Weight And Balance Flashcards
1
Q
Excessive weight reduces flight performance in these ways:
A
Higher takeoff speed Longer takeoff run Reduced rate and angle of climb Lower max altitude Shorter range Reduced cruising speed Reduced maneuverability Higher stalling speed Higher approach and landing speed Longer landing roll Excessive weight on nose or tail wheel
2
Q
Weight of avgas per gallon
A
6lbs
3
Q
CG too far forward results in
A
Problems controlling and raising the nose especially in t.o. And landing
4
Q
CG too far aft results in
A
Serious effect to longitudinal stability
Reduced ability to recover from stalls and spins.
Produces very light control forces peering pilot to inadvertently overstress an aircraft

Q
CG is:
A
The imaginary point at which all the weight is concentrated
7
Q
Arm is:
A
The distance from the datum to any component
Forward of the datum is negative
Aft of the datum is positive
8
Q
Moment =
A
Weight x arm
9
Q
Change in cg math
A
(Weight shifted/total weight)=(delta CG/distance weight is shifted)
