GENERAL: WEIGHT AND BALANCE EXAM WITH ALL
CORRECT & 100% VERIFIED ANSWERS (ALREADY
GRADED A+)
When computing the maximum forward loaded CG of an aircraft, minimum weights, arms, and
moments should be used for items of useful load that are located aft of the Correct answer-
forward CG limit.
All other things being equal, if an item of useful load located aft of an aircraft's CF is removed, the
aircraft's CG change will be Correct answer-forward in proportion to the weight of the item and its
location on the aircraft.
The empty weight of an airplane is determined by Correct answer-subtracting the tare wight from
the scale reading and adding the weight of each weighing point.
The amount of fuel used for computing empty weight and corresponding CG is Correct answer-
unusable fuel.
In a balance computation of an aircraft from which an item located aft of the datum was removed,
use Correct answer-(-)weight*(+)arm(-)moment.
Which statement is true regarding helicopter weight and balance? Correct answer-Wight and
balance procedures for airplanes generally also apply to helicopters.
The maximum weight of an aircraft is the Correct answer-empty weight plus useful load.
When accomplishing loading computations for a small aircraft, necessary information obtained from
the weight and balance records would include Correct answer-current empty weight and empty
weight CG.
In the process of weighing an airplane toward obtaining the CG, the arms from the weighing points
always extend Correct answer-parallel to the centerline of the airplane.
The useful load of an aircraft consists of the Correct answer-crew, usable fuel, passengers, and
cargo.
The major source of weight change for most aircraft as they age is caused by Correct answer-
repairs and alterations.
Maximum zero fuel weight is the Correct answer-maximum permissible weight of a loaded aircraft
(passengers, crew, and cargo) without fuel.
What should be clearly indicated on the aircraft weighing form? Correct answer-Weighing points.
When determining the empty weight of an aircraft, certificated under current airworthiness
standards (14 CFR Part 23), the oil contained in the supply tank is considered Correct answer-a part
of the empty weight.
In theory of weight and balance, what is the name of the distance form the fulcrum to an object?
Correct answer-Lever arm.
, An aircraft with an empty weight of 1500 pounds and an empty weight CG of +28.4 was altered as
follows:
1. two 12-pound seats located at +68.5 were removed
2. structural modifications weighing +28 pounds were made at +73
3. a seat and safety belt weighing 30 pounds were installed at +70.5
4. radio equipment weighing 25 pounds was installed at +85.
what is the new empty weight CG? Correct answer-+30.30.
When dealing with weight and balance of an aircraft, the term 'maximum weight' is interpreted to
mean the maximum Correct answer-authorized weight of the aircraft and its components.
Find the empty weight CG location for the following tricycle-gear aircraft. Each main wheel weighs
753 pounds, nosewheel weighs 22 pounds, distance between nosewheel and main wheels is 87.5
inches, nosewheel location is +9.875 inches from the datum, with 1 gallon of hydraulic fluid at -21.0
inches included in the weight scale. Correct answer-+96.11 inches.
What tasks are completed prior to weighing an aircraft to determine its empty weight? Correct
answer-Remove all items except those on the aircraft equipment list; drain fuel and fill hydraulic
reservoir.
The maximum weight as used in weight and balance control of a given aircraft can normally be found
Correct answer-in the Aircraft Specification or Type Certificate Data Sheet.
(1) Private aircraft are required by regulations to be weighed periodically. (2) Private aircraft are
required to be weighed after making any alteration. Regarding the above statements, Correct
answer-neither No. 1 nor No. 2 is true.
If an empty weight CG of an airplane lies within the empty weight CG limits, Correct answer-it is
not necessary to calculate CG extremes.
An aircraft had an empty weight of 2886 pounds with a moment of 101,673.78 before several
alterations were made. The alterations included:
1. removing two passenger seats (15 pounds each) at +71
2. installing a cabinet (97 pounds) at +71
3. installing a seat and safety belt (20 pounds) at +71
4. installing radio equipment (30 pounds) at +94.
The alterations caused the new empty weight CG to move Correct answer-1.62 inches aft of the
original weight CG.
An aircraft with an empty weight of 1800 pounds and an empty weight CG of +31.5 was altered as
follows:
1. two 15-pound passenger seats located at +72 were removed
2. structural modifcations increasing the weight 14 pounds were made at +76
3. a seat and safety belt weight 20 pounds were installed at +73.5
4. radio equipment weighing 30 pounds was installed at +30.
What is the new empty weight CG? Correct answer-+31.61.
Which would have an effect on aircraft CG results when conducting a weight and balance check?
Correct answer-Leaving the downlocks installed.
