25
What is ADI and where is it found
Attuitude middle top. Attitude direction indicator
26
What is VSI and where is it found
Altitude. Vertical speed indication - top right
27
What is the basic T made up of
Airspeed, attitude, altitude and heading.
28
What is HSI and where is it
Horizontal situation indicator. Bottom middle
29
What does the ECAM or EICAS do
It is comprised of two displays in the middle. The top one shows the engine parameters. When a fault occurs then it comes up in detail in the bottom screen
30
What is an LCDS and what are the adv
Liquid crystal display. Lower and supplier power supply required. Produce less heat than CRT more robust Brightness set by pilot
31
What happens when there is total failure of EIS (electronic instrumental systems)
There is standby artificial horizon airspeed and altimeter
32
What are the buses that transmit that data called
ARNIC 429
33
What are the advantages EIS
Does not require all info during flight. Reducing clutter Variability and variety Coloured displays Fewer components needed Displays are interchangeable reducing redundancy
34
What’s a disadvantage of EIS
Bright sunlight. Could be difficult to read
35
What’s does the EADI or PRD display
Pitch and roll information Ground speed Flight director info Glide slope info Status
36
What does EHSI display
Magnetic heading Radio steering commands Way points airports and nav aids Distance to go
37
What can EHSI or ND be switched to
From rose which is a full compass to arc or sector which is more zoomed in to see for terrain weather etc
38
Which EIS has priority
EADI or PFD. Of display is lost then it moves onto EHSI or ND.
39
What was the earliest airspeed meter made from
Consisted of flexible bamboo strip or metal strip with a paddle on its end. As speed increase airflow pushed the paddle rearward.
40
What does the ADI provide
Attitude direction indicator provides positive and negative indications of altitude. It’s the master instrument.
41
What does a glass cockpit use now.
Cathode ray tubes (CRT) or liquid crystal displays (LCD)
42
What is an address
A name or number of info on the location that it’s needed to go to
43
What is a bit
