18
Q

The horizontal distance from the reference datum to the center of gravity of an item. A plus sign (+) is used if the arm is measured aft of the datum and the minus sign (-) if measured forward of the datum.

A

ARM (MOMENT ARM)

19
Q

The imaginary vertical plane or line from which horizontal distances are measured for aircraft weight and balance purposes.

A

DATUM (REFERENCE DATUM)

20
Q

The product of an item multiplied by its arm and is express in pound – inches (in-lb).

A

MOMENT

21
Q

The maximum weight the floor can withstand per square inch or square foot.

A

FLOOR LOAD LIMIT

22
Q

The average distance from the leading edge to the trailing edge of the wing.

A

MEAN aerodynamic chord (MAC)

23
Q

A location in the aircraft that is identified by a number designating its distance in inches from the datum.

A

STATION

24
Q

EFFECTS OF WEIGHT (1st three)

A
  • cause structural damage on the aircraft
  • reduces fuel efficiency/overconsumption of fuel
  • rate and angle of climb is reduced
25
Q

EFFECTS OF WEIGHT (last four)

A
  • service ceiling is lowered
  • cruising speed is lowered
  • higher take-off speed, resulting in longer take off roll
  • longer landing roll requires higher landing speed
26
Q

1 gal of fuel is equals to?

A

6 lbs (pounds)

27
Q

2 types of unbalancing

A
  • longitudinal unbalance
  • lateral unbalance
28
Q

__ heavy is more recommendable than __ heavy

A

nose, tail
