T/F Wing dihedral is one of the ways that we achieve stability around the longitudinal axis - Answer-
True
E: Roll stability on a low wing aircraft is corrected using a dihedral wing angle. In normal flight the
Bernoulli effect (lift) does not pul...
E:1) Use the vertical stabilizer (If the aircraft yaws one way... Camber airflow on one side increases...
Bernoulli one side 1 increases... Bernoulli on side 2 decreases... this creates sideways lift... which pulls
the aircraft back straight)
2) Swept back wings (Changes the induced drag and parasite drag on each side).
What produces pitch stability on a standard aircraft? - Answer✔✔-Both B and C are correct (The
horizontal stabilizer pulls down and using a dihedral wing angle)
E: Pitch stability is primarily due to the constant downward pull on the tail, and small automatic changes
on the horizontal tail, preventing the CG from oscillating up and down
T/F Pitch stability is considered to be longitudinal stability? - Answer✔✔-True
E:
Yaw= Stability around the vertical axis (Directional Stability)
Pitch= Stability around the lateral axis (Longitudinal Stability)
Roll= Stability around the Longitudinal axis (Lateral Stability)
Which of the following is not an advantage of a high wing aircraft? - Answer✔✔-Easier to build strong
landing gear support
