A high-performance airplane is an airplane with an engine of more than 200 horsepower.
For example, a standard Cessna 172 is not a high performance airplane. A Cessna 182 generally is.
An extra endorsement by a flight instructor is required before a pilot is legally authorized to fly such an airplane.
Here it is in FAA Legalese:
(1) Except as provided in paragraph (f)(2) of this section, no person may act as pilot in command of a high-performance airplane (an airplane with an engine of more than 200 horsepower), unless the person has--
(i) Received and logged ground and flight training from an authorized instructor in a high-performance airplane, or in a flight simulator or flight training device that is representative of a high-performance airplane, and has been found proficient in the operation and systems of the airplane; and
(ii) Received a one-time endorsement in the pilot's logbook from an authorized instructor who certifies the person is proficient to operate a high-performance airplane.
It decreases performance.
Depends on your definition of performance. For speed or economy, either the SR-71 or the Cessna 152.
It reduces climb performance.
The SR-71 is a high-altitude, high-speed reconnaissance aircraft. It carries high performance cameras used in spying.
An airplane with an engine of more than 200 horsepower.
You would have to specify a particular aircraft, "fighter aircraft" is too broad a definition.

Inherent stability is the quality of an aircraft that relates to its tendencies when the pilot releases the controls. Most aircraft are designed such that, if you release the controls the aircraft will naturally tend to level out and fly straight and level. These aircraft are said to be "inherently stable." High-performance aircraft such as fighter planes and aerobatic aircraft often have little or no inherent stability and when the pilot releases the controls the aircraft may bank or pitch in one direction or another. These aircraft take much more skill and concentration to fly safely, so most civilian aircraft are designed to provide a high amount of inherent stability.
Performance is the capability of aircraft at various stages of its flight.The capability may be in terms of weight, Altitude,Speeds, Distances, Gradient/Rate of climb, Obstacle clearance, Maneuverability of rage etc.
The "aoa diagram" is significant in aircraft performance analysis because it shows how the aircraft's angle of attack (aoa) affects its performance, such as lift and drag. Pilots use this diagram to understand the optimal aoa for different flight conditions, helping them to operate the aircraft efficiently and safely.
