SPC Weight and Balance 2

Question 1

What is the 'center of gravity' (CG) of an aircraft?

Accepted Answer

The point through which the total weight of the aircraft acts vertically downward

Answer

The geometric center of the fuselage

Answer

The midpoint between the nose and tail

Answer

The point directly above the main landing gear

Question 2

What effect does exceeding the maximum gross weight have on an aircraft's stall speed?

Accepted Answer

Stall speed increases

Answer

Stall speed decreases

Answer

Stall speed remains unchanged

Answer

Stall speed is not affected by weight

Question 3

A pilot calculates the total moment for a loaded aircraft. The next step to find the actual CG location is to:

Accepted Answer

Divide total moment by total weight

Answer

Multiply total moment by total weight

Answer

Subtract total weight from total moment

Answer

Add total weight to total moment

Question 4

What is a 'moment envelope' (CG envelope) used for in weight and balance?

Accepted Answer

Determining approved CG range at various aircraft weights

Answer

Calculating fuel burn rates during flight

Answer

Establishing maximum takeoff distances

Answer

Recording aircraft maintenance history

Question 5

Which of the following is generally NOT included when calculating an aircraft's useful load?

Accepted Answer

Permanently installed avionics

Answer

Pilot and passengers

Answer

Usable fuel

Answer

Baggage

Question 6

As fuel is consumed during flight, how might the aircraft's CG change?

Accepted Answer

CG movement depends on where the fuel tanks are located relative to the CG

Answer

CG always moves forward as fuel burns

Answer

CG always moves aft as fuel burns

Answer

CG does not change as fuel burns

Question 7

What is 'tare weight' in the context of aircraft weight and balance?

Accepted Answer

The weight of equipment such as chocks or blocks that is placed on the scales during weighing but is not part of the aircraft

Answer

The weight of passengers and baggage

Answer

The weight of unusable fuel

Answer

The maximum allowable takeoff weight
