Q

How do the fuel tanks feed the engine?

A

PA-28-181:
The fuel is fed either from the left or right fuel tank as selected by the fuel selector valve in the cockpit. The fuel is pumped through the fuel strainer either by the electric, engine drive, or both fuel pumps. From there it is pumped into the carburetor where it is mixed with air and distributed to the cylinders.

PA-28-181: No more than 175 RPM drop on each magneto and no more than 50 RPM difference in between the two mags.

22
Q

What should you do if the oil pressure goes to zero and the temperature starts to rise rapidly?

A

Land as soon as possible and investigate cause. Prepare for power off landing

23
Q

What does it mean when after you have actuated the carburetor heat then the rpm drops and then rises on its own?

A

It means carburetor icing was present

24
Q

What is the first thing you should do if the engine begins to lose rpm and run a little rough?

A

Engage carburetor heat

25
Q

29
Q

What should you do if your load meter indicates an excessive load?

A

PA-28-181:
Most likely faulty voltage regulator

Alt switch off
Bat switch On
Reset alt circuit breaker

Else Alt switch off bat switch as required land as soon as possible. prepare for full electrical failure

30
Q

What should you do if your load meter indicates a lower-than-expected load?

A 
PA-28-181:
turn on some equipment and look for load indication
Alt switch off
Check Alt breaker 
Alt switch ON
If power is not restored alt switch off 
reduce electrical load and land as soon as practical
31
Q

What should you do if your low-voltage light illuminates

A

Check load meter to verify inop. alt (zero)

32
Q

What is the gross weight of the airplane?

A

N5676V: Empty weight 1518.25lb + people + baggage + fuel = gross weight

33

A

N5676V: 1,518.25 (AC W&B Sheet)

34
Q

Where is the exact empty weight and the empty center of gravity found?

A

The aircraft W&B document inside the aircraft

35
Q

What is the maximum ramp weight?

40
Q

What is the minimum octane that is to be used in the airplane?

A

PA-28-181: 100

41
Q

When ground handling the airplane with a towbar, how much can the nose gear be turned right or left?

A

PA-28-181: 20 degres left/right of center

42
Q

What kind of oil is used in the airplane?

A

PA-28-181: Ashless mineral oil - SAE 50 (Aeroshell 100)

SAE 50 but can vary depended on ambient temp.

43
Q

As density altitude increases, what happens to performance?

A

Performance decreases

44
Q

How much air pressure should be kept in the tires?

A

PA-28-181:
Nose Gear: 18 psi
Main Gear: 24 psi

45
Q

How does carburetor ice form?

A

The pressure drop in the venturi causes the air to cool and draw heat away from the surrounding metal of the carburetor venturi. Ice can then collect on the cooled carburetor throat.
