benefits of Aircraft digital data system
allows the added the added benefits while keeping weight and maintenace cost down
what two diferent data rates are used ?
- LS (Low speed)-12.5 Kbits/sec(10-14.5)
- HS(high speed) 100 Kbits/sec
An ARNIC 429 signal is of a format know as ?
bipolar return to zero
bipolar means that the polarity of tghe signal actually reverses for 1 to 0
This system advises flight crew of something that needs their attention
master caution
This can be useful in following current paths to see what operates and when.
wiring diagram
This annunciation has a higher priority over this annunciation
warning caution
This device will give a Digital High output only when the inputs are not the same
XOR GATE
Decimal 25 is converted to 19 in which numbering system
HEXADECIMAL
Which Data buss is uni-directional
ARNIC 429
The use of this improves redundancy, Improves accuracy and safety
DATA BUS
This device needs both inputs to be the same, but its output is opposite of the inputs
NAND GATE
This is used for data error checking in a data bus word
PARITY BIT
In the ARINC429 data bus, one transmitter can send data to this many receivers.
