Aircraft Systems

Question 1

What is the fixed tail wing surface of an airplane?

Answer 1

Stabilizer (vertical or horizontal)

Question 2

What is a servo tab?

Answer 2

Tab that moves opposite the control surface to relieve stick pressure

Question 3

What is an anti servo tab?

Answer 3

Moves with a stabilator to dampen control pressure

Question 4

Where is the aero tow cable connected?

Answer 4

On the nose

Question 5

Where is a ground launch cable attached?

Answer 5

On the center of gravity tow hook

Question 6

Name for back wheel

Answer 6

Breakaway wheel

Question 7

What is a P-lead wire?

Answer 7

A grounding wire to short the spark plug when ignition is off.

Question 8

What is the effect of a broken P-lead?

Answer 8

The engine can continue to run, or can start up when moving the propeller.

Question 9

What is a rotax engine?

Answer 9

An engine that uses an engine-driven generator.

Question 10

What are the two types of fuel induction?

Answer 10

Carburetor and fuel injection

Question 11

In what conditions is carburetor icing possible?

Answer 11

Between 20 to 70 degrees fahrenheit and high humidity or moisture.

Question 12

What is the first sign of carburetor icing?

Answer 12

A loss in power, as if the throttle were closed.

Question 13

What should you look for when you apply carburetor heat?

Answer 13

A momentary loss of RPM and roughness, then a rise in RPM.

Question 14

During what phases of flight should carburetor heat be used?

Answer 14

Any time the power is less than cruising flight.

Question 15

What should be done to fix engine detonation?

Answer 15

Cool the engine, either by enriching mixture, lowering power settings, or increasing airspeed.

Question 16

What is the sign of icing on a fuel injected engine?

Answer 16

Reduction in manifold pressure (RPMs are constant on a constant speed prop)

Question 17

How does a throttle work?

Answer 17

It restricts airflow, making the cylinders work harder to intake fuel/air mixture and slowing down.

Question 18

How to convert from C to F?

Answer 18

Multiply by 2 and add 30 to approximate.

Question 19

How do you avoid arcing from static electricity while fueling?

Answer 19

Always connect a ground wire. Never add fuel from a plastic container.

Question 20

What is an EGT?

Answer 20

Exhaust gas temperature gauge used for achieving ideal mixture

Question 21

How to convert from F to C?

Answer 21

Subtract 30 and divide by 2 to approximate.

Question 22

How to purge water from a fuel system with sumps and a fuel strainer?

Answer 22

Fuel strainer drain and fuel tank sumps.

Question 23

What change occurs to mixture when you apply carburetor heat?

Answer 23

The mixture is more rich (due to lower density air)

Question 24

How do carburetor engines take fuel in?

Answer 24

Pressure differential at the Venturi.

Question 25

What color is Avgas?

Answer 25

Blue

Question 26

What color is jet fuel?

Answer 26

Straw colored

Question 27

What will happen from use of low-grade fuel?

Answer 27

Detonation

Question 28

What is the best way to avoid condensation inside the fuel tanks?

Answer 28

Fill the tanks at night after each flight.

Question 29

Under what conditions can detonation or pre-ignition occur?

Answer 29

Too low fuel grade, high operating temperature, or excessive leaning of the engine

Question 30

What should be done in the event of pre-ignition or detonation?

Answer 30

Cool the engine, either by rich mixture, high airspeed, or lower power setting

Question 31

What is the function of engine oil?

Answer 31

To lubricate parts and carry heat away from the engine block.

Question 32

What are the two functions of fuel?

Answer 32

To power and cool the engine

Question 33

What should the avionics switch be set to before engine start?

Answer 33

Off

Question 34

In general, what should relationship between manifold pressure and RPMs should be avoided?

Answer 34

High manifold pressure with low RPMs

Question 35

In a contollable pitch propeller, how should you add power to a climb?

Answer 35

Advance the propeller control first, then the throttle second.

Question 36

Why should the propeller be moved to high RPMs before landing?

Answer 36

In case a go around is needed.
