A V-n Diagram, also known as a velocity-load factor or flight envelope diagram, graphically represents the operational limits of an aircraft in terms of its load factor against velocity. It is crucial for understanding the performance characteristics, safety margins, and stress limits of an aircraft under various flight conditions.

Operational limits define the boundaries within which a system or process can function effectively and safely, ensuring optimal performance without causing damage or failure. Understanding and adhering to these limits is crucial for risk management, efficiency, and compliance with regulatory standards.

Load factor is a measure of the efficiency of electrical power usage, indicating the ratio of average load to peak load over a specific period. A higher load factor signifies a more stable and efficient use of energy resources, reducing the need for additional capacity and lowering costs.

Safety margins are critical buffers incorporated in design, engineering, and decision-making processes to account for uncertainties and ensure reliability under variable conditions. They provide a cushion against errors, unforeseen events, or deviations from expected performance, enhancing overall safety and functionality.
