In the 5P checklist, what does the first "P" stand for?

The first "P" in the 5P checklist stands for "Plan." This emphasizes the importance of thorough planning in aviation, particularly regarding flight operations. Proper planning encompasses various aspects of a flight, including the flight route, weather conditions, aircraft performance, and any potential contingencies. It sets the foundation for safe and effective flight execution, ensuring that all necessary considerations are accounted for before takeoff. This initial focus on planning is crucial for building operational awareness and preparing for necessary adjustments during the flight, highlighting the proactive mindset required of pilots.

In contrast, while the other options present relevant concepts related to aviation, they do not represent the first step in the 5P checklist, which is primarily focused on establishing a solid baseline through planning.
