Final answer:
The statement is False. The airline weighs suitcases when passengers check in, but not the airplane itself.
Step-by-step explanation:
The statement is False.
When passengers check in at an airport, the airline weighs their suitcases to ensure they comply with the weight restrictions and safety regulations for the flight. However, the airline does not weigh the airplane itself when passengers check in.
Weight of an airplane is determined during maintenance checks, where the aircraft is weighed on a special platform called a weighbridge. This helps ensure that the weight of the airplane, including fuel, cargo, and passengers, is within safe limits for takeoff and landing.
