This Letter to Airmen identifies noise sensitive areas in the vicinity of Danbury Airport and describes procedures to minimize noise impact in these areas.  These recommended practices were identified in a Noise Compatibility Study, and we encourage your compliance with these practices.  Voluntary cooperation may prevent the need for regulations on this subject.  Attachments 1 and 2 depict recommended departure paths to avoid close in noise sensitive areas.  Attachment 3 depicts all known noise sensitive areas within a five mile radius of Danbury Airport.

The following recommended procedures were identified in the Noise Compatibility Study:

1. When departing runway 8, turn crosswind at or above 1200’ MSL.

See attachment 1.

2. When departing runway 26, turn to crosswind as soon as possible, consistent with safe aircraft operation.  See attachment 1.

3. When departing runway 17, turn crosswind south of the Lake Waubeeka community.  See attachment 2.

4. When departing runway 35, turn crosswind at the Route 84 intersection.  Turn base for runway 35 south of the Lake Waubeeka community.  See attachment 2.

We are confident that you are concerned, as we are with the ecological and environ- mental conditions surrounding our airports.  Your help in this matter will aid in promoting a harmonious relationship with our airport neighbors.

Any questions should be directed to Danbury Tower at 203-748-6375.
