How does the 3P model differ from the DECIDE model?

The 3P model, which stands for Perception, Process, and Perform, is characterized as a continuous loop that emphasizes the ongoing nature of decision-making in aviation. This model requires pilots to constantly perceive their environment and any changes, process the information they gather, and perform the necessary actions based on that data. As situations evolve, the cycle repeats to ensure that the pilot's assessment and responses are current and relevant.

In contrast to being a one-time process, the continuous nature of the 3P model allows pilots to adapt to changes dynamically, reinforcing the importance of vigilance and flexibility in decision-making. This continuous loop helps pilots remain aware of ongoing conditions, such as changes in weather or aircraft performance, ensuring that decisions are made based on the most current information available.

This distinction in how the 3P model operates compared to the DECIDE model, which can sometimes be perceived as more linear, highlights the importance of maintaining a proactive and responsive approach in dynamic flight environments.
