NEW SMYRNA BEACH MUNICIPAL AIRPORT AIRPORT MASTER PLAN UPDATE
SOUND LEVEL METER - An instrument, consisting of a microphone, an amplifier, an output meter, and frequency-weighting networks, that is used to measure noise and sound levels in a specified manner.
TERPS - Certain airspace needs to be cleared for aircraft operations. This airspace is determined by the application of operating rules and terminal instrument procedures (TERPS). Removing obstructions to air navigation, except those that an FAA aeronautical study determined need not be removed, satisfies these requirements. Subpart C of FAR Part 77 defines obstructions to air navigation. (See FAA HANDBOOK 8260.3B)
TOWER - See AIRPORT TRAFFIC CONTROL TOWER (ATCT).
UNACCEPTABLE (DNL above 75 decibels) - The noise exposure at the site is so severe that the construction cost to make the indoor noise environment acceptable may be prohibitive and the outdoor environment would still be unacceptable.
VFR - See VISUAL FLIGHT RULES.
VFR AIRPORT - An airport without an authorized or planned instrument approach procedure.
VFR CONDITIONS - Weather conditions that permit aircraft to be operated in accordance with visual flight rules.
VHF OMNIDIRECTIONAL RANGE (VOR) - A radio transmitter facility in the navigation system radiating a VHF radio wave modulated by two signals, the relative phases of which are compared, resolved, and displayed by a compatible airborne receiver to give the pilot a direct indication of bearing relative to the facility.
VISUAL APPROACH - An approach to an airport wherein an aircraft on an IFR flight plan, operating in VFR conditions under the control of a radar facility and having air traffic control authorization, may deviate from the prescribed instrument approach procedure and proceed to the airport of destination, served by an operational control tower, by visual reference to the surface.
VISUAL APPROACH SLOPE INDICATOR (VASI) - An airport lighting facility in the terminal area navigation system used primarily under VFR conditions. It provides vertical visual guidance to aircraft during approach and landing by radiating a directional pattern of high-intensity, red- and white-focused light beams, which indicate to the pilot that they are on, above, or below the approach glidepath.
VISUAL FLIGHT RULES (VFR) - Rules that govern the procedures for conducting flight under visual conditions (Federal Aviation Regulations Part 91).
VISUAL RUNWAY - A runway intended solely for the operation of aircraft using visual approach procedures, with no straight-in instrument approach procedure and no instrument designation
