compatibility assessment is provided by the
Aircraft Classification Number/Pavement
Classification Number (ACN/PCN) system. An
aircraft having an ACN equal to or less than the
pavement’s PCN can use the pavement safely, as
long as it complies with any restrictions on the
tyre pressures used. Figures 11.18 and 11.19
show typical rigid pavement data (see also
Section 11.2) whilst Figure 11.20 shows data for
flexible pavement use.
Airside and landside services
The main airside and landside services consid­
ered at the airport design stage are outlined in
Table 11.2.

11.1.5 Airport design types
The design of an airport depends principally on
the passenger volumes to be served and the
type of passenger involved. Some airports have
a very high percentage of passengers who are
transiting the airport rather than treating it as
their final destination, e.g. Chicago O’Hare
