Q

This stalls are normally encountered during takeoff, climb-out, and go-arounds when the pilot fails to maintain proper control due to premature flap retraction or excessive nose-high trim.

Q

Stalls can be recognized by

A

mushy feeling in the flight controls

less control effect as the aircraft’s speed decreases.

reduction in control effectiveness is primarily due to reduced airflow over the flight control surfaces

a loss of revolutions per minute

a reduction in the sound of air flowing along the fuselage

buffering of stall horn, uncontrollable pitching, or vibrations

Sinking feeling

Q

What is Stability?

A

is the characteristic of an airplane in flight that causes it to return to a condition of equilibrium, or steady flight, after it is disturbed.

Q

Types of Stability

A

Static Stability
Dynamic Stability
Static and Dynamic Stability
Longitudinal Stability
Lateral Stability
Directional Stability

18
Q

The initial tendency to return to the position from which it was displaced is termed

A

Static Stability

19
Q

Static Stability Can be described as:

A

POSITIVE STATIC STABILITY
NEGATIVE STATIC STABILITY
NEUTRAL STATIC STABILITY

20
Q

AN AIRCRAFT’S INITIAL TENDENCY TO RETURN TO ITS ORIGINAL POSITION ONCE DISTURBED

A

Positive Static Stability

21
Q

TENDENCY TO CONTINUE AWAY FROM THE ORIGINAL POSITION

A

Negative Static Stability

22
Q

TENDENCY TO REMAIN AT THE NEW POSITION.

A

Neutral Static Stability

23
Q

However, since the aircraft doesn’t immediately return to the original position, but instead does so over a period of time through a series of successively smaller oscillations,

A

Dynamic Stability

24
Q

3 classifications of dynamic stability

A

POSITIVE DYNAMIC STABILITY

NEUTRAL DYNAMIC STABILITY

NEGATIVE DYNAMIC STABILITY

25
Q

IS THE TENDENCY OF AN AIRCRAFT TO DAMPEN TOWARD ORIGINAL POSITION ONCE DISTURBED

A

Positive Dynamic Stability

26
Q

IS THE TENDENCY OF AN AIRCRAFT TO DAMPEN BACK TO ITS ORIGINAL POSITION ONCE DISTURBED TO A NEW POSITION

A

Neutral Dynamic Stability

27
Q

IS THE TENDENCY OF AN AIRCRAFT TO TREND AWAY FROM ITS ORIGINAL POSITION ONCE DISTRUBED

A

Negative Dynamic Stability

28
Q

THE TENDENCY OF AN AIRCRAFT TO RETURN TO THE TRIMMED ANGLE OF ATTACK.
STABILITY ABOUT THE AIRPLANE’S LATERAL AXIS

A

Longitudinal Stability

29
Q

THE TENDENCY OF AN AIRCRAFT TO RESIST ROLL.

STABILITY ABOUT THE AIRPLANE’S LONGITUDINAL AXIS

A

Lateral Stability

30
Q

THE TENDENCY OF AN AIRCRAFT TO RESIST YAWING.
STABILITY ABOUT THE AIRPLANE’S VERTICAL AXIS

A

Directional Stability

31
Q

A usually beneficial influence on aircraft performance which occurs while you are flying close to the ground. It results from a reduction in upwash, downwash, and wingtip vortices which provide a corresponding decrease in induced drag.

A

Ground Effect
