1
Q

In climbing flight

A

One component of weight acts perpendicular to the flight path and the another component of weight acts rearward, in the same direction as drag

2
Q

Four left-turning tendencies associated with propeller-driven airplanes are

A

Torque, gyroscopic precession, asymmetrical thrust, spiraling slipstream

3
Q

In descending flight

A

One component of weight acts forward along the flight path and another acts perpendicular to the flight path

4
Q

Maintaining the angle of attack that corresponds to L/Dmax will produce

A

The least drag, best glide angle, and maximum gliding distance

5
Q

Changes in weight will not affect

A

Glide ratio but a higher airspeed will have to be maintained in a heavier aircraft in order to cover the same distance over the ground

6
Q

Center seeking force that acts on a turning airplane

A

Centripetal force, which is created by the horizontal component of lift

7
Q

The effects of adverse yaw can be countered by maintaining a coordinated turn using

A

Rudder

8
Q

As angle of bank is increased in a constant airspeed turn

A

The rate of turn increases and radius of turn decreases

9
Q

As airspeed is increased and angle of bank held constant

A

The rate of turn will decrease and turn radius will increase

10
Q

A

The ratio of the weight that the wings must support to the actual weight of the aircraft

11
Q

Accelerated stalls occur

A

When the critical angle of attack is exceeded at an airspeed higher than the one-G stall speed

12
Q

The V-g diagram defines the airplanes

A

Envelope, which is bounded by the stall region, limit load factor, and V^ne

13
Q

The four fundamentals involved in maneuvering an aircraft are

A

Straight-and-level flight, turns, climbs, and descents

14
Q

Torque effect is greatest at

A

Low airspeeds, high power settings and high angle of attack

15
Q

P-factor

A

Causes left yaw at high angles of attack; caused by descending propeller blade on the right producing more thrust than the ascending blade on the left

16
Q

If power failure occurs after takeoff

A

Immediately establish the proper gliding attitude and airspeed

17
Q

The load factor imposed on an airplane will increase

A

As the angle of bank is increased

18
Q

Increasing the load factor will cause an airplane to

A

Stall at a higher speed

19
Q

V^a is

A

Design maneuvering speed

20
Q

The amount of excess load that can be imposed on an airframe

A

Depends on the aircrafts speed
