The 5P process helps a pilot recognize  the physiological situation at the end of the flight before  takeoff and continues to update personal conditions as the  flight progresses. Once risks are identified, the pilot is better  equipped to make alternate plans that lessen the effects of  these factors and provide a safer solution.  One of the key differences between CRM and SRM is the  way passengers interact with the pilot. The pilot of a single- engine aircraft enters into a very personal relationship with  the passengers. In fact, the pilot and passengers sit within  arm’s reach all of the time.  [Figure 6-18]  If the capabilities of a passenger sitting next to the pilot are  not being utilized, the pilot is limiting the potential for a  successful flight. Passengers can read checklists, verify PIC  performance of an action, re-verify that the gear is down and  the lights are on, look for other aircraft, and even tune radios.  The failure of a pilot to integrate the passenger at some level  of assistance is almost as bad as not utilizing a pilot in that  seat. Another person onboard is a resource for the PIC to  Sometimes passengers also have their own priorities that  influence the PIC. The desire of the passengers to make  use. A bonus is heightened passenger appreciation for GA  through the participation in the flight.  I llness— Do I have any symptoms?
