Is the third step in establishing a helicopter landing zone to establish control facilities?

Establishing control facilities is not the third step in the process of establishing a helicopter landing zone. The primary steps typically include selecting the landing area, marking the landing zone, and then establishing control measures which may include control facilities. The confusion may arise from various operational contexts where control facilities are vital, but they are not always a step in the initial establishment of a landing zone.

This highlights the importance of understanding not just the sequence of steps, but also their relevance to different mission types and environments. In non-combat scenarios, for example, control facilities may be less emphasized to allow for a more streamlined process, while highlighting the safety and efficiency of the landing operations. Thus, the answer is indeed that it is false that establishing control facilities is the third step, as the priorities can differ based on specific operational needs and circumstances.
