An item located at station +50 would have an arm of how many inches?

Explanation:
In weight and balance, the arm is the distance from the reference datum to the item along the airplane’s length. The station tells you where the item is located, and its value in inches from the datum is used as the arm. So a station of +50 means the item is 50 inches forward of the datum, giving an arm of 50 inches. That’s why 50 inches is the correct choice. If the station were 0, the arm would be 0 inches; 25 or 75 would correspond to 25 or 75 inches, respectively, not 50.
