Airport Environments: Airspace, Facilities, Markings, Lighting, Weather, and Noise

Controlled Airport

An airport with an operating control tower where ATC provides services and manages traffic.

Uncontrolled Airport

An airport without an operating control tower, where pilots coordinate among themselves.

Class A Airspace

Controlled airspace from 18,000 feet MSL up to and including FL600.

Class B Airspace

Controlled airspace surrounding the nation's busiest airports, typically requiring specific entry requirements.

Class C Airspace

Controlled airspace surrounding airports with a significant commercial presence and radar services.

Class D Airspace

Controlled airspace around airports with an operating control tower.

Class E Airspace

Controlled airspace that serves as a transition area for IFR operations, often starting at a specified altitude.

Class G Airspace

Uncontrolled airspace where ATC does not exercise control, typically low altitude.

Controlled Airspace

Airspace where ATC provides services, and communication/equipment regulations apply.

Traffic Pattern

The standard rectangular path aircraft follow around a runway during arrivals and departures.

Standard Traffic Pattern

Typically consists of upwind, crosswind, downwind, base, and final legs for aircraft.

Runway Designation Marking

Numbers on the runway indicating its magnetic heading.

Taxiway

Paths connecting runways, ramps, and terminals, improving traffic flow and safety.

Apron (Ramp)

The area of an airport where aircraft are parked, loaded, and serviced.

Hold Short Markings

Markings indicating where aircraft must stop before entering a runway environment.

CTAF

Common Traffic Advisory Frequency used at non-towered airports for pilot communications.

Visual Glide Slope Indicators (VASI/PAPI)

Lighting systems providing information about an aircraft's vertical descent during approach.

Running Incursions

Occurrences where an aircraft enters an active runway without clearance.

Runway Holding Position Marking

Markings with solid and dashed yellow lines indicating where to stop before a runway.

Fixed-Base Operator (FBO)

Service provider at an airport offering services like fueling and maintenance.

Runway Edge Lights

White lights outlining the edges of a runway for nighttime visibility.

Approach Lighting Systems (ALS)

Lighting arrays aiding aircraft alignment during the approach to a runway.

Weather Reporting Systems

Systems like METAR, TAF, and ATIS providing current weather and airport information.

Crosswind Component

Portion of wind blowing perpendicular to the runway, important for takeoff and landing performance.

Noise Abatement

Strategies to reduce aircraft noise impacts on surrounding communities.

FAA Part 150

Regulations focusing on airport noise compatibility planning.

Runway End Identifier Lights (REIL)

Flashing lights emphasizing the runway threshold to pilots.

Airport Beacon

Rotating beacon helping pilots identify an airport at night or in low visibility.
