Hello, I am a student currently studying avionic engineering at college, we are currently do some work on EFIS and aircraft data buses , I am finding it difficult to find out information to answer the questions below as the way the questions are set means that they are brief and vague, any help/information you could give me would be greatly appreciated;
1) If a single item of information is missing from all the electronic flight deck display screens on which it is normally displayed, then the most likely cause would be loss of signal from the :-
a) Display controller or symbol generator
b) Display controller or the input sensor
c) Symbol generator or input sensor
2) The Electronic flight instrument system consists of :-
a) Air data computer, airspeed indicator, altimeter and vertical speed indicators
b) Mode select panel, stroke and raster generators displays, display controllers and main processor
c) Heading situation indicator, attitude director indicators and symbol generators
3) In an ARINC 629 data transmission system, line replaceable units :-
a) May be connected to more than one data bus and can transmit and receive data on each individual data bus
b) Must transmit on one data bus and receive on a separate data bus
c) Can only transmit and receive on one data bus
4) The BITE test used for checking the correct alignment of sensors and actuators is the :-
a) System performance test
b) Line replaceable unit power-up self test
c) Line replaceable verification test
Thankyou for your help
