(2) Use operating limitations if it provides the basis for an alternative to satisfying the criteria contained in this AC.
b. Operating Procedures.
(1) Assure the operating procedures in the A/RFM or A/RFM supplement are consistent with the criteria used to demonstrate the system.
(2) You should also document the application interoperability, sub-networks and performance designators identified in Table 5-1 and Table 5-2. For the following table, the data link type would be associated with the aircraft-allocated performance using the sub-network(s) in the far right column. The following examples illustrate common capabilities:
“The FAA has approved the aircraft data link system to the criteria contained in AC 20-140B for the following data link capabilities:
Data Link Type Aircraft-allocated Performance Sub-networks ATN B1 CPDLC at Initial Continental Performance using VDL M2 FANS 1/A+ CPDLC at RCP 240 using ADS-C at RSP 180 using VDL M0/A/2, SATCOM (Inmarsat), SATCOM (Iridium) FANS 1/A+ CPDLC at RCP 400 using ADS-C at RSP 180 using HFDL ACARS ATS None, using VDL M0/A/2, HFDL, SATCOM (Inmarsat), SATCOM (Iridium)
This design approval does not constitute operational authorization.”
(3) If the FAA approves variations to the criteria contained in this AC and these variations impact operational use of the data link system, the A/RFM should also include additional information that describes the operational impact. This may be accomplished by reference to other approved documents.
