This standard was written to define:

• An avionics interface between certified avionics equipment and non-certified EFBs

• A data communication protocol allowing access aircraft data parameters in both read and write mode (STAP)

• A data communication protocol providing a subscription-based service allowing access to aircraft data parameters in read mode (ADBP)

This standard does not define IP addressing rules or Dynamic Host Configuration Protocol (DHCP) existence. Network configuration details are the responsibility of the network system integrator.
