Quiz: 6 Questions To See How Well You Know Aircraft Systems

Let's see what you know!


  1. 1) In a carbureted engine, airflow that passes through the Venturi...
    Wikipedia

    Due to Bernoulli's principle, the speed of a fluid and the pressure associated with it are inversely proportional. That is, if the speed of the fluid (air) increases, the pressure decreases and vise versa.

  2. 2) The engine driven alternator fails in a single-alternator aircraft. What happens?
    chimothy27

    If your alternator fails, it will no longer be charging the battery, and if your aircraft isn't equipped with a standby or emergency battery, the electrical load will be drawn from the main battery. This would eventually lead to a complete electrical failure if immediate actions aren't taken.

  3. 3) When you extend flaps on your aircraft. What does it do to your performance?
    Corey W. Watts

    Extending your flaps lowers your stall speed and allows you to fly a steeper approach at a slower airspeed.

  4. 4) In most small piston aircraft, the heater works by ducting fresh air around what?
    sstrubel

    Fresh air passes through an exhaust shroud that surrounds the exhaust manifold. This heats up the air, which then goes to the cabin.

  5. 5) What is the purpose of oil in reciprocating engines?

    The main purposes are for cooling, sealing, cleaning, and lubricating. For constant-speed propeller aircraft, oil actuates the propeller as well.

  6. 6) Which aircraft instruments get information from the static port?
    Bin im Garten

    The airspeed indicator, vertical speed indicator, and altimeter all use static air. The airspeed indicator also uses ram air from the pitot tube to measure airspeed.
