Lesson 1

Question 1

is vital to maintain the safe and efficient operation of the aeroplane engines and their associated systems. It varies according to the type of engines fitted (e.g. piston, turboprop, or gas turbine), and in many cases the individual instruments are identical.

Answer 1

Instrumentation

Question 2

A heat engine that uses one or more reciprocating pistons to convert pressure into a rotating motion.

Answer 2

PISTON ENGINES

Question 3

It uses a piston that moves up and down inside the cylinder.

Answer 3

PISTON ENGINES

Question 4

This is a measure of how much work is being done by the engine and is measured in revolutions per minute (rpm).

Answer 4

Engine Speed or (TACHOMETER)

Question 5

This is a measure of the engine power of a supercharged engine (absolute pressure).

Answer 5

Induction Manifold Pressure, or Boost Pressure (MAP)

Question 6

is usually given in inches of mercury (in Hg), and boost is normally measured in pounds per square inch (psi).

Answer 6

MAP or Manifold Air Pressure

Question 7

more on suction

Answer 7

BOOST PRESSURE GAUGE

Question 8

inside pressure

Answer 8

MAP or Manifold Air Pressure

Question 9

Super charged engine is designed for an aircraft that flies up to [?] feet above sea level.

Answer 9

10, 000 feet

Question 10

Acts on the output shaft of the engine and is proportional to the horsepower developed. It is occasionally used to provide information for power control.

Answer 10

Torque or Turning Moment

Question 11

means the rotation of the shaft of the engine.

Answer 11

TORQUE

Question 12

Helps in monitoring the condition of the reduction gears (set of gears that control the rotation of the propeller and the crankshaft).

Answer 12

TORQUE

Question 13

This temperature is important because excessive temperatures can cause engine damage.

Answer 13

Cylinder Head Temperature

Question 14

The temperature is measured in degrees Celsius.(°C).

Answer 14

Cylinder Head Temperature

Question 15

When the pointer exceeds to the [?], it means the engine has a malfunction that causes overheating and can damage other components.

Answer 15

red line

Question 16

Cylinder Head Temperature uses a [?] sensor then sends the signal to the instrument.

Answer 16

thermocouple

Question 17

Ensures adequate lubrication of the engine. In pressure terms it may be HIGH or LOW, whereas the temperature is usually in degrees Celsius (°C).

Answer 17

Lubricating Oil Pressure and Temperature

Question 18

is very important in engine operation for its purpose (cooling, lubrication and cleaning).

Answer 18

OIL

Question 19

Purpose of Oil

Answer 19

cooling
lubrication
cleaning

Question 20

When the temperature gauge is too high and the pressure is low it indicates [?] of the engine.

Answer 20

OVERHEATING

Question 21

Provides a measure of the economy of the engine, and is measured in pounds, kilograms or gallons/hour.

Answer 21

Fuel Flow

Question 22

indicates when there is a blockage or leakage on the fuel lines going to the engine.

Answer 22

FUEL FLOW

Question 23

When the fuel flow shows a higher indication than the normal amount it may show that there is a [?].

Answer 23

leakage

Question 24

Then when it drops it means there is something that [?] the fuel to flow on the engine.

Answer 24

blocking

Question 25

Shows if the aircraft alternator is charging during normal operation. If continuous discharge is shown during flight, it is prudent to land as soon as possible as it would suggest that the battery will shortly become too depleted to operate normal aircraft.

Answer 25

Ammeter

Question 26

Monitors the condition of the vacuum system which is driven from the engine.

Answer 26

Vacuum Gauge

Question 27

The [?] drives the gyros for the artificial horizon and heading indicator instruments.

Answer 27

vacuum system
