More than a century has passed since humans conquered the sky. Like any conquest, it required assuming countless risks to achieve it.

Once achieved, the process of consolidation begins, along with stabilization. Time and hard work are what allow this stabilization to be secure.

Just like in every human conquest, this process has not escaped the chronological logic of growth. Of course, aviation is not exempt from this developmental mechanism of conquests.

Unfortunately, for this industry, the process of growth comes with the loss of lives. After more than a century of conquest, it could be said that the aviation industry is in the stabilization phase, achieving established, reliable, and sustainable safety standards.

If we have reached this stage, it is the result of work, research, study, and the construction of what we now know as a safety culture. The conquest of the sky and safe aviation require constant actions to maintain and increase the levels of safety that have been achieved.

That is why this work highlights the most significant aspects of the development of concepts and techniques that have served, served, and will continue to serve flight crews in maintaining and improving the mentioned standards. .
