Show Answers:

  1. Describe the nosewheel landing gear of the airplane
    tubular spring steel main gear strut that provides main gear shock absorption lubercated by oil and air
  2. How is steering accomplished on your plane?
    Push -pull steering rod which is connected to the rudder pedals.
  3. What time of engine does your aircraft have?
    110 horsepower engine four cylinder horizontally composed overhead valve, air-cooled, carbureted engine which manufactured by Lycoming.
  4. What does the carburetor do?
    Mixes fuel and air for a combustible mixture.
  5. What happens to the fuel and air mixture when carburetor heat is applied?
    The mixture becomes rich, has a higher ratio of fuel because air is less dense when it is heated.
  6. What two things does the throttle do?
    1. regulates the speed and power

    2. controls the amount of fuel and air entering the cylinders
  7. What does the mixture do?
    control the fuel and air ratio
  8. What is the purpose of the mixture at high altitudes?
    At high altitudes the mixture may become too rich due to low air density in high altitudes so the mixture control can prevent that by the pilot leaning the mixture
  9. What does the mixture do in regards to fuel conservation?
    The mixture allows the pilot to conserve fuel by providing optimum power.
  10. What happens when the fuel leve in an aircraft fuel tank decreases?
    A vacuum would be created within the tank which would eventually result in a decreasing flow of fuel and engine stoppage most likely
  11. What doe fuel vents provide?
    fuel vents provided outside air to replace decreasing fuel which aids in preventing the formation of a vacuum.
  12. Where does the manual primer drawl fuel from when it is pulled out?
    the fuel strainer
  13. Where does fuel drawl from the primer go?
    to the cylinder intake ports
  14. Why use a primer?
    to provided an efficient engine start
  15. describe the electrical system of the aircraft
    electrical energy is provided by a 28 volt, direct current system powered by an engine-drive 60 amp alternator and a 24-volt battery
  16. What is the difference between circuit breakers and fuses?
    Circuit breakers are the same as fuses except when they are overloaded they can be reset only once.
  17. What is used for a source of electrical energy in the aircraft?
    a 24 volt batter
  18. What does the ammeter indicate?
    the amount of current in amperes fro mthe alternator to the battery


    the battery to the airplane electrical system
  19. What does the ammeter indicate when the master switch is on and the engine is on?
    a charging rate to the battery
  20. What does the ammeter show when the alternator is not functioning?
    Discharging the battery
  21. What six lighting systems does the electrical system power and provide?
    1. landing light

    2. strobe lights

    3. position lights

    4. taxi lights

    5. instruments lights

    6. interior light
  22. How does the aircraft cabin heat work?
    Fresh air, heated by an exhaust shroud, is directed to the cabin through a series of ducts.
  23. How can temperature be regulated in the cabin?
    By pushing the "push pull" cabin heat and carbin air
  24. Where is cabin air vented?
    Below the pilot and passenger feet
  25. How do you get cabin ventilation?
    pull the CABIN AIR knob out
  26. How do you get maximum cabin heat?
    by pushing CABIN AIR completely in and by pulling CABIN HEAT completely out
  27. When is cabin air and cabin heat being vented while in the aircraft?
    at the bottom of the passengers and pilot's feet
  28. What are two types of oil that can be used for the plane?
    1. mineral oil

    2. ashless dispersant oil
  29. What is mineral oil generally used for ?
    breaking in a new engine
  30. What is ashless dispersant oil used for ?
    anti wear properties avoids carbon particles from building up

    picks up contamination prevent sludge from forming in the engine
