What type of data does the portable memory cartridge store?

The portable memory cartridge is designed to store digital information that can be utilized for loading and retrieval in the aircraft's systems. This includes not just flight data, but a variety of operational parameters and settings that the aircraft requires for efficient functioning.

The versatility of this memory cartridge allows for essential updates and changes to be made to the aircraft systems, ensuring that pilots have the most up-to-date information available. Such capability is crucial for maintaining optimal performance and safety during flight operations. While flight data, fuel data, and weather data are certainly critical components of an aircraft's functioning, they are typically part of the broader category of digital information that the portable memory cartridge can store and manage. Thus, the emphasis is on the capability of the cartridge to handle a wide array of digital information rather than being limited to a single aspect of flight operations.
