Q

How many spark plugs does the Piper Archer have? And why?

A
  1. Engine ignition is provided through the use of two engine-driven magnetos, which are independent of the aircraft’s electrical system and each other. Each magneto powers one spark plug per cylinder

Q

What causes carburetor icing?

A

This is due to the high air velocity
through the carburetor venturi and the absorption of heat from this air by vaporization of the fuel.

18
Q

What kind of fuel does the Piper Archer use?

A

100 low lead avgas (blue in color)

19
Q

What size fuel tanks does the Piper have?

A

25 Gallon tanks (x2)

20
Q

How many gallons of unusable fuel are there in each tank?

A

21
Q

The Archer is equipped with how many fuel pumps and what powers them?

A

There is one engine-driven and
one electrically driven fuel pump.

22
Q

When is the electric fuel pump used?

A

The electric fuel pump is used for all takeoffs and landings, and when switching tanks.

23
Q

What are the three positions of the fuel selector?

A

The positions are “L”, “R”, and “OFF”.

24
Q

What is the procedure for switching tanks in cruise flight?

A
  1. Electric fuel pump on
  2. Fuel selector from “L” to “R” or from “R” to “L”
  3. Check fuel pressure
  4. Electric fuel pump off
  5. Check fuel pressure
25
Q

When should fuel tanks NOT be changed?

A

During critical phases of flight

26
Q

When should fuel takes be changed?

A

Every 30 minutes and during non-critical phases of flight.

27
Q

The Archer is equipped with what electrical system?

A

The Archer is equipped with a 28-volt DC electrical system and a 24-volt lead acid main battery.

28
Q

How is electrical power supplied?

A

A 70-amp engine-driven alternator.

29
Q

When do you not reset a popped circuit breaker?

A

When smoke can be smelled

30
Q

What do you do in the event of the ALTERNATOR INOP annunciator lighting up?

  • Dual Garmin GNS 430 GPS
33
Q

In the case of a G500 failure, what is the Archer equipped with to handle this situation?

A

-An electrically-powered gyroscopic standby attitude indicator with an
internal battery backup
-A conventional standby altimeter and standby airspeed indicator, connected
to the pitot-static system
-A magnetic compass for heading reference

34
Q

What do you do when you see an amber status LED blinking next to the STBY PWR button?

A

Press and release
the STBY PWR button once to continue the operation of the standby attitude indicator.

35
Q

What are the pilot actions when the Attitude & Heading Reference System (AHRS) fails?

A
  1. Use the standby attitude indicator.
  2. Continue using HSI on PFD. Verify track against magnetic compass heading.
  3. Precision (ILS) and non-precision (GPS, localizer, and VOR) approaches can be accomplished.
36
Q

What are the pilot actions when the PFD fails?

A
  1. Refer to the standby instruments.
  2. Use the GPS CDI page for navigation and approaches.
    CLR - Press and hold for 3 seconds to return to default CDI page
  3. Only GPS non-precision approaches can be accomplished.
37
Q

What are the pilot actions when you experience electrical failure?

A
  1. Use standby attitude indicator. Press the “STBY PWR” button right of the blinking LED to continue operating using its internal battery.
  2. Use standby airspeed, altimeter, and compass.
  3. Declare an emergency and exit IMC as soon as practicable. The manufacturer does not specify the endurance time of the integral
    emergency battery.
38
Q

What are the pilot actions when Air Data Computer (ADC) fails?

A

Use standby airspeed indicator and altimeter.

39
Q

Where is the stall horn located?

A

The leading edge of the left wing.

40
Q

When does the stall horn activate and what sound does it make?
