The principles of aeroplane flight are based on the idea that power is the true secret of flight. Speed and surface are the controlling factors in flight, and while surface may be eliminated, speed is absolutely necessary.

This chapter discusses the concept of fore and aft control in flying machines, which is crucial for maintaining stability and control during flight. The author explains that the bird-type of fore and aft control, where the body is caused to oscillate on a vertical fore and aft plane, is not suitable for aeroplanes due to the fixed wing structure. Instead, the author suggests a new principle where the sustaining planes are hinged to the body, allowing for synchronous movement with the tail. This design prevents the pendulous motion that can occur when the power ceases, making the machine safer and more stable. The author also discusses the importance of the low center of gravity in aeroplane design and how it can be achieved by placing the weight below the planes. Additionally, the author touches on the concept of fore and aft oscillations and how they can be prevented by increasing the area of the tail and making it a true supporting surface.
