In this introduction lecture to flight mechanics Dr. Ir. M. Voskuijl starts off by explaining the way pilots perform their climb, and the method of performing calculations on it. This leads to the derivation of the equations of motion of a climbing aircraft and using these, an example of a crashed Boeing is explained. With the equations of motions derived, a solution can be found for the rate of climb, and conclusions are drawn about the way excess power is used to both climb and accelerate the aircraft. Finally using these equations, an example exam question is solved.
