Weight and Balance

Question 1

Empty weight includes…

Answer 1

fixed ballast, unusable fuel, oil, hydraulic fluid.

Question 2

Residual fuel is…

Answer 2

the fuel that will not normally drain out.

Question 3

Useful load of an aircraft is…

Answer 3

the difference between its empty weight and maximum allowable gross weight.

Question 4

What does not list an aircrafts empty weight?

Answer 4

Aircraft Specification Sheet, Type Certificate Data Sheet, Flight Manual, and Pilots Operating Handbook.

Question 5

Arm is…

Answer 5

the horizontal distance from the datum to the center of gravity of the item.

Question 6

What is the difference between a positive and negative moment?

Answer 6

Positive moment is one that causes the aircraft nose to go up, and a negative moment is one that causes the nose to go down.

Question 7

The useful load of an aircraft is found by…

Answer 7

subtracting the empty weight of the aircraft from the maximum weight.

Question 8

Many aircrafts are overloaded by…

Answer 8

the installation of extra radios or instruments.

Question 9

LEMAC is…

Answer 9

Leading edge of the mean aerodynamic chord.

Question 10

TEMAC is…

Answer 10

Trailing edge of the mean aerodynamic chord.

Question 11

part 23

Answer 11

Applies to most general aviation aircraft, defines empty weight of an aircraft.

Question 12

Empty Weight, according to part 23

Answer 12

includes fixed ballast, unusable fuel, full operating fluids including oil, hydraulic fluid, and other fluids required for normal operation of airplane systems except potable water, lavatory pre-charge water, and water intended for injection in the engines.

When prepping an aircraft for weighing, remove all items except for those on the equipment list, drain fuel, and fill hydraulic reservoir.

Question 13

Useful load

Answer 13

the difference between its empty weight and the maximum allowable gross weight. It does not include any of the fixed or required equipment as these are part of the empty weight.

Question 14

TCDS weight and balance information includes hat?

Answer 14

Yes. TCDS weight and balance information includes hat.

Also, CG range, maximum weight, leveling means, number of seats and location, baggage capacity, fuel capacity, datum location, engine horsepower, oil capacity, amount of fuel in empty weight, and amount of oil in empty weight.

Question 15

When the aircraft is in its level-flight attitude,…

Answer 15

the centers of gravity of all of the items are in their correct locations relative to the datum

Question 16

No federal aviation regulation requires that private planes be weighed periodically

Question 17

When a private aircraft is altered,

Answer 17

the weight and balance records must be updated to show any change hat has been made in the weight or in the empty weight CG location.

These changes are normally found mathematically rather than by weighing the aircraft.

Question 18

Moment

Answer 18

A force that causes rotation about a point.

A positive moment is one that causes the aircraft nose to go up, and a negative moment is one that causes the nose to go down.

Question 19

+ weight, + arm
+ weight, - arm
- weight, + arm
- weight, - arm

Answer 19

- moment
- moment
+ moment

Question 20

How is the useful load of an aircraft found?

Answer 20

by subtracting the empty weight of the aircraft from the maximum weight.

Question 21

The weighing form should include what?

Answer 21

leveling means and location of weighing points

Question 22

The weight and location of what is found in Note 1 in the section of the TCDS, “All pertinent to all models.”

Answer 22

The unusable fuel
