Federal Aviation Regulations (FAR) 135 Oral Practice Test

The main idea is that the Weight and Balance specification in Ops contains the data and limits used to load the aircraft safely for flight. It tells you how much weight you can carry, where that weight can be placed (the center of gravity and the moment arms for items like fuel, passengers, baggage, and cargo), and the maximum allowable weights (takeoff, landing, and operating envelopes). Crews use this information to calculate the total loaded weight and the aircraft’s balance before flight, ensuring the airplane remains within the certified limits and will perform predictably and safely. This isn’t about maintenance scheduling, passenger seating arrangements, or cargo handling procedures—those are covered by other parts of operations. The weight and balance data specifically guide how loading affects stability, controllability, and performance.
