The Stacked (or Accordion) Method senger briefing should be accomplished before start - ing the engine, to include information on the proper  use of safety equipment and exiting the aircraft. You  should also inform the passenger as to what to expect  during takeoff, flight, and landing, what feelings and  jolts are normal, what to do if the cart should roll over,  and what to do if the engine fails. Make sure passen- gers are aware of the hazards and risks of a moving  propeller and educate them on the necessity of keep- ing items secured so they don’t get sucked through the  propeller. Help them to secure their helmets (if worn)  and explain how to control the intercom. Show them  where to put their hands and feet and make sure any  cameras or equipment are secure. A passenger should  be aware that an aborted takeoff is always a possibil- ity. Tell them everything depends upon the wing —if  the wing does not inflate properly, or does not inflate  and rotate in time to take off and clear an obstacle, the  engine will be shut down. Finally, emergency proce- dures should be discussed. At a minimum, it should  be explained that in the case of a rollover, the pas- senger should keep arms and legs inside the protected  areas of the cart. In case of an accident, the passen- ger should not be holding onto a part of the structure  that could hit the ground or an obstacle and hurt their  hand or any other part of their body. The informed  passenger is a safe passenger and one that will enjoy  the flight. After entering the cart, you should first ensure that  all necessary equipment, documents, checklists, and  navigation charts appropriate for the flight are on  board and secure. If a portable intercom, headsets, or  a hand-held global positioning system (GPS) is used,  the pilot is responsible for ensuring that the routing of  wires and cables does not interfere with the motion  or the operation of any control. Regardless of what  materials will be used, they should be neatly arranged  and organized in a manner that makes them readily  available. Loose items should be properly secured to  ensure nothing goes through the propeller or departs  the aircraft. All pilots should form the habit of good  housekeeping. With the wing spread out in the inverted configuration  and the lines inspected, you can pull the cart forward  to tighten all of the lines. This will begin the stacking  process. When the slack has been removed from all  lines, the pilot then goes back to the wing and finishes  the stacking process by hand. This usually means tak- ing the trailing edge of the wing and tucking it under  the rest of the wing. To complete the process of stacking the wing there are  two options for laying out the leading edge. Generally,  if there is no wind you may want to leave the leading  edge open on top of the stack. If it is a little windy,  take the leading edge and tuck it behind and under the  rest of the wing. By “hiding” the leading edge over  and under the rest of the wing, the wind will blow  over the top of the stacked wing without catching the  open edges of the wing cells. When you start the take- off roll, the leading edge is pulled forward and up, is  exposed to airflow and begins a quick inflation. The stacked method of laying out a wing involves  piling the wing up like an accordion with all of the  suspension lines stretched out as far as possible to the  rear of the cart. [Figure 7-2] The pilot can choose to  change from the inverted layout to the stacked method  on days where a slight wind is blowing or if the pilot  is concerned with the condition of the takeoff area.  Pavement or areas of the ground not covered in grass  in the takeoff runway will make it necessary to get  the wing off the ground with as little ground drag as  possible to avoid tearing or jeopardizing the integrity  of the wing fabric and/or lines.  When you are comfortably seated, fasten the safety  belt and shoulder harness and adjust to a comfortably  snug fit. The shoulder harness must be worn at least  for the takeoff and landing, although because of the  open cockpit, it is highly recommended both pilot and  passenger wear seat belts at all times. If the seats are  adjustable, it is important to ensure the seat is locked  in position. Accidents have occurred as the result of  seat movement during acceleration or pitch attitude  changes during takeoffs or landings. When the seat  The FAAregulations require the pilot to brief each per- son on board on how to fasten and unfasten his or her  seatbelt and, if installed, shoulder harness.
