Modern aircraft are designed to operate under various stressors, one of which is weight. Although the exact capacity that each plane can tolerate differs significantly, an average-sized commercial aircraft typically holds 175,000lbs upon takeoff. With such immense weight applied to the vessel, it is critical for the flight crew to perform accurate calculations that can accurately determine the aircraft's center of gravity while also predicting if that point will change during flight. These requirements are called load and trim calculations, and this area of aircraft safety is tightly regulated by FAA mandates. In this blog, we will discuss the procedures and calculations associated with aircraft load in trim while also discussing the risks associated with improper estimations.
