28VDC
34
Deterministic performance of an Ethernet system used for an IMA system network is provided
By use of virtual links signing the Ethernet network system
35
Differences between CPIOMs are determined by
The type of system of the computer interfaces with
36
How does AFDX transmit data
Through ADCN
37
In an atomic 653 certified IMA system
It is permitted to add software such as health monitoring or mission support functions within new ARINC 653 partitions that may not be certified to the same level as flight critical function a
38
In an IMA system software is upgraded
Without the need to upgrade the hardware
39
In the event of a single AFDX switch loss
There will be no aircraft systems effect due to the redundant duplication of networks in the ADCN
40
In the event of multiple AFDX switch losses on both of the ADCN networks
There is a functional effect on the aircraft systems and this will trigger the master caution and is a no go failure
41
In the event of multiple AFDX switch losses in one of the ADCN networks
There will be no function effect on systems but this a no go failure
42
