Quiz: Weight and Balance

Question 1

In order for it to be safe to fly an aircraft the center of gravity…:

Answer 1

• Must fall in the acceptable range from the Datum

Question 2

Heading towards the tail, the arm length is:

Answer 2

• Positive (+)

Question 3

Heading towards the tail the arm length is:

Answer 3

• Positive (+)

Question 4

The main reason weight changes during an airplane’s flight is:

Answer 4

• Burning of the fuel

Question 5

A stall occurs because:

Answer 5

• The angle attack is so great that the air flowing OVER the wing causes the plane to spin
• Airflow SEPERATES from the wing

Question 6

How do you get out of a stall?:

Answer 6

• Reduce the angle of attack (Nose down by pushing the yolk)
• Add power (increase airspeed)
• Use rudder to maintain coordination
• Raise flaps and landing gear

Question 7

The datum is ALWAYS located at:

Answer 7

• Wherever the manufactured decided it would be

Question 8

One consequence of the Center of gravity being too far aft is:

Answer 8

• The plane might not be able to recover from a stall

Question 9

Which of the following is NOT used to mitigate a plane from stalling?:

Answer 9

• Airfoil

Question 10

A spin follows a stall because:

Answer 10

• Stalls produce LESS LIFT on one of the wings causing the plane to turn

Question 11

Which of the following will NOT cause a stall?:

Answer 11

• Too forward of a Center of Gravity

Question 12

What is Wing Washout?:

Answer 12

• Twisting of the wings to make sure aileron control isn’t stalled
• Gives the opportunity for pilots to recognized a stall

Question 13

What are wing vortex generators?:

Answer 13

• A design that keeps a STREAM of air over the wing (The video about the strings)
• Less leakage and drag

Question 14

Where will be the centre of mass of a uniform rod lies?:

Answer 14

• At its middle point

Question 15

What are Mitigate Stalls?:

Answer 15

• Keeps aircraft controlled
• Gives pilots a warning to prevent stalling

Question 16

How do you find the Center of Gravity?:

Answer 16

• Total Moment DIVIDED by Total Weight

Question 17

How do you find the Total Moment?:

Answer 17

• Weight x Arm

Question 18

What are the Chambers?:

Answer 18

• A teardrop shaped, more curved
  ~ The greater the wing chamber, the higher stalling angle of attack
• Helps maintain the effectiveness of aileron’s

Question 19

What are the 4 components that help prevent a stall?

Answer 19

• Mitigate Stalls
• Chamber
• Wing Washout
• Vortex Generators
