問題詳情

For most modern airports, the major design problem is scale – how to allow adequate space on the ground for maneuvering wide-body jets while permitting convenient and rapid movement of passengers departing, arriving or transferring from one flight to another.Most designs for airport terminals take one of four approaches. In the linear plan, the building may be straight or curved. The passengers board aircraft parked next to the terminal. This plan works well for small airports that need to provide boarding areas for only a few aircraft at a time.In the pier plan, narrow corridors or piers extend from a central building. This plan allows many aircraft to park next to the building. However, it creates long walking distances for passengers.In the satellite plan, passengers board aircraft from small terminals that are separated from main terminals. Passengers reach the satellites by way of shuttle trains or underground passageways that have moving sidewalks.The transporter plan employs some system of transport to move passengers from the terminal building to the aircraft. If buses are used, the passengers must climb a flight of stairs to board the aircraft. If mobile lounges are used, they can link up directly with the aircraft and protect passengers from the weather.
48. It can be inferred that scale would not pose a major design problem at airports if
(A) airports were much larger.
(B) other efficient forms of transportation were available.
(C) aircraft did not need so much space to maneuver on the ground.
(D) the satellite plan made use of mobile lounges.
