Mock and Scenarios Questions

Question 1

Explain how a carburetor works

Answer 1

The carburetor is part of the induction system in the aircraft, it is the one in charge of mixing the air and fuel that goes to the engine. The carburetor works by using a venturi to create a vacuum that draws fuel into the airstream and accelerates the air, causing it to mix and vaporize with the fuel

Question 2

Why does the primer only prime 3 cylinder and and not all 4?

Answer 2

Because we don’t have a manifold pressure gauge so the primer only goes to cylinder 1,3 and 4.

Question 3

Is the unusable fuel and oil taken into account for empty weight?

Answer 3

Yes, it is inaccessible so it is taken into account for empty weight

Question 4

Where does the carb heat air come from?

Answer 4

It comes from the exhaust shroud.

Question 5

Describe the electrical system of the aircraft

Answer 5

The Archer we fly is equipped with a 28-Volt direct current electrical system, a 24-volt main battery, and an isolated 24 volt emergency battery. Electrical power is supplied by a 70-amp engine driven alternator. A voltage regulator maintains a constant 28 volt output from the alternator. The Main battery is used as a source of emergency electrical power and for engine starts.

Question 6

What would happen if we lose the alternator and subsequently the main battery?

Answer 6

If we lose the alternator, we would still have the battery to provide electrical power for about 30 minutes before it dies. If the main battery can no longer provide adequate power, and the emergency battery switch is in the arm position, the emergency battery will automatically begin providing power to the emergency bus.
