Part of the answer refers to GPT, GPT_Pro better problem solving
STPA(System theory Process Analysis) is a failure mode and effect analysis tool based on system theory. It is mainly used for the safety evaluation of aircraft systems. It helps pilots and engineers, as well as other practitioners, assess the safety of aircraft systems, identify the possibility that they are unsafe, and take effective action to address the problem.

The use of

STPA has two main steps, one is to conduct failure mode analysis(FMEA), the other is to conduct effect analysis(ETA). FMEA is a safety assessment method based on failure mode, through analyzing various failure modes that may appear on the aircraft, and evaluating their possible impact. ETA is a problem-oriented safety assessment method, which analyzes various problems that may occur on an aircraft and evaluates their possible impact.

To get started with STPA quickly, we must first master the basic principles and processes of STPA use. The STPA uses a standardized process to evaluate aircraft safety. The first step is to analyze the various conditions or failure modes that a pilot, engineer, or other practitioner might encounter while operating the aircraft. On this basis, these situations or failure modes are analyzed, evaluated and judged according to the standard process and flow chart provided by STPA.

Secondly, it is necessary to learn the various mathematical and information tools used in STPA, such as causal graph, semantic net, security hierarchy analysis, algebraic factor decomposition, possibility hidden decomposition, probability calculation, decision tree, neural network, genetic algorithm and Bayesian net. Learn how they work and how to use them, and then use them to help us evaluate aircraft safety.

Finally, learn how to apply STPA to your own paper. Learn how to apply the principles of STPA to your own paper, such as using STPA to analyze possible failure situations or problems on a particular aircraft; STPA is used to evaluate and judge various problems that may occur on specific aircraft. STPA is used to evaluate and judge various risk factors that may appear on the aircraft under specific circumstances. STPA is used to help us find out the unsafe factors on the aircraft and put forward the corresponding countermeasures.

In conclusion, STPA is a good tool, and learning how to use it will greatly help us prepare and evaluate aircraft safety in our paper.
