8157-2. Which of the following have an effect on aircraft CG results when
conducting a weight and balance check?
A- Leaving the parking brake on.
B- Leaving the parking brake off.
,C- Leaving the downlocks installed.
Give this one a try later!
B- Spirit level.
The leveling means for determining weight and balance is specified by the
aircraft manufacturer and is listed in the Type Certificate Data Sheets. Proper
level may be determined with spirit levels placed across leveling lugs or
along the door sill.
A- parallel to the centerline of the airplane.
An arm, used in determining the CG of an airplane, is the horizontal distance from the datum
to the center of gravity of the item. An arm is always measured parallel to the centerline of
the airplane.
C- Leaving the downlocks installed.
All of the required equipment must be properly installed,and there should be no
equipment installed that is not included in the equipment list.
B- repairs and alterations.
, Changes of fixed equipment may have a major effect upon the weight of an aircraft. Many
aircraft are overloaded by the installation of extra radios or instruments.

8189. If the empty weight CG of an airplane lies within the empty weight CG
limits,
A- it is necessary to calculate CG extremes.
B- it is not necessary to calculate CG extremes.
C- minimum fuel should be used in both forward and rearward CG checks.
Give this one a try later!
, A- reduction or loss of effective cyclic pitch control.
If a helicopter is loaded in such a way that its CG is either too far forward or too far aft, flight
will be hazardous.
The cyclic pitch control will likely not be effective enough to control the helicopter against
its out-of-balance condition.
A- parallel to the centerline of the airplane.
An arm, used in determining the CG of an airplane, is the horizontal distance from the datum
to the center of gravity of the item. An arm is always measured parallel to the centerline of
the airplane.
B- it is not necessary to calculate CG extremes.
If the empty weight CG of an airplane lies within the empty weight CG limits, it is not
necessary to calculate the CG extremes.
The airplane cannot be legally loaded in such a way that either its forward or aft CG
limits can be exceeded.
