Explain the process of calculating the center of gravity shift caused by unloading passengers from the front of an aircraft first.

Calculating the center of gravity (CG) shift caused by unloading passengers from the front of an aircraft first requires understanding weight and balance principles and using the aircraft's loading manifest and weight and balance data. The first step is to determine the initial CG location of the aircraft before unloading. This information is found on the aircraft's loading manifest, which is prepared before each flight. The manifest indicates the aircraft's weight and CG location at takeoff. Next, estimate the weight of the passengers being unloaded from the front of the aircraft. This can be done by using an average passenger weight, typically around 170-200 pounds per person, including carry-on baggage. Count the number of passengers being ....
