AVIA 305 Quiz
- Question 1 A Normal shock wave will have what effect on velocity and Mach number? Selected Answer: Decrease to subsonic - Question 2 2.5 out of 2.5 points The Airplane Flying Handbook describes Medium Turns (20 to 45 of bank) as those in which the angle of bank remains nearly constant. This type of turn demonstrates Selected Answer: Neutral lateral stability - Question 3 2.5 out of 2.5 points If an aircraft that has been disturbed from its equilibrium position has the initial tendency to return to it's original equilibrium position, it is demonstrating Selected Answer: Positive Static Stability - Question 4 2.5 out of 2.5 points The Airplane Flying Handbook describes Steep Turns (>45 of bank) as those resulting from a degree of bank at which the airplane exhibits this type of lateral stability Selected Answer: Negative - Question 5 2.5 out of 2.5 points The upward inclination of a wing or horizontal stabilizer to the horizontal plane is referred to as Selected Answer: Dihedral - Question 6 2.5 out of 2.5 points Rudder usage may be necessary during a coordinated turn due to the tendency for Selected Answer: Adverse yaw - Question 7 2.5 out of 2.5 points The first aircraft to be designed, produced and flown with an aerodynamically 2.5 out of 2.5 points
unstable design was the Selected Answer:
F- 16
- Question 8
Positiv e Dynamic Stability
- Question 15 The speed of sound in air is a function of alone. 2.5 out of 2.5 points
Selected Answer: Temperature
- Question 16 2.5 out of 2.5 points Aircraft speeds where the airflow around the aircraft is Mach 0.7 or less is Selected Answer: Subsonic - Question 17 2.5 out of 2.5 points If an aircraft is rolled into a given bank, released, and continues to roll further into a steeper bank demonstrates Selected Answer: Negative lateral stability - Question 18 Transonic flight problems may include 2.5 out of 2.5 points Selected Answer: All of the above - Question 19 2.5 out of 2.5 points An increase in wing sweep will have what effect on supersonic flight? Selected Answer: The aircraft can fly faster due to a reduced drag coefficient - Question 20 2.5 out of 2.5 points An oscillation where the airspeed, pitch, and altitude of the airplane vary widely, but the AOA remains nearly constant is referring to Selected Answer: Phugoid longitudinal dynamic mode - Question 21 2.5 out of 2.5 points If an aircraft is rolled into a given bank, released, and rolls back to zero bank by itself demonstrates Selected Answer: Positive lateral stability - Question 22 A "stable" aircraft wing design is one where the 2.5 out of 2.5 points
Answer:
- Question 24 2.5 out of 2.5 points If an aircraft that is trimmed for non-sideslip flight is subjected to a sideslip condition (i.e., crosswind) and then reacts by turning away from the new relative wind, thus increasing the sideslip angle, is said to have Selected Answer: Negative directional stability - Question 25 2.5 out of 2.5 points As the airflow passes over the airfoil, its speed increases and, somewhere on the surface of the airfoil, its speed reaches a maximum value of Mach 1 before completely passing over the airfoil and returning to its freestream airspeed. The airspeed that the aircraft is flying when this condition occurs is Selected Answer: Critical Mach - Question 26 2.5 out of 2.5 points If an aircraft that has been disturbed from its equilibrium position has the initial tendency to move farther away from its equilibrium position, it is demonstrating Selected Answer: Negative Static Stability - Question 27 An "unstable" aircraft wing design is one where the 2.5 out of 2.5 points Selected Answer: CG is aft of the Center of Lift - Question 28 2.5 out of 2.5 points If an aircraft that is trimmed for non-sideslip flight is subjected to a sideslip condition (i.e., crosswind) and then reacts by turning into the new relative wind so that the sideslip angle is reduced to zero, is said to have Selected Answer: Positive directional stability - Question 29 2.5 out of 2.5 points If an aircraft has been disturbed from its equilibrium position and the maximum displacement increases with time, it is said to have Selected Answer: Negative Dynamic Stability
- Question 30 2.5 out of 2.5 points Normally, the ailerons are used to produce rolling moments, however, the can also produce rolling moments
