Answer:
"The performance of an aircraft is the product of its design capabilities in terms of aerodynamics, and environmental influences that affect these capabilities. The way in which an airplane performs in flight is important to know in advance, since the very standards in aviation related to take-off speeds, stall speeds, manageable load, and numerous other airplane maneuvers are dependent on certain criterion to ensure safe flight. This criteria is often referred to as performance limitations.
Establishing performance limitations is fundamental to the safe handling of an aircraft and is indirectly related to economic aspects of commercial aviation. When an engineer sits down to formulate an airplane design, the first item on his/her checklist is the aircraft performance.
Any modification to the aircraft or a new structure being added to the airplane which, in future, would compromise the aircraft performance, is simply crossed off. Atmospheric characteristics such as pressure, density, temperature, and humidity play a crucial role in altering the efficacy of the airplane engine and/or the aerodynamic capability of the aircraft to fly, thus affecting the aircraft performance."
