Boeing 747 with respect to mass and dimensions are not considered relevant to the
threat, the engines are interesting for a separate examination due to their size and
dimensions.
13.3.1.3 Airbus A380
The Airbus A380 is currently the largest civilian commercial aircraft that has
entered serial production. It is a four-engined wide-body aircraft with two contin-
uous decks with a capacity for approx. 525 passengers and is in use since 2007.
Approximately 320 aircraft have been commissioned to date. The length of the
aircraft is 72.30 m and the wingspan 79.80 m. It has an elliptical cross section of the
fuselage of 7.15 m in width and 8.40 m in height. The maximum take-off weight is
close to 560 t including 320,000 l (
256 t) of kerosene.
This aircraft model was not considered in detail in the examinations directly
after September 11, 2001 because the aircraft was not in use and no specific details
were available neither from the manufacturer nor from the airline companies at the
time. The first examples of this aircraft have only been in use since 2007 (Fig.

13.3.1.4 Airbus A340
The aircraft A340, built by Airbus, has a capacity of 260-340 passengers. The
length of the aircraft is between 60 and 64 m, the wingspan approx. 60 m and the
maximum take-off weight 270 t including 120 t of kerosene. A larger model with a
fuselage that is elongated by 25 ribs has a capacity of 420 passengers. The
maximum take-off weight of this larger variant increases to approx. 380 t, of
which approx. 150 t are kerosene (Fig.
13.6
).
The A340-600 corresponds roughly to the Boeing 747 with respect to total
weight and its dimensions. The greater wing angle and the slightly lower weight
result in a higher mass concentration in the middle of the aircraft where the wings
