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.

7
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.

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

IS THE TENDENCY OF AN AIRCRAFT TO DAMPEN TOWARD ORIGINAL POSITION ONCE DISTURBED
Positive Dynamic Stability
26
IS THE TENDENCY OF AN AIRCRAFT TO DAMPEN BACK TO ITS ORIGINAL POSITION ONCE DISTURBED TO A NEW POSITION
Neutral Dynamic Stability
27
IS THE TENDENCY OF AN AIRCRAFT TO TREND AWAY FROM ITS ORIGINAL POSITION ONCE DISTRUBED

28
THE TENDENCY OF AN AIRCRAFT TO RETURN TO THE TRIMMED ANGLE OF ATTACK. STABILITY ABOUT THE AIRPLANE’S LATERAL AXIS
Longitudinal Stability
29

Lateral Stability
30
THE TENDENCY OF AN AIRCRAFT TO RESIST YAWING. STABILITY ABOUT THE AIRPLANE’S VERTICAL AXIS
Directional Stability
31
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.
