Aircraft Structural Components and Balancing Quiz

What is the position or angle of the main structural components related to in an aircraft?

• Vertical axis and horizontal axis

• Longitudinal axis and lateral axis

• Diagonal axis and vertical axis

• Horizontal axis and diagonal axis

What method is sometimes used for larger aircraft when jacking and balancing?

• Scale method

• Grid method

• Weight method

• Balance method

Where is the grid plate installed in an aircraft?

• On the aircraft ceiling

• On the aircraft wings

• On the aircraft floor or supporting structure

• On the aircraft tail

What is used to level the aircraft?

• A plumb bob
