The introduction of the A380 necessitate airports to make allowance for this new heavy
type of aircraft in their maintenance, rehabilitation and reconstruction programs during the
coming years. A design method incorporating these types of NLA aircraft does not exist yet,
which has led to the use of a mechanistic analytical design based on the APSDS approach. For a
relative comparison the computer based LEDFAA method has been used, although this method
has been introduced only to cope with the tridem landing gears of the B777. On the one hand the
design principles of LEDFAA have been followed, on the other hand the APSDS procedures
have been followed as closely as possible.
