Final answer:
Increased wing loading in aircraft can be caused by higher weight, smaller wings, or both, requiring greater airspeed and pitch to maintain lift. This condition affects rate of descent and can cause a steeper glide path. Pilots can counteract these effects by managing weight, utilizing lift devices, or adjusting engine power.
Step-by-step explanation:
The question seems to be related to the performance of an aircraft, where WS stands for wing loading (weight of the aircraft divided by the area of the wings). An increased performance wing loading typically can be caused by three main factors: increase in aircraft weight, reduction of wing area, or a combination of both. The term a/s refers to airspeed and ROD stands for rate of descent, while GP likely refers to glide path.
When wing loading increases, the aircraft requires a higher airspeed to produce the necessary lift to counteract weight, which can lead to a greater rate of descent if engine power isn't adjusted accordingly. This can affect the glide path negatively, making it steeper. Pitch also typically needs to be increased to maintain altitude at a higher airspeed. To counteract the effects of increased wing loading, pilots can reduce the aircraft's weight if possible, extend lift-enhancing devices like flaps or slats, or adjust engine power to control descent and maintain a proper glide path.
