Qualification of Percon® 24, a New High-Strength Conductor Alloy to AS29606

2021-03-23
CURRENT
AIR7929
This SAE Aerospace Information Report (AIR) is limited to information about evaluation of a new cadmium-free high-strength copper alloy. The testing described in this AIR was conducted prior to the publication of AS6324 and is intended to provide information regarding evaluation of this new copper alloy. It is recognized that a simple specification such as AS29606 can not cover all possible requirements for performance in every field application. To address this basic issue, the introduction of a new, but similar to already field proven, component requires comparative testing to verify the new component will perform at the same or above level as the already approved component in a broader set of relevant tests.

DATALINK GROUND SYSTEMS STANDARD AND INTERFACE SPECIFICATION (DGSS/IS)

2020-07-31
CURRENT
ARINC620-10
ARINC Specification 620 defines the interfaces between the Datalink Service Provider (DSP) and the aircraft, other ground-based datalink services, and users. The datalink ground system standard definition supports traditional ACARS and AOA protocols, as well as Media Independent Aircraft Messaging (MIAM) as defined by ARINC Specification 841. MIAM messages can be much larger than ACARS messages (5 MB versus 3.3 kB per message). Supplement 10 improves Controller-Pilot Data Link Communications (CPDLC) by defining a “Deliver By (DB)” period that allows the DSP, that originated the message, to intercept and discard the message if it is not delivered by the specified time. Supplement 10 also adds a Media Advisory code for ACARS over IP (AoIP) indicating that an ACARS non Safety Services messages is being transferred over IP links. New Reason Codes are assigned for un-transmittable or undeliverable messages. ACARS Character set clarifications are also provided in Supplement 10.
