scope:

1.1 This International Standard, constituting Part 2 of International Standard 7718, Aircraft - Passenger
doors interface requirements for connection of passenger boarding bridge, specifies the minimum dimensional
and unobstructed space requirements around future civil passenger transport aircraft upper deck passenger
doors when they are intended to be compatible with passenger boarding bridges planned in airports
worldwide.
1.2 This International Standard is not necessarily applicable to existing models of civil transport aircraft, or
future derivative models with the same fuselage. However, it is expected the design of such aircraft types may
be taken into account for design of passenger boarding bridges capable of upper deck servicing, in addition to
this International Standard.
1.3 It is not the intent of this International Standard to restrict in any way the basic design of any future
types of civil passenger transport aircraft. It aims, however, at clarifying for aircraft design engineers the
design characteristics which would make it difficult or impossible for a new type of aircraft to adequately
connect with airport passenger boarding bridges. Should basic aircraft design requirements impose on a
future model certain dimensional characteristics not complying with the present International Standard:
- either alternative methods of embarking/disembarking passengers will have to be implemented, such as
using the internal aircraft stairs, etc.;
- or upper deck passenger boarding bridges in the airports where such a new type of aircraft is to operate
will require some degree of modification/rework;
- or additional interface devices/equipment will be required in order to connect such a new type of aircraft
with existing upper deck passenger boarding bridges;
in either case resulting in increased aircraft handling constraints and operating cost.
