What do IMA stand for and what does it replace
Integrated modular avionics
Several LRUS
What positives do IMA’s have
Reduced weight and size
Lower power consumption
Easier mods
Reduced reoccurring costs
What are airbus and Boeings acronyms for aircraft date network (ADN)
Airbus- avionics data communications network
Boeing- common data network
What’s the bandwidth allocation gap
A mechanism that is used for controlling the amount of info a LRM or LRU can transmit
What’s the cyclic redundancy check
Checks for errors in data storage or transmission
What are IMA’s known as for Boeing and Airbus
Boeing- GPM
Airbus- CPIOM
How many LRM’s ans software functions are hosted in the CPIOMS
30 LRM
22 software functions
For extra reliability what’s the ADFX channels requires to be
Dual
Added info not in notes
So two sources of information so u know accurate results are coming through
What do Boeing refer to there IMA systems as
Whats do airbus refer to there avionics systems as
Boeing- CCS (common core system)
Airbus- ADFX (avionics full duplex switched Ethernet)
What does the CCS do
Platform that allows computing, communication and I/O services
What are advantages of using RDC’s (remote data controllers)
Reduction in wiring
Reduce amount of devices connected to CDN
reduction in spare parts needed in inventory
How many RDC are there in the CCS
21
What are GPM’s designed to be
Fail passive
What’s important to remember about I/O modules
Fully interchangeable
I DIDNT KNOW HOW TO FUCKING WORD IT BUT IT WAS IN BOLD
