AE105

Question 1

What is the difference between maximum endurance and maximum range?

Answer 1

a. Maximum endurance: Greatest amount of time an aircraft can remain airborne for a given amount of fuel.
b. Maximum range: Greatest distance an aircraft can travel for a given amount of fuel.

Question 2

What is the definition of best glide speed and what is it for the T-6A?

Answer 2

a. Best glide speed is that airspeed that gives the maximum range in a power-off glide.
b. Best glide speed for a clean T-6A is approximately 125 KIAS (L/D airspeed)

Question 3

What is the region of reverse command?

Answer 3

Region of thrust/power required curve left of minimum thrust/power required point. In the region of reverse command, more power is required at slower airspeeds to maintain level flight.

Question 4

What control input is needed to compensate for torque effect?

Answer 4

Right rudder

Question 5

If the propeller rotates clockwise, torque is what direction?

Answer 5

Opposite or counterclockwise

Question 6

What causes P-factor?

Answer 6

One propeller blade creating more thrust than its opposing blade

Question 7

What control inputs are necessary to perform a coordinated, level turn? What is the proper balance ball indication during the turn?

Answer 7

a. Stick:
1) Moved in the direction of turn
2) Neutral after turn established

b. Rudder:
1) Applied in the direction of turn
2) Neutral after bank established

c. Stick: Back pressure
d. PCL: Increase thrust/power (as required)
e. Balance Ball: Centered

Question 8

What are the causes and differences between a slip and a skid? Which one is more dangerous in-flight?

Answer 8

a. Slip:
1) Insufficient or opposite rudder
2) Ball deflected inside
3) Turn radius increases
4) Turn rate decreases

b. Skid:
1) Too much rudder
2) Balance ball outside
3) Turn radius decreases
4) Turn rate increases

c. Skids are more dangerous at low altitude and low airspeed

Question 9

Why does an aircraft experience more G forces in a level turn than in straight-and-level flight?

Answer 9

a. In a turn, total lift must be greater than 1 G so the vertical component of lift equals weight.
b. More bank = More total lift required

Question 10

Why does an aircraft experience more G forces in a level turn than in straight-and-level flight?

Answer 10

1) Symmetric: Elevator deflection only

2) Asymmetric: Aileron/rudder deflection with elevator deflection

Question 11

What is the difference between symmetric and asymmetric G-loading?

Answer 11

a. In a turn, total lift must be greater than 1 G so the vertical component of lift equals weight.
b. More bank = More total lift required

Question 12

What is the difference between symmetric and asymmetric G-loading?

Answer 12

1) Symmetric: Elevator deflection only

2) Asymmetric: Aileron/rudder deflection with elevator deflection

Question 13

What is stability? What is the difference between static and dynamic stability?

Answer 13

a. Stability: Tendency for an object to return to a state of equilibrium when disturbed
b. Static stability: Initial tendency of an object to move toward or away from its original equilibrium position
c. Dynamic stability: Position or motion of object over time after being disturbed from equilibrium

Question 14

What is the relationship between aircraft stability and aircraft maneuverability?

Answer 14

They are opposites

1) Stable aircraft are harder to maneuver (transports)
2) Aircraft easier to maneuver are less stable (fighters)

Question 15

What is the difference between sideslip angle and sideslip relative wind?

Answer 15

a. Sideslip angle: Difference between flight path and longitudinal axis
b. Sideslip relative wind: Component of the relative wind parallel to the lateral axis

Question 16

When do pilot induced oscillations (PIOs) occur and what is the remedy if a PIO occurs?

Answer 16

a. Pilot induced oscillations (PIOs) occur when the pilot over controls the aircraft in response to short period pitch and AOA oscillations. This over control leads to oscillations which increase in amplitude over time.
b. Problem is corrected by neutralizing stick or freezing stick just aft of center.

Question 17

Of the factors affecting takeoff and landing performance, what is the single largest contributor to increasing takeoff or landing distance?

Answer 17

Weight is the greatest factor. Doubling weight quadruples both takeoff and landing distance.

Question 18

Why is it impossible to exceed the aircraft load limit at airspeeds below cornering velocity?

Answer 18

Cornering velocity is the minimum airspeed at which the aircraft G-load limit can be obtained. Below this airspeed the aircraft will stall, making an over-G condition impossible.

Question 19

What is the difference between positive and negative static stability?

Answer 19

The vertical stabilizer is the greatest positive contributor to directional static stability due to its weathervane effect.

Question 20

What is the difference between maximum rate of climb and maximum angle of climb?

Answer 20

a. Maximum Rate of Climb: Maximum altitude gained in a given amount of time.
b. Maximum Angle of Climb: Maximum altitude gained for distance traveled.
