Four F-16s of the USAF 457th Fighter Squadron flying in a "Finger-four" formation. The finger-four formation (also known as the "four finger formation" and the "Fingertip Formation") is a flight formation used by fighter aircraft. It consists of four aircraft, and four of these formations can be combined into a squadron formation.
[4] [5] He was a pioneer of aeronautical engineering and is sometimes referred to as "the father of aviation." [3] He identified the four forces which act on a heavier-than-air flying vehicle: weight, lift, drag and thrust. [6] Modern aeroplane design is based on those discoveries and on the importance of cambered wings, also proposed by Cayley ...
Aerodynamics work throughout the 19th century sought to achieve heavier-than-air flight. George Cayley developed the concept of the modern fixed-wing aircraft in 1799, and in doing so identified the four fundamental forces of flight - lift, thrust, drag, and weight. The development of reasonable predictions of the thrust needed to power flight ...
In flight a powered aircraft can be considered as being acted on by four forces: lift, weight, thrust, and drag. [1] Thrust is the force generated by the engine (whether that engine be a jet engine, a propeller, or -- in exotic cases such as the X-15-- a rocket) and acts in a forward direction for the purpose of overcoming drag.

Forces of flight on a powered aircraft in unaccelerated level flight. Understanding the motion of air around an object (often called a flow field) enables the calculation of forces and moments acting on the object. In many aerodynamics problems, the forces of interest are the fundamental forces of flight: lift, drag, thrust, and weight. Of ...

He identified the four vector forces that influence an aircraft: thrust, lift, drag and weight and distinguished stability and control in his designs. He developed the modern conventional form of the fixed-wing aeroplane having a stabilising tail with both horizontal and vertical surfaces, flying gliders both unmanned and manned.
