Q

What is the Alternator Control Unit?

A

The alternator control unit is a voltage regulator that controls the rate of charge to the battery.

17
Q

How is the cabin heated.

A

Air passes by the exhaust and muffler then into the cabin.

18
Q

Describe how the VSI works.

A

Contains a diaphragm with a calibrated leak.

19
Q

What would you do if the aircraft was a quart low on oil?

A

Add oil as per instructions in the POH.

20
Q

If the alternator fails during flight, will the engine quit as a result?

A

No, the magnetos supply power to the spark plugs in the engine.

21
Q

How many times does a crankshaft turn 360 degrees during a 4 stroke engine cycle.

A

2

22
Q

Describe what happens during preignition in a piston engine.

A

The fuel/air mixture ignites prior to normal ignition event.

23
Q

Describe the engine in your aircraft.

A

Lycoming
IO-360-B4A
180 hp @ 2700 RPM
Fuel injected
Direct drive
Naturally aspirated
Horizontally opposed

24
Q

Describe the electrical system for your aircraft.

A

The airplane is equipped with a 28 volt alternator and a 24 volt system.

25
Q

How many spark plugs does the Archer III have?

A

2 per cylinder
8

26
Q

How many quarts of oil does the Archer III hold?

A

6-8

27
Q

What type of fuel do we use? What color is it?

A

AVGAS 100LL
Blue

28
Q

Describe how the airspeed indicator works.

A

The ASI uses both the Pitot, as well as the static system. The ASI introduces the static pressure into the outer case while the pitot pressure is introduce into the diaphragm. The dynamic pressure expands or contracts the diaphragm with is connected to the indicating system.

29
Q

What is ADF

A

Automatic Direction Finding

30
Q

What is a magnetometer

A

Device that measures strength of Earth’s magnetic field. (one on each wing in the archer)

31
Q

What function does an ADC serve in a Glass Cockpit flight display.

A

Air Data Computer is a solid-state device that takes pitot and static air pressure inputs and computes airspeed, altitude and vertical speed

32
Q

What function does the AHRS serve in a glass cockpit flight display?

A

The “Attitude and Heading Reference System” is a solid-state system that replaces free-spinning gyros to generate pitch and bank info.

33
Q

What is DME

A

distance measuring equipment for VOR

34
Q

The green arc on the airspeed indicator is…

A

The normal operating range
