12.68.8(b) . aircraft weight; 

The higher the aircraft weight the higher the IAS speed
The lower the aircraft weight the lower the IAS speed

12.68.8(a) . load factor; 

At an increased load factor the stalling speed IAS increases significantly

12.68.8. Explain how the stalling IAS is affected by:

12.68.6(b) . a reduction in angle of attack is critical to recovery. 

12.68.6(a) . the stall is associated with a particular angle of attack and not a particular airspeed; 

The stalling angle of attack when measured using the original flaps up Chordline

12.68.6. Explain how:

12.68.4. Describe the symptoms of a developing stall.

Airspeed will be reducing
The controls become less effective
Turbulent wake casues a Buffet
Just prior to the stall the aircraft sinks – further reducing the angle of attack

12.68.2(b) . reduction of lift and increase of drag. Sub Topic Syllabus Item 

The pressure distribution below the lower surface of the aerofoil disappears at an increased angle of attack. Toward the rear there will be an area of decreased static pressure.
Lift is decreased and drag is increased as a result

12.68.2(a) . disruption of streamline flow over the upper surface of the aerofoil; 

On the upper surface of the aerofoil as the angle of attack is increased the airflow must deviate from its free-stream path and accetlerate to follow the contour of the surface. Static pressure above the wing decreases.
At the angle of attack the airflow can no longer conform so separates from most of the upper surface to form a large turbulent wake

12.68.2. Describe the stalling angle of attack, with reference to:
