What is an advantage of Electronic Instrument Systems (EIS)?
Each display has its own dedicated information.
Monitors are interchangeable and information can be transferred between displays.
The inputs are via dedicated wiring to each monitor individually and therefore make fault diagnosis easier.
In the event of a total Electronic Instrument System (EIS) failure, what backup information is available to the pilot?
Standby Autopilot and Compass System
Standby Monochrome-Screen Electronic Instrument System
Standby Artificial Horizon, Airspeed Indicator and Altimeter
A Wing and a Prayer
What type of information is displayed when the EHSI has ARC mode selected besides system generated flight plan?
Both GPWS and TCAS
Weather radar or GPWS or TCAS
Both TCAS and Weather Radar
On the Electronic Horizontal Situation Indicator (EHSI), which mode would typically show Flight Plan along with either Weather Radar, GPWS or TCAS information?
ROSE mode
ARC or SECTOR mode
VSTOL mode
What is not an advantage of LCD over CRT displays?
More Robust
Dissipate more heat
Need less power
In a typical glass cockpit, the Electronic Instrument System (EIS) is shown on many identical Liquid Crystal Displays (LCDs)?

Why have analogue instruments been replaced by digital instrument systems?
Digital systems are more clearly visible and can filter information.
Analogue instruments are too slow.
They look better.
Which are the advantages of digital displays over analogue displays?
They are easier to read in bright sunlight.
Important information can be accentuated and displayed in various colours.
Digital displays have better illumination than analogue displays.
Which of the following is correct regarding the Electronic Flight Instrument System (EFIS) display units?
They use binary and hexadecimal data.
They are different types.
They are the same type.
Which two methods are used for brightness control of Engine Information System (EIS) monitors?
Control knob and photocells
Thermocouples and control knobs
Filters and control knobs
In normal operation, what display will show normal aircraft parameters?
The Electronic Centralised Aircraft Monitoring System (ECAM).
The Aircraft Condition Monitoring System (ACMS).
The Central Maintenance System (CMS).
If an Electronic Horizontal Situation Indicator (EHSI) or Electronic Attitude Direction Indicator (EADI) display fails, what will be shown on the remaining display?
The remaining display will alternate between both displays
A composite mode showing combined elements of both displays
All information is shown but reduced in size
What is the primary function of the Electronic Flight Instrument System (EFIS)?
To provide digital readouts of aircraft parameters.
To control the aircraft's autopilot system.
To manage the aircraft's fuel system.
What is a characteristic advantage of Electronic Instrument Systems (EIS) over analogue instruments?
Increased clutter and pilot workload
Limited variability and variety
Displaying only necessary information
Use of various display types
What is the primary function of Multi-function Control Display Units (MCDU) in aircraft instrumentation?
Displaying navigation information
Acting as an interface to the flight management system
Providing backup instruments in case of failure
Controlling the brightness of displays
A typical EFIS system comprises a
Primary Flight Display (PFD) & Electronic Attitude Direction Indicator (EADI)
Engine Indicating and Crew Alerting System (EICAS)
Electronic Centralized Aircraft Monitor (ECAM)
Electronic Horizontal Situation Indicator (EHSI) (Navigation Display)
Within the cockpit of an aircraft, what does the acronym EIS stand for?
