1) Flight instruments normally conform to a standard layout to Report

Ensure consistency of information between aircraft types

Simplify maintenance and fault diagnosis

Comply with Civil Aviation regulations

2) Instruments associated with guiding the aircraft from one point on the earth to another are classified as Report

navigation instruments.

flight instruments.

aircraft attitude indicators

3) "Flight Instruments" are classified as those instruments that Report

indicate the altitude of the aircraft

are connected to the Pitot Static system.

provide the pilot with a picture of the aircraft's flight condition.

4) Aircraft instruments generally use the following principles to measure and display information:- Report

Temperature, Pressure, Acceleration, Magnetism, Gyroscopic.

Altitude, Attitude, Heading.

Airspeed, Distance, Groundspeed, Bearing.

5) Straight scale instruments are usually chosen for their:- Report

accuracy.

space saving.

ability to display large ranges of information such as altitude.

6) The green arc on an aircraft temperature gauge indicates:- Report

The instrument is not calibrated.

The desirable temperature range.

A low, unsafe temperature range.

7) When installing an instrument in an aircraft, responsibility for ensuring it is properly marked lies with the Report

pilot

instrument installer.

instrument manufacturer.

8) Which of the following instruments could be described as a High-Range or Long-Scale instrument? Report

EGT (Engine Exhaust Gas Temperature) gauge.

Attitude Indicater

Altimeter.

9) An aircraft instrument panel is electrically bonded to the aircraft structure to Report

Act as a restraint strap.

Provide a positive power supply for the panel lighting

Provide current return paths.

10) Differences between instrument readings taken as an applied parameter is increasing and those taken when the same parameter is decreasing, is generally due to Report

hysteresis

instrument "lag"

friction

11) Annunciators:- Report

Are always colored Red.

May annunciate a certain condition or mode of operation of a system.

Are always located on a central warning panel that the pilot can easily see.

12) The "tolerance" of an aircraft instrument is a measure of Report

how well it can tolerate different levels of vibration.

the level of inaccuracy allowed before it needs to be recalibrated

the accuracy of the readings shown on the instrument face.

13) The aircraft symbol on a Artificial Horizon is : Report

Is connected to the outer Gimbal ring of the gyro.

Fixed to the instrument case.

Turns as the aircraft banks left and right.

14) The Graduation Marks on an Instrument refer to:- Report

The marks provided to assist in disassembling the instrument.

The marks on the instrument scale which enable the instrument to display a value for the parameter being monitored.

Amount of possible positions the instrument pointer may stop at.

15) Which of the following would be considered a sensitive instrument? Report

Hydraulic pressure gauge.

Altimeter.

Brake pressure gauge.

16) The term "Servo Instruments" refers to those instruments which:- Report

Have more than one scale.

Are driven by electrical signals from the Air Data Computer.

Which show the position of the aircraft servos.

17) What advantage do ratiometer measuring circuits have compared with Wheatstone Bridge circuits? Report

If the supply voltage varies this will be detected by the instrument.

If the supply voltage varies there will be no effect on the instrument reading.

If there are any faulty, dirty or loose connections in the Ratiometer circuit this will have no effect on the instrument reading.

18) What category of instrument is an aircraft Attitude Indicator display? Report

Symbolic

Straight Scale

Circular or clock scale

19) Shock mountings on aircraft instrument panels are designed to absorb vibration at Report

all frequencies

low frequencies and low amplitude

high frequencies and high amplitude

20) The number and size of the marks on instrument dials are designed to:- Report

provide a quick accurate interpretation of the readings.

ensure that the entire range of the instrument can be displayed on the instrument dial.

reduce instrument zero error.
