NEW SMYRNA BEACH MUNICIPAL AIRPORT AIRPORT MASTER PLAN UPDATE

APPENDIX A

Glossary of Terms:

47 CFR Parts 0 – 70 (Parts 0-19 and 70-79) - All current parts of the Code of Federal Regulations governing telecommunications and licensing including organizations of the FCC, frequency allocations, construction of antennas, broadcast services, cable services and rules of operation.

A-WEIGHTED SOUND LEVEL (dBA) - The ear does not respond equally to sound frequencies. It is less efficient at low and high frequencies than it is at medium or speech-range frequencies. Thus, to obtain a single number representing the sound level of a noise having a wide range of frequencies in a manner representative of the ear’s response, it is necessary to reduce the effects of the low and high frequencies with respect to the medium frequencies. The resultant sound level is said to be A-weighted, and the units are decibels (dB); hence, the abbreviation is dBA. The A- weighted sound level is also called the noise level. Sound level meters have an A-weighting network for measuring A-weighted sound level.

AC (00/0000-0) - Advisory Circular (with an identification number) published by the Federal Aviation Administration (FAA) to provide specific information, instructions or standards established for aviation related subjects.

ACCEPTABLE (DNL not exceeding 65 decibels) - The noise exposure may be of some concern but common building constructions will make the indoor environment acceptable and the outdoor environment will be reasonably pleasant for recreation and play.

AIP - See AIRPORT IMPROVEMENT PROGRAM.

AIR CARRIER, CERTIFICATED ROUTE - An air carrier holding a Certificate of Public Convenience and Necessity, issued by the Federal Aviation Administration (FAA), to conduct scheduled services over specified routes and a limited amount of nonscheduled operations.

AIR CARRIER, COMMUTER - An air taxi operator who (1) performs at least five round trips per week between two or more points and publishes flight schedules that specify the times, days of the week, and places between which such flights are performed; or (2) transports mail by air pursuant to a contract with the U.S. Postal Service.

AIR NAVIGATION FACILITY (NAVAID) - A facility designed for use as an aid to air navigation, including landing areas, lights, any apparatus or equipment for disseminating weather information, for signaling, for radio direction-finding, or for radio or other electronic communication, and any other structure or mechanism having a similar purpose for guiding and controlling flight in the air or the landing or takeoff of aircraft.

AIR TRAFFIC CONTROL (ATC) - A service operated by appropriate authority (the FAA) to promote the safe, orderly, and expeditious flow of air traffic.

AIRCRAFT DELAY - The additional travel time, caused by aircraft congestion, taken by an aircraft to move from point A to point B.
