Airplane Systems

Question 1

What are the 4 main control surfaces?

Answer 1

Elevators
Ailerons
Rudder
Trim Tabs

Question 2

What is the landing gear on your aircraft?

Answer 2

Tricycle gear with a movable nose-wheel

Question 3

What is the braking system on your aircraft?

Answer 3

A hydraulic line connects each brake to a master cylinder on each pilot’s rudder pedals

Question 4

How is steering accomplished on the ground?

Answer 4

Simple mechanical linkage connects the rudder pedals to the nose wheel

Question 5

Describe the engine on your aircraft?

Answer 5

Horizontally opposed
Four cylinder
Overhead valve
Air cooled
Carbureted engine
Lycoming 160 HP

Question 6

What are the 4 engine strokes?

Answer 6

Intake
Compression
Power
Exhaust

Question 7

What does the carburetor do?

Answer 7

Mixes the fuel and air

Question 8

How does carb. heat work?

Answer 8

A heat valve allows unfiltered heated air from a shroud around the exhaust to be directed to the induction air manifold prior to the carburetor.

Question 9

What changes occur to the fuel/air mixture when applying carb. heat?

Answer 9

Mixture becomes richer

Question 10

What does the throttle do?

Answer 10

Allows the pilot to manually control the amount of fuel/air mixture that enters the cylinders.

Question 11

What does the mixture control do?

Answer 11

It regulates the fuel-to-air ratio

Question 12

What type of ignition system does your aircraft have?

Answer 12

It is provided by 2 engine-driven magnetos and 2 spark plugs per cylinder.
The ignition system is independent of the electrical system.

Question 13

What are the main advantages of a dual ignition system?

Answer 13

1) it increases safety (if one fails you still have the other)
2) more complete and even combustion of the mixture
- i.e. improved engine performance

Question 14

What type of fuel system does your aircraft have?

Answer 14

Gravity-feed system

Question 15

What is the purpose of the fuel tank vents?

Answer 15

It provides a way of replacing fuel with outside air, preventing a vacuum.

Question 16

What is the function of the manual primer?

Answer 16

It provides assistance in starting the engine by drawing fuel from the fuel strainer and injects it directly into the cylinder intake ports.

Question 17

What is the electrical system in your aircraft?

Answer 17

Electrical energy is provided by a 28 volt, direct current system powered by an engine driven 60 amp alternator and a 24 volt battery.

Question 18

What does the ammeter indicate?

Answer 18

The flow of current, in amperes, from the alternator to the battery or the battery to the electrical system.

Question 19

Why is the alternator voltage slightly higher than the battery voltage?

Answer 19

It keeps the battery charged.

Question 20

How does cabin heat work?

Answer 20

Fresh air is heated by an exhaust shroud and then directed to the cabin through a series of ducts.

Question 21

What are the 5 basic functions of engine oil?

Answer 21

Lubricates
Cools
Removes
Seals
Cleans

Question 22

What anti-icing equipment is your aircraft equipped with?

Answer 22

Heated pitot tube

Carburetor heat

Question 23

Define: Detonation

Answer 23

An uncontrolled, explosive ignition of the fuel/air mixture

Question 24

What are the common causes of detonation?

Answer 24

Lower than recommended fuel grade
High power and lean mixture
Extended ground operations

Question 25

Define: Pre-ignition

Answer 25

Occurs when the fuel/air mixture ignites prior to the engines normal ignition

Question 26

What is the Make and Horsepower of the engine in your aircraft?

Answer 26

Lycoming

160 HP
