20 questions
Question 1: The maximum governor fitted to some gas turbine engines is sensitive to changes in fuel specific gravity.
A. Yes
B. No
Explanation: The study materials state that the maximum governor fitted to some gas turbine engines is sensitive to changes in specific gravity and would require adjustment if a different specific gravity fuel was used.
Question 2: Which of the following indications are typically provided by the fuel system instrumentation on large aircraft?
A. Fuel quantity, fuel pressure, and fuel temperature
B. Position of cross-feed and shut-off valves
C. Status of fuel pumps (on or off) and fuel used per engine
D. Aircraft altitude and engine RPM
Explanation: According to the study materials, large aircraft fuel system instrumentation provides information not only on fuel quantity and pressure, but also fuel used, position of various valves (e.g., cross-feed, inter engine, firewall shut-off), pump status (on or off), and fuel temperature. These are often presented as 'mimic' diagrams or electronic schematic displays. Aircraft altitude and engine RPM are not listed as typical fuel system instrumentation indications.
Question 3: The primary function of a fuel heater in turbine engine aircraft fuel systems is to drain accumulated water from the bottom of the fuel tanks.
A. Yes
B. No
Explanation: A fuel heater in turbine engine aircraft fuel systems is provided to prevent water in the fuel from freezing and blocking fuel filters, and to remove any ice crystals that may have formed. Water drains are used to drain water off the bottom of the tank after it has settled.
Question 4: What is the natural color characteristic of turbine fuels for identification?
A. They are dyed green or blue for specific grades.
B. They retain their natural color, which can range from straw yellow to completely colourless.
C. They are always colourless and transparent for easy identification of contaminants.
D. They are typically a light red or orange hue due to additives.
Explanation: Turbine fuels are not dyed for identification. They retain their natural colour, which can range between a straw yellow to completely colourless.
Question 5: Is the primary purpose of the fail-safe circuit in a capacitive fuel gauging system to prevent the indicator from showing less fuel in the tank than there actually is?
A. Yes
B. No
Explanation: The fail-safe circuit drives the gauge pointer slowly towards the empty position to prevent the indicator from showing that there is more fuel in the tank than there actually is, not less.
