Editorial Aerodrome Deep Dive: London Heathrow Airport (LHR)

Curated Aerodrome Profile

London Heathrow is internationally recognized as the world's most intensively utilized two-runway system. Operating within strict noise quotas and a dense urban airspace shared with five other commercial London airports, LHR relies on Time-Based Separation (TBS) on final approach to maintain throughput in high headwind conditions. Both paved runways exceed 12,000 ft, ensuring unrestricted all-weather heavy widebody recovery under UK Category IIIb low-visibility procedures.

Runway Layout & Magnetic Alignments
Dual parallel east-west runways: 09L/27R (12,802 ft / 3,902 m) and 09R/27L (12,008 ft / 3,660 m).
Expansion Milestones & Predecessor Facilities
Commissioned in 1946 on the site of Great West Aerodrome. The airport expanded through five passenger terminals, culminating in Terminal 5 in 2008 and Terminal 2 (The Queen's Terminal) in 2014, with perpetual planning debate surrounding a proposed third northwest runway.
Regional Differentiation & Cluster Role
Functions at 99% slot capacity as London's premier legacy and transatlantic hub, contrasting with single-runway point-to-point Gatwick (LGW) and low-cost gateway Stansted (STN).
Data Nuances & Operational Quirks
Implements runway alternation at 15:00 daily during westerly operations, switching landing and departure duties between 27L and 27R to grant noise respite to West London communities.
