Airport Planning and Design
Published in Dušan Teodorović, The Routledge Handbook of Transportation, 2015
Payload weight and weight distribution on board the aircraft are critical in aircraft operations. The need to correctly and accurately measure and balance payload weight generates the need for passenger and baggage pre-processing. For that reason, passengers cannot simply move directly from their ground transportation vehicle to the aircraft. They need to first check in with the airline and hand in their baggage. The check-in process for passengers without baggage may be performed at a check-in counter, an automated self-service kiosk, or remotely via the Internet. Passengers with baggage to check in may also check in remotely but will need to stop at a baggage drop-in counter at the PTB before proceeding for boarding.

The forwarders in the trial were not identical and their net mass without tracks varied from 17,950 kg to 20,700 kg. Differences in forwarder design and track equipment resulted in estimated gross vehicle mass varying between 27,450 kg to 31,600 kg, the range being 4,150 kg or roughly 13 % of the average gross vehicle mass. Considering model results for Fomatec tracks with and without add-on track shoes mounted on the same forwarder, the add-on track shoes corresponding to a 2,000 kg mass difference may have had a remarkable effect on rut formation under the study conditions. When comparing track designs, it would be ideal to have identical vehicles with the same mass and same track width. Here, different vehicle designs were involved, so differences in mass, weight distribution and vehicle dynamics were inevitable.

From Fig. 7 and Table 4, it is observed that the distribution of axle weight is similar to that of the corresponding GVW, and a different distribution can be found for the axle weights of diverse vehicle types. For two-axle and four-axle vehicles, a typical bimodal distribution is found for all the axle weights, whereas a single-peak distribution for axle weight is observed for three-axle vehicles. Furthermore, by investigating the axle weight distribution of five- and six-axle vehicles, different distribution characteristics can be found for the first and other axles, which means that, for the first axle load, a typical single-peak distribution is observed, whereas a bimodal distribution is found for the second, third, fourth and fifth axles of five-axle vehicles, and the second, third, fourth, fifth and sixth axles of six-axle vehicles. By comparing the axle weight distribution for different types of vehicle, it can be concluded that the patterns of axle weight distribution can be influenced by vehicle type and axle number for five- and six-axle vehicles.
