This airframe is configured as a main-deck freighter with a pallet system using powered rollers and has no passenger cabin; the flight deck accommodates 2 flight crew. Typical missions for this configuration are long-range cargo operations within the 747-400 freighter performance envelope, utilizing a cruise speed of 506 kts and a maximum operating ceiling of 45,000 ft. The aircraft is operated and maintained under the auspices of its corporate owner in Louisville, KY, with maintenance considerations driven by freighter-specific systems such as the powered roller pallet handling system and the quad-engine CF6-80C2B1F propulsion suite. Avionics fit and specific navigation/communication suites are not published in the supplied data.

The Boeing 747-44AF(SCD) variant sits in the large, long-range freighter niche, offering substantial main-deck volume and transcontinental to intercontinental range of 4,450 nm. Its four CF6-80C2B1F engines deliver 57,160 lbf of thrust apiece, supporting robust payload capability and cruise performance. Competing aircraft in the heavy freighter segment include other 747 derivatives and large twinjets converted for cargo, with operator demand driven by cargo volume and network needs. Maintenance and resale considerations for this airframe reflect its age since the 2009 build year, the complexity of four-engine operations, and freighter conversion equipment such as the powered roller pallet system.
