Based on its wingspan, the U.S. FAA classifies the A380 as a Design Group VI aircraft, and originally required a width of 60 m (200 ft) for runways and 30 m (100 ft) for taxiways, compared with 45 m (150 ft) and 23 m (75 ft) for Design Group V aircraft such as the Boeing 747, but recently the FAA has
relaxed the runway width classification for the A380 to 45m.
Airbus claimed that the A380 could safely operate on Group V runways and taxiways, without the need for widening. Both the FAA and EASA agreed that the A380 can operate on Group V runways and taxiways. The ICAO is still disputing this assertion.
When operating on Group V infrastructure, the FAA originally considered limiting the taxi speed of the A380 to 25 km/h (15 mph), but has since issued waivers related to the speed restriction and some of the proposed runway widening requirements.
Takze 45m neni problem.. a jak bylo receno, kdyz pristava An225 tak proc ne A380
