Airport Diagram

Airport diagrams are pictorial maps of the airport environment to gain and maintain situational awareness in the terminal area.

Introduction to Airport Diagram

  • Airport diagrams are specifically designed to assist in the movement of ground traffic at locations with complex runway/taxiway configurations and provide information for updating computer based navigation systems (INS) aboard aircraft
  • Runway dimensions, elevations, and gradient (if greater than 0.3° up or down)
  • Airport diagram scales are variable
  • Runway heading to the nearest tenth of a degree
  • Dimensions of runway overruns
  • Runway identification number
  • Location of arresting gear, barriers, and displaced thresholds
  • Position and identification of taxiways, ramps and parking areas
  • Type of runway surface
  • Closed runways/taxiways
  • Location/identification of buildings, control tower, airport beacon, and other structures
  • True/magnetic north orientation, date, and annual rate of change - true/magnetic north orientation may vary from diagram to diagram, i.e., north may not be at the top of the page
  • Location/elevation of obstructions
  • Geographical coordinate grid - Coordinate values are shown in 1 or 1/2 minute increments. They are further broken down into 5 second ticks, within each 1-minute increments
  • Runway weight-bearing capacity
  • Airport diagrams are not intended to be used for approach and landing or departure operations
  • Reinforce your understanding of Airport Diagram by completing the knowledge quiz and interactive scenario, comparing your performance with the applicable Airman Certification Standards, and reviewing the topic summary before moving on.

Airport Diagram Key Highlights

  • Airport diagrams provide pilots with detailed airport layout information for taxi, runway, ramp, and surface movement operations.
  • Diagrams identify runways, taxiways, aprons, terminals, hotspots, hold-short lines, and other important airport surface features.
  • Pilots use airport diagrams during preflight planning, taxi briefings, arrivals, departures, and ground movement operations.
  • Hot spots on airport diagrams identify areas with increased risk of runway incursions or surface movement confusion.
  • Airport diagrams help pilots comply with taxi instructions, runway assignments, and air traffic control clearances.
  • Runway dimensions, lighting information, elevation data, and communication frequencies may be included on airport diagrams.
  • Pilots should review airport diagrams before operating at unfamiliar or complex airports to reduce workload and navigation errors.
  • Electronic Flight Bags (EFBs) and moving map displays can improve airport surface situational awareness.
  • Outdated or misread airport diagrams can contribute to taxi errors, wrong-runway events, and runway incursions.
  • Understanding airport diagrams improves ground navigation, airport safety, and overall operational awareness.

Airport Surface Hot-spots

  • An airport surface hot spot is a location on an airport movement area with a history or potential risk of collision or runway incursion, where heightened attention by pilots and drivers is necessary.
    • It is a runway-safety problem area that presents increased risk during surface operations.
  • A hot spot is typically a complex or confusing taxiway/taxiway or taxiway/runway intersection.
  • Contributing factors include airport layout, traffic flow, airport markings, signage and lighting, situational awareness, and training.
  • Circles or ellipses identify ground-movement hot spots.
    • These may involve hold-short line infractions, approach-hold issues, complex taxiways, movement/nonmovement boundaries, tower line-of-sight problems, or marking and signage issues.
  • Cylinders identify wrong-surface hot spots.
    • These mark locations where aircraft have inadvertently attempted to, or actually did, depart from or land on the wrong surface.
  • Labels such as HS 1, HS 2, and HS 3 connect each diagram location to a brief description in the Chart Supplement U.S..
    • Read the description on the hot spot table to understand why the location is highlighted.
  • Hot spots remain charted until the increased risk has been reduced or eliminated.
  • The FAA’s From the Flight Deck videos provide additional airport-specific coverage of hot spots and surface-safety concerns.
  • Brief the route: Before taxiing, identify hot spots along the assigned route, the specific hazard at each, and applicable holding positions.
  • Check current conditions: Review current airport information, notices, and closures; construction or temporary changes may affect the route.
  • Reduce distractions: Keep the diagram available, maintain an outside scan, and postpone nonessential tasks while navigating the hot spot.
  • Stop if uncertain: On a taxiway, stop and request clarification from air traffic control if unsure of your position or clearance. Obtain an explicit runway-crossing clearance when operating under tower control.

HS 1 — Taxiway F versus Taxiway G

FAA description: “Acft ldg Rwy 05 and instructed to exit on Twy A with a left turn onto Twy F to the east ramp, sometimes turn left onto Twy G by mistake.”

In plain language: after landing on Runway 05 and exiting onto Taxiway A, a left turn intended for Taxiway F toward the east ramp can be confused with Taxiway G.

HS 2 — Runway 02–20 holding position

FAA description: “Rwy holding position marking Rwy 02–20 located at the intersection of Twy E and the ramp.”

In plain language: the holding position for Runway 02–20 is at the Taxiway E/ramp intersection. Locate the marking before moving toward the runway.

HS 3 — Crossing Runway 05–23

FAA description: “Acft ldg Rwy 02 that are instructed to exit left on Twy A sometimes cross Rwy 05–23 wo clnc.”

In plain language: aircraft landing on Runway 02 and exiting left onto Taxiway A may cross Runway 05–23 without clearance. Identify the crossing while planning the exit.

Locating Airport Diagrams

  • Current FAA airport diagrams are available from official sources:
    • Full-page airport diagrams are published in the Terminal Procedures Publication and are available as individual Airport Diagram charts through the FAA's digital Terminal Procedures Publication search.
    • Selected airport diagrams are also published in the Chart Supplement U.S.
    • Pilots should verify that the diagram is current and review applicable Notices to Airmen before use.
