedures

Population density base layer allows for quantification of impacts and visually identifyingcompatible land use corridors.

Initial identification of Noise Sensitive Facilities included all health care facilities, firehouses, andchurches. A windshield survey will be conducted to enhance the reliability of the data.

Develop new PBN procedures to achieve greater adherence to Fly Quiet departure tracks which would result in fewer people impacted by nighttime departures.

Fly Quiet Rotation

42 ONCC Fly Quiet Committee Meeting #2

1. Establish a Rotation Plan that can be implemented to achieve the goals of the ONCC and meet the needs of the FAA and the CDA2. Fly Quiet Rotation applies during overnight hours when demand requires one arrival or one departure runway.3. Accommodate FAA requirements for maximizing safety and efficiency for various demand, wind and weather conditions.4. Accommodate CDA requirements for runway maintenance.5. Avoid the need to staff the north or south ATCT during overnight hours.6. Accommodate airline requirements for runway length.7. Strive to provide direct taxi routes and minimum taxi distances to reduce fuel burn and emissions.8. Provide an opportunity for balancing noise exposure by community on regular and predictable intervals.9. Provide a reasonable opportunity for communities to anticipate noise exposure over periods of time.10. Facilitate the ability to monitor and track the rotational program.

Fly Quiet Rotation Guiding Principles

Fly Quiet Rotation Options

43 ONCC Fly Quiet Committee Meeting #2

Option Description Considerations for Communities Operational Considerations Feasibility

1. Provides opportunity for more frequent rotation

1. More frequent rotation may capture seasonal variability better than less frequent rotation

2. Provides less wait time for next period of relief for some communities

2. May be more compatible with regular runway maintenance schedules

3. Provides less time in favorable configuration for some communities

3. More frequent rotation requires more frequent communication among parties for notification of changes

4. Weekly rotation schedule published in advance1. Provides opportunity for longer period within a given configuration

1. Less frequent rotation may not capture seasonal weather variability

2. Required longer wait time for next period of relief for some communities

2. Monthly rotation may be negatively affected by runway maintenance schedules

3. Provides longer time in favorable configuration for some communities

3. Less frequent rotation requires less frequent communication among parties for notification of changes

4. Monthly rotation schedule published in advance

Fly Quiet IIWeekly

Rotate preferred runway use plan and associated departure headings during overnight hours on a weekly basis, subject to operational

requirements

Fly Quiet IIMonthly

Rotate preferred runway use plan and associated departure headings during overnight hours on a monthly basis, subject to operational

requirements
