How long must terminating and intransit cargo be processed after aircraft arrival?

The correct answer is based on the established regulations concerning the processing times for terminating and intransit cargo after the arrival of an aircraft. Typically, these regulations require that such cargo be processed within an 18-hour window. This timeframe is dictated by operational efficiency and logistical requirements to ensure that cargo reaches its final destinations without unnecessary delay, allowing for proper handling, inspection, and forwarding.

The 18-hour processing limit helps maintain the flow of supply chain logistics within the Air Force and ensures that cargo meets mission readiness. By adhering to this timeframe, the Air Force can optimize resource allocation and ensure that air freight operations remain efficient and effective.

The other options represent different timeframes that do not align with the regulatory standard, which underscores the importance of understanding these specific guidelines in air freight operations.
