If an aircraft has positive STATIC stability, which is true of the aircraft?
a - The aircraft attempts to return to straight and level but constantly overshoots
and continues to oscillate at a constant rate
b - The aircraft does not display any tendency to return to straight and level but
stays at whatever attitude it is
placed.
c - Displays a tendency to want to return to straight and level.
d - The aircraft does not remain at straight and level without constant attention -
ANSWER A
If an aircraft has neutral DYNAMIC stability, which is true of the aircraft?
A - The aircraft attempts to return to straight and level but constantly over
shoots and continues to oscillate at a constant rate.
B - The aircraft does not display any tendency to return to straight and level but
stays at whatever attitude it is placed.
C - The aircraft returns to straight and level flight through a series of constantly
reducing oscillations.
D - The aircraft does not remain at straight and level without constant attention.
- ANSWER C
True or False:
Under a POSITIVE G load maneuver the pilot feels lighter in the seat. -
ANSWER False
True or False:
The smaller the radius of a turn, the greater the g-forces. - ANSWER True
True or False:
Static stability describes how an object returns to its home state or "null". -
ANSWER False
True or False: As bank angle increases, G-forces increase. - ANSWER True
,True of False: As bank angle increases, the speed at which the airplane stalls
decreases. - ANSWER False
True of False: A Utilify category aircraft is certified for lower G-forces than a
normal category aircraft. - ANSWER False
True or False:
In order to have Static Stability, you must have positive Dynamic Stability. -
ANSWER False
True or False:
Negative Static Stability says that an object continually wants to move away
from null or home. - ANSWER True
Why would we want anhedral on a wing?
A - The aircraft has a very heavy and low center of gravity.
B - It makes the aircraft more stable than dihedral.
C - The wing withstands greater G-forces than a wing with dihedral. -
ANSWER A
Which of the following is NOT one of the ways that an airplane gains stability
around the vertical axis?
A - Use a vertical stabilizer near the back of the aircraft.
B - Use swept back wings.
C - Move the center of gravity behind the center of lift. - ANSWER C
How do we create yaw stability on an aircraft?
A - Put a vertical stabilizer on the tail of the aircraft.
B - Sweep the wings backwards.
C - Use dihedral wing angle
D - Only a and b are correct. - ANSWER D
What produces pitch stability on a standard aircraft?
A - The tail adds drag to the aircraft.
B - The horizontalstabilizer pulls downward.
C - The horizontal stabilizer constantly changes AOA with pitch to dampen the
pitching motion.
, D - Both b and c are correct. - ANSWER D
True or False: Pitch stability is considered to be longitudinal stability. -
ANSWER True
True or False: Wing dihedral is one of the ways that we achieve stability around
the longitudinal axis. - ANSWER True
True of False: Wing dihedral must be greater on high wing aircraft than on a
low wing aircraft. - ANSWER False
How does dihedral make an airplane stable? (Be careful there is some tricky
wording in this question.)
A - It moves the center of gravity aft allowing the lift to directly oppose gravity.
B - The wing that falls, results in a Bernoulli force that directly opposes gravity,
and lifts the wing back up.
C - The actual Bernoulli aerodynamic force diminishes on the rising wing and
the wing falls. - ANSWER B
True or False:
High wing aircraft have natural stability because the CG is below the lift. -
ANSWER True
Which of the following is NOT one of the ways that swept back wings provide
yaw stability for an aircraft that
inadvertently yaws to the right.
A - The wing left wing tip produces more induced drag and that pulls the
aircraft back left.
B - The lift becomes greater on the right wing and the airplane rolls and then
yaws back to the left.
C - The parasite drag becomes greater on the left wing and the aircraft yaws
back left and flies straight. - ANSWER A
Which of the following is NOT an advantage of a high wing aircraft?
A - Better lift/drag ratio
B - Better lateral (roll) stability
C - Shorter landing distance
D - Easier to build strong landing gear support - ANSWER D
