Final answer:
The subject concerning the changes in an airplane's center of gravity due to fuel burn is related to aerospace engineering and involves the principles of physics and fuel management. The 'Gimli Glider' incident exemplifies the catastrophic effects of inaccuracies in fuel measurements and the importance of understanding aircraft balance and structure.
Step-by-step explanation:
The change in the center of gravity (CG) in an airplane due to fuel consumption is a significant aspect of aerospace engineering. As the fuel is burned during a flight, the mass distribution of the airplane changes, potentially affecting the flight dynamics and the aircraft's balance. The famous incident of the Gimli Glider highlights the importance of proper fuel management, where the Boeing 767 ran out of fuel mid-flight due to a unit conversion error. This aircraft, which unexpectedly became a glider, successfully landed at Gimli Industrial Park Airport. The incident occurred during the transition from the English to the metric system, causing the crew to load only half of the needed fuel. It serves as a reminder of the critical importance of vigilance regarding fuel calculations and monitoring the aircraft's CG.
