1
An index unit is
Force x Arm divided by a factor
None of the above
Force x Arm
the distance from the datum
2
The Alpha loading system does not use Force x Arm
True
False
3
In weight and balance calculations, arm is _____
the distance between the datum line and CG.
the distance between the datum line and the item.
the distance between the items.
weight times moment.
4
Why is weight and balance calculated for aircraft ?
To alter the CG if the plane is not loaded in the CG limit
Passenger and crew comfort
To reduce aerodynamic drag
Safety of passengers and crew
5
The distance between where a seat is located and the datum is
Changes during flight
The Force
is not relevant to loading
is given in the flight manual
6
an airport of 100' elevation that has a temperature of 34 degrees will have ( when compared to ISA)
better performance
I don't know
degraded performance
same as ISA performance
7
At an airport with an elevation of 2000ft and temperature of 20degC, what is the ISA deviation?
ISA +20C
ISA -4C
ISA +11C
ISA+9C
8
MOMENT in weight and balance is
A concept in probability theory and statistics
A medieval unit of time
The product of weight multiplied by arm
9
Why does atmospheric pressure decrease with height?
There are less clouds as height increases.
There is no gravity at high altitudes.
The amount of air particles decreases as height increases.
Air weighs less at high altitudes.
10
An increase in temperature will
mean it is warmer
Will decrease an aircraft performance
Have no effect on aircraft performance
Have a positive effect on performance
11
Aircraft performance data can be found in
The flight manual
The certificate of airworthiness
The Maintenance release
The SOP's
12
Why is Weight and Balance important?
B: important for safe and efficient flight
A: An aircraft is a dynamic device
D: An aircraft is a static device
C: Both A and B
13
For weight and balance computations, weight x arm equals
The distance that the CG moves
The force the horizontal stabilizer must create
The momentum of the load at that location
The total moments for that weight and location
14
what is moment in weight and balance?
the horizontal distance from the datum
the distance between the forward and rearward CG limits
the product of the weight and the arm
the product of the weight and the tare
15
Weight and balance is also known as?
Balance table
Load manifest
Load control
Load sheet
16
An airport of 100' elevation and QNH 1013 will have a pressure height of
240'
-240
64'
100'
17
One of the first major innovations in aircraft performance was the invention of

Conventional landing gear
18
Does Weight and balance play a vital part in aircraft performance
False
True
19
Long wet grass will affect take off performance by
Will improve rate of acceleration
will slow acceleration to lift off speed
making the aircraft roll easier
20

Singapore
Sydney
Denmark
New York
21
An uphill slope during landing
Will shorten the landing distance
will have no effect on distance required
Will lengthen the landing distance
