Explanation / Answer

5. JIAWG is a Joint Integrated Avionics working group.It is based on the avionic system which uses a modular technology. Avioinic systems are the electronic systems used in the aircraft, in which JIAWG is one of the group implementing the system with a modular technology.
HSDB is the high speed data bus which is used in the JIAWG to increase the speed of the avionics, i.e the speed of navigation.
6.In the advanced JIAWG architecture the bus is updated as PI- backplane bus such that the computer systems used in the architecture will get the ability of exchanging and making use of their information from the neighbouring systems.
7. TRUE.
As we know the JIAWG architecture which has SAE AS4710 has a transfer rate of 50 Mega bytes per second only. Hence it has failed to acheive commercial or military acceptance.
8.
JIAWG architecture works with a normal approach as stated above but the avionics architecture implemented on F-22 module uses the integrated approach. Hybrid circuits are implemented in the F-22 moduled to reduce the number of pin outs from the modules, which increases the efficiency of the avionic system.
