Q01. Search and list out the total weight of various types of aircrafts.      Aircraft Gross Weight: The aircraft gross weight (also known as the all-up weight and abbreviated AUW) is the total aircraft weight at any moment during the flight or ground operation. An aircraft's gross weight…

Q01.  For a defined driving cycle, calculate the energy required for braking. Solution: Under the condition of braking, some amount of energy is required to do the same as that of energy required for accelerating the vehicle. Hence to calculate energy, we use the acceleration energy equarion, Calculating the…
