Taxiway

Definition

A taxiway is a designated path on an aerodrome that connects runways with aprons, hangars, stands, and other operational areas. Taxiways are used by aircraft before takeoff and after landing, allowing them to move safely and efficiently across the ground under their own power.

Purpose

  • Enable safe and orderly ground movement of aircraft
  • Connect aircraft to runways, terminals, and parking areas
  • Support efficient traffic flow during busy operations
  • Minimize runway occupancy time and delays

Taxiway Identification

  • Taxiways are identified by letters (A–Z) and sometimes letter-number combinations (e.g., A1, B2).
  • Standard: Single capital letters (e.g., A, B, C)
  • Sub-segments: Combination of letter + number (e.g., D1, E2)
  • Markings: Solid yellow centerlines, optionally with edge markings
  • Signs: Black letters on a yellow background (directional), or yellow letters on a black background (current position)

Types of Taxiways

TypePurpose
Parallel taxiwayRuns parallel to the runway for efficiency
Exit taxiwayLeads aircraft off the runway after landing
High-speed exitAngled taxiway allowing faster runway vacating
Cross taxiwayConnects multiple apron/runway areas
Remote stand taxiwayConnects to remote parking or GAC apron

ATC and Taxi Instructions

All taxi movements at controlled airports require explicit ATC clearance. Taxi instructions include:

  • Route via designated taxiways
  • Clearance to cross or hold short of runways
  • Destination (e.g., holding point, stand, GAC)

Phraseology Examples

  • “Taxi to holding point runway 09 via Taxiways Alpha and Charlie”
  • “Taxi to stand 23 via Bravo and Apron North”
  • “Hold short of runway 27 at Taxiway D1”
  • “Cross runway 08, continue via Echo”

Holding Points and Intersections

  • Taxiways intersect with runways and other taxiways at marked positions
  • Holding points are where aircraft stop before entering runways
  • Intersections are managed via signage and controller instructions
  • Stop bars may be used at critical points to prevent runway incursions

Pilot Responsibilities

  • ✅ Follow taxi route as assigned by ATC
  • ✅ Use airport charts to verify route and position
  • ✅ Read back all runway crossings and hold short instructions
  • ✅ Turn on taxi lights and beacon during movement
  • ❌ Never enter a runway without explicit clearance

Progressive Taxi

ATC may offer or the pilot may request progressive taxi instructions. Useful for:

  • Unfamiliar pilots
  • Complex layouts
  • Low visibility

Example:
“Taxi straight ahead, then turn right at the next intersection, I will call further.”

Taxiway Safety Tips

  • Confirm runway crossing instructions verbally and visually
  • Always use the correct taxiway designator — avoid “winging it”
  • Stay alert for ground traffic: vehicles, pushbacks, other aircraft
