Q

What is the oil system process?

A
  1. Engine-driven oil pump pumps the oil from the oil sump (bottom of the engine) up to the oil filter
  2. Filter filters oil
  3. If oil is cool, flows through the vernatherm; if oil hot, flows to oil cooler
  4. Flows to engine & does its job at the engine
  5. Collects at oil sump and begins again
17
Q

Describe the fuel system process.

A
  1. Fuel leaves tank, passes maintenance fuel drains and gascolator (filter) to Dukes electric fuel pump.
  2. Electric fuel pump provides positive pressure and allows fuel to flow to the fuel shutoff valve, past the firewall to the engine driven fuel pump.
  3. Engine driven fuel pump provides positive pressure to the fuel control unit
  4. Fuel control unit (controlled by throttle) measures out fuel and it goes to the fuel distribution manifold
  5. Fuel distribution manifold distributes it through the four fuel injector nozzles, one for each cylinder
18
Q

When does the alternator/generator act as the normal source of power?

A

When the engine is running

19
Q

When is the battery the source of power?

A

When alternator is inop (prior to engine start or after alternator failure)

20
Q

Where is the pitot and what flight instruments does it support?

A

Bottom of left wing.

Airspeed, altimeter, vertical speed indicator, transponder mode c

21
Q

Which flight instruments require the vacuum pump?

A

Attitude indicator and heading indicator (vacuum spins a gyro)

22
Q

Which instruments function off a gyro?

A

Heading indicator, attitude indicator, turn coordinator
