What is the characteristic of the CDF in terms of amenities?

The characteristic of the CDF, or Cargo Distribution Facility, relating to amenities is best captured by the presence of flood lights and yellow trucks parked. This reflects the nature of the facility, which is designed to support cargo operations. The use of flood lights indicates operations that may occur around the clock, ensuring that cargo handling can take place during both day and night. The yellow trucks parked signify the vehicles frequently used for transporting cargo, which are typically painted in bright colors for visibility and safety purposes within the airside environment.

The other aspects mentioned in the other choices do not accurately represent the primary amenities of the CDF. For example, while it may possess various attributes supporting logistics, being primarily a cargo facility centers the focus on operational capabilities rather than passenger amenities. Additionally, although it may have maintenance facilities, these are not the defining amenities of such a facility compared to the visibility and operational readiness suggested by the presence of flood lights and yellow trucks. A passenger terminal is characteristic of passenger processing facilities rather than cargo distribution, reinforcing that the amenities in question are component-specific to cargo operations.
