Question 5

Center of Gravity (CG)

Answer 5

Balance point, is the point at which all of the weight of the aircraft is concentrated.
Three dimensional point with longitudinal, lateral, and vertical positioning in the aircraft.
Total Moment/Total Weight.

Question 6

Gross Weight

Answer 6

Total weight of the airplane .

• Airplane itself
• Pilot and Passengers
• Baggage
• Fuel

Question 7

Empty Weight

Answer 7

• Airplane itself
• Installed items
• Could also include unusable fuels/oil *check POH

Question 8

Arm

Answer 8

Horizontal distance from the datum to the CG of the airplane.

Question 9

Moment

Answer 9

Arm x Weight (measured in pound-inches)

Question 10

Loading Forward CG

Answer 10

Increased Longitudinal Stability
Nose Heavy - excessive loads on the nose wheel
Slower Cruise Speed - requires higher angle of attack (more lift) which results in more drag. Also requires a stronger tail down force.
Higher Stall Speed
Higher Control Forces
Overall Decreased Performance

Question 11

Loading Aft CG

Answer 11

Decreased Static and Dynamic Stability
Control Difficulty
Violent Stall Characteristics - difficult or sometimes impossible to recover from a stall
Light Control Surfaces
More maneuverable - F-18’s fly with Aft CG
Higher Cruise Speed - less tail down force

Question 12

Load Factor

Answer 12

Any force applied to an aircraft to deflect its flight from a straight line produces a stress on its structure. The amount of this force
is the load factor. Measured in G’s.
