What effect does windshear have during an approach for landing?
The aircraft’s dynamic speed is reduced as a result of the reduction in wind speed. The effective aircraft weight is increased as a result of experiencing a downdraft, which requires the pilot to recover the flight path by pitching the aircraft up.

- Wing tip stall
- Pitch up
- Wing flexing
- Dutch roll (positive contribution to LATERAL stability)
- High drag at high alpha
tendency is particular to a swept wing aircraft mainly because of the high local Cl loading it experiences.

An anabatic wind is one which?
During the day, the incoming solar radiation warms up the slope. The air expands and becomes less dense, so it starts to ascend, creating a low-pressure area over the slope. This leads to the upward motion of the air from the valley to the top of the mountain, which is called an anabatic wind or upslope wind. If this process is strong enough and the ascending air contains sufficient moisture, then the water vapor starts to condensate, leading to the development of cumulus clouds and precipitation.

How does a forward center of gravity affect the stall speed, and why?
A center of gTavity forward of the center of pressure will cause a higher stall speed.
This is so because a forward center of gTavity would cause a natural nose-down attitude below the required en route cruise attitude for best performance. Therefore, a downward force is induced by the stabilizer to obtain the aircraft’s required attitude. However, this downward force is in effect a weight and thereby increases the aircraft’s overall effective weight. Weight is a factor ofthe stall speed, and the heavier the aircraft, the higher is the aircraft’s stall speed.
Conversely, the opposite is true: A center of gravity aft of the center of pressure will cause a lower stall speed.
What is Mach tuck?
Mach tuck is the nose-down pitching moment an aircraft experiences as it passes its critical Mach number (Merit).
Mach tuck is a form of longitudinal instability that occurs because of the center of pressure’s rearward movement behind the center of gravity (see preceding question), which induces the aircraft to pitch down (or the aircraft’s nose to tuck).
What are the four reasons for a variable-incidence tailplane/stabilizer, especially on a jet aircraft?
To provide a balancing force for a large center of gravity range
2. To provide a balancing force for a large speed range

4. To reduce elevator trim drag to a minimum
