M5.1 Electronic Instrument Systems Cat B1 & B2

Why have analogue instruments been replaced by digital instrument systems?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 happens when the Engine Information System (EIS) monitor's brightness control fails?

• The monitor will revert to a default brightness setting.

• The monitor will become too bright to read.

• The monitor will become too dim to read.

In the early stages of aviation, how did pilots monitor their airspeed?

• Using modern Air Speed Indicators

• By relying solely on cockpit instruments

• By observing the movement of a flexible bamboo strip or metal spring

• With the help of radar systems

What technological advancement led to the decrease in the number and variety of instruments on cockpit panels?

• Mechanical back-ups
