SRM and the 5P Check  1-16 Figure 1-9.  The 5P checklist.  The 5 Ps are based on the idea that the pilot has essentially five variables that impact his or her environment and that can cause the  pilot to make a single critical decision, or several less critical decisions, that when added together can create a critical outcome. This  concept stems from the belief that current decision-making models tend to be reactionary in nature. A change must occur and be  detected to drive a risk management decision by the pilot. For instance, many pilots use risk management sheets that are filled out by  the pilot prior to takeoff. These form a catalog of risks that may be encountered that day and turn them into numerical values. If the  total exceeds a certain level, the flight is altered or canceled. Informal research shows that while these are useful documents for  teaching risk factors, they are almost never used outside of formal training programs. The 5P concept is an attempt to take the  information contained in those sheets and in the other available models and use it.  The 5P concept relies on the pilot to adopt a scheduled review of the critical variables at points in the flight where decisions are most  likely to be effective. For instance, the easiest point to cancel a flight due to bad weather is before the pilot and passengers walk out  the door to load the aircraft. So, the first decision point is preflight in the flight planning room, where all the information is readily  available to make a sound decision, and where communication and Fixed Base Operator (FBO) services are readily available to make  alternate travel plans.  The second easiest point in the flight to make a critical safety decision is just prior to takeoff. Few pilots have ever had to make an  emergency takeoff. While the point of the 5P check is to help the pilot fly, the correct application of the 5P before takeoff is to assist  in making a reasoned go/no-go decision based on all the information available. These two points in the process of flying are critical  go/no-go points on each and every flight.  SRM sounds good on paper, but it requires a way for pilots to understand and use it in their daily flights. One practical application is  called the “Five Ps” (5 Ps).$_{ }$ [Figure 1-9]  The 5 Ps consist of “the Plan, the Plane, the Pilot, the Passengers, and the Programming.”  Each of these areas consists of a set of challenges and opportunities that face a single pilot. And each can substantially increase or  decrease the risk of successfully completing the flight based on the pilot’s ability to make informed and timely decisions. The 5 Ps are  used to evaluate the pilot’s current situation at key decision points during the flight, or when an emergency arises. These decision  points include preflight, pretakeoff, hourly or at the midpoint of the flight, predescent, and just prior to the final approach fix or for  visual flight rules (VFR) operations, just prior to entering the traffic pattern.  SRM is about gathering information, analyzing it, and making decisions. Learning how to identify problems, analyze the information,  and make informed and timely decisions is not as straightforward as the training involved in learning specific maneuvers. Learning  how to judge a situation and “how to think” in the endless variety of situations encountered while flying out in the “real world” is$_{ }$ more difficult. There is no one right answer in ADM; rather, each pilot is expected to analyze each situation in light of experience  level, personal minimums, and current physical and mental readiness level, and make his or her own decision.
