Airplane Systems Flashcards
What are the 4 main control surfaces?
Elevators
Ailerons
Rudder
Trim Tabs
What is the landing gear on your aircraft?
Tricycle gear with a movable nose-wheel
What is the braking system on your aircraft?
A hydraulic line connects each brake to a master cylinder on each pilot’s rudder pedals
How is steering accomplished on the ground?
Simple mechanical linkage connects the rudder pedals to the nose wheel
Describe the engine on your aircraft?
Horizontally opposed Four cylinder Overhead valve Air cooled Carbureted engine Lycoming 160 HP
What are the 4 engine strokes?
Intake
Compression
Power
Exhaust
What does the carburetor do?
Mixes the fuel and air
How does carb. heat work?
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.
What changes occur to the fuel/air mixture when applying carb. heat?
Mixture becomes richer
What does the throttle do?
Allows the pilot to manually control the amount of fuel/air mixture that enters the cylinders.
What does the mixture control do?
It regulates the fuel-to-air ratio
What type of ignition system does your aircraft have?
It is provided by 2 engine-driven magnetos and 2 spark plugs per cylinder.
The ignition system is independent of the electrical system.
What are the main advantages of a dual ignition system?
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
What type of fuel system does your aircraft have?
Gravity-feed system
What is the purpose of the fuel tank vents?
It provides a way of replacing fuel with outside air, preventing a vacuum.
What is the function of the manual primer?
It provides assistance in starting the engine by drawing fuel from the fuel strainer and injects it directly into the cylinder intake ports.
What is the electrical system in your aircraft?
Electrical energy is provided by a 28 volt, direct current system powered by an engine driven 60 amp alternator and a 24 volt battery.
What does the ammeter indicate?
The flow of current, in amperes, from the alternator to the battery or the battery to the electrical system.
Why is the alternator voltage slightly higher than the battery voltage?
It keeps the battery charged.
How does cabin heat work?
Fresh air is heated by an exhaust shroud and then directed to the cabin through a series of ducts.
What are the 5 basic functions of engine oil?
Lubricates Cools Removes Seals Cleans
What anti-icing equipment is your aircraft equipped with?
Heated pitot tube
Carburetor heat
Define: Detonation
An uncontrolled, explosive ignition of the fuel/air mixture
What are the common causes of detonation?
Lower than recommended fuel grade
High power and lean mixture
Extended ground operations
Define: Pre-ignition
Occurs when the fuel/air mixture ignites prior to the engines normal ignition
What is the Make and Horsepower of the engine in your aircraft?
Lycoming
160 HP
