100% VERIFIED ANSWERS |ALREADY GRADED A+
What are the things that give us longitudinal stability? Correct answer-CG
Wing Placement
Canard
Airspeed
Trim
Tail Volume
Horizonal Tail
dynamic stability is Correct answer-overtime
static stability is Correct answer-The initial tendency of an object to move toward or away from its
original equilibrium position.
What is a Phugoid? Correct answer-exchange of kinetic energy for potential
what do dorsal fins add? Correct answer-Directional Stability
What is a bank without a turn called? Correct answer-Side Slip
Roll due to Yaw is caused by Correct answer-Side force of the vertical tail
Speed differential of the wings
Yaw due to Roll Correct answer-is adverse yaw
What causes adverse yaw? Correct answer-down aileron produces more drag and lift
nose pulled in direction of raised wing
aileron left, nose goes right
aileron right, nose goes left
use rudder to coordinate turns
what is dutch roll Correct answer-Lateral directional oscillation
when we are trimmed in level flight we are trimmed to an Correct answer-airspeed
wing sweep increases what two types of stability? Correct answer-Lateral and Directional
What are the 4 turning tendencies? Correct answer-P-factor
Torque
Gyro
Slip stream
3 corrections to the turning tendencies Correct answer-Offset Fin
offset engine
, AOI differential
2 elements of p-factor Correct answer-relative wind
AOA differential
2 turning tendencies in a steep turn Correct answer-p-factor
torque
what causes a sideslip? Correct answer-bank without a turn
what causes a spin? Correct answer-stall with sideslip that results in autorotation
what is a Stall? Correct answer-an increase in AOA beyond the CAOA resulting in a loss of lift
is total pressure constant? Correct answer-In a closed system total pressure is constant
what are the 3 things that high lift devices provide? Correct answer-change in camber
increase surface area
add energy to the boundary layer
how is AOA measured? Correct answer-between the chordline and the relative wind
total pressure is made up of? Correct answer-static and dynamic pressure
what is V glide and how is it calculated? Correct answer-best glide
trail and error
what is force divergence? Correct answer-sharp increase in drag as we reach subsonic speeds (3x
the multiplier)
what are the three types of forces? Correct answer-Shear, tension and compression
what are the two types of flow Correct answer-convergent and divergent
newtons third law as it relates to aircraft Correct answer-airflow goes down aircraft goes up (equal
and opposite)
what happens to performance as weight increases Correct answer-performance decreases
what happens to performance as altitude increases? Correct answer-performance decreases
3 types of hydroplaning Correct answer-Dynamic, viscous, and reverted rubber
what must tail down force equal in level flight Correct answer-lift weight coupling
fuselage destabilizer
thrust
drag
weight pitch moment
What effects L/D max Correct answer-nuthing
