Q
  1. What is a magneto, and how does it work?
A

Engine-driven, self contained units providing electrical current w/o using an external power source of power. Must be actuated by battery for start, but that’s it

Q
  1. What does a carburetor do, and what type does the Archer have?
A

Mixes fuel and air to form combustible mixture. Fuel-injected

20
Q
  1. Why do we experience a RPM drop when applying carb heat?
A

warm air is less dense = less air for the engine, resulting in less performance

21
Q
  1. What does the throttle do?
A

Allows pilot to manually control amount of fuel/air ratio entering the cylinders. Results in change in engine speed and power

22
Q
  1. What does the mixture control do?
A

Regulattes fuel to air ratio. Prevents fuel/air mixture from becoming to rich at higher altitudes due to decreasing air density. Can lead to fouling of spark plugs

23
Q
  1. What type of landing gear does the Archer have?
A

Tricycle-type. Two fixed main wheels and a steerable nosewheel

24
Q
  1. What type of fuel system does the Archer have?
A

Fuel-Pump system

25
Q
  1. What type of fuel is allowed in the Archer?
A
  • 100LL = Blue
  • 100 = Green
26
Q
  1. What color would you get if you mixed 100LL & 100 together?
A

clear

27
Q
  1. What is the fuel capacity of the Archer?
A

50 gallons, 48 useable

28
Q
  1. What is the purpose of a primer, and how does it work?
A

Provides assistance in starting the engine. Draws fuel from fuel strainer and injects it directly into the cylinder intake ports. Result is quicker, more efficient engine start

29
Q
  1. What is detonation?
A

Uncontrolled, explosive ignition of the fuel/air mixture within cylinder’s combustion chamber. Causes excessive pressure and temps in engine

30
Q
  1. What causes detonation?
A
  • Lower fuel grade than required
  • Operating with extremely high manifold pressure & low RPM
  • High power setting, with excessively lean mixture
  • Extended ground ops or steep climbs with reduced cylinder cooling
31
Q
  1. What is the oil capacity of the Archer?
A

8 quarts

32
Q
  1. What is the function of oil?
A
  • Lubricates
  • Cools (reduces friction)
  • Removes heat from cylinders
  • Seals, provides seal between cylinder walls and pistons
  • Cleans
33
Q
  1. Oil temperature max for Archer?
A

245 F (118C)

34
Q
  1. Oil pressure min and max for Archer?
A

25 PSI - 115 PSI

35
Q
  1. Briefly describe the electrical system of the Archer
A

POH 7.21
- 28V electrical system
- 24V primary battery,provides electricity when engine isn’t running
- 70 ampere alternator, provides electricity when engine is running
- Voltage regulator, regulates electrical system to 28V to prevent damage
- 24V Emergency battery

36
Q
  1. What bus is “standby battery” connected to?
A
  • Essential bus
37
Q
  1. What instruments operate on the pitot-static system?
A
  • Airspeed indicator
  • Altimeter
  • Vertical speed indicator
38
Q
  1. Why is the airspeed indicator the only PS instrument connected to both pitot tube and static port?
A

Because to get our velocity it has to compare our pitot air to static air since the pitot air accounts for both our velocity and pressure

39
Q
  1. What instruments contain gyroscopes?
A
  • Turn coordinator
  • Heading indicator
  • Attitude indicator
40
Q
  1. What are the two principles of a gyroscope?
A
  • Rigidity in space
  • Precession
41
Q
  1. How does a vacuum system operate?
A

Engine driven vacuum pump provides suction

42
Q
  1. How does the magnetic compass work?
A

Magnetized needles fastened to a float assembly with a compass card, align parallel to the earths lines of magnetic force. Housed in a bowl of white kerosene (compass fluid)

43
Q
  1. What are the errors associated with the magnetic compass?
A

VDMONA:
Variation
Deviation
Magnetic dip
Oscillation
Northerly turning tendencies
Acceleration/deceleration errors

44
Q
  1. What type of brake fluid and color dose the Archer have?
A

Hydraulic, red (MIL-PRF-5606)

45
Q

What anti-icing equipment does the Archer have?

A

Alternate air, pitot heat
