Fuselage Cross-Sections vs. ICAO Aerodrome Reference Codes
Comparing 2 standards across 11 specifications. 11 key differences identified.
Comparing:
Fuselage Cross-Sections
ICAO Aerodrome Reference Codes
Commercial airliner fuselages are engineered around standardized interior cabin diameters that dictate cross-aisle seat arrangements: Single-Aisle Narrow-Body (3-3 seating, 3.5–3.7 m cabin) vs. Twin-Aisle Wide-Body (2-4-2, 3-3-3, or 3-4-3 seating, 5.3–6.5 m cabin).
The ICAO Aerodrome Reference Code classifies commercial aircraft into Code Letters A through F based on wingspan and outer main gear wheel span (OMGWS) to dictate airport runway width, taxiway clearances, and gate parking dimensions.
