pressurize and raise the wing overhead making sure  proper inflation exists for takeoff, and to create the  airflow over the wing to generate the necessary lift.  [Figure 7-3] suddenly moves too close or too far away from the  controls, you may be unable to maintain control of the  powered parachute. The before takeoff check is the systematic procedure  for making a final check of the engine, controls, sys - tems, instruments, and avionics prior to flight. In ad dition, it gives the pilot an opportunity to establish a  go or no-go decision. The engine temperatures should  be rechecked, especially if any considerable amount  of time has passed since the engine warm-up was  completed, to make sure the engine and fluids are still  within the manufacturers’ recommended minimums.  If the air temperature is cold, the engine will cool  down faster than when the air temperature is warmer;  take a few minutes to bring the engine temperature  back up to minimums. Recheck the wind direction. If  the wind has changed, adjust your takeoff position so  you remain into the wind. Double check the steering  and suspension lines are not in the way of the forward  movement of the tires and the steering lines are not  tangled in the riser cables. Prime the engine, if so equipped, switch magnetos to  the ON position, recheck that the throttle is not open  beyond idle, and turn the electric master switch to the  ON position. Visually check the area, shout “CLEAR  PROP” and start the engine. Monitor the engine tem- peratures and check security of harnesses and hel- mets. Check that the strobe lights are ON, electric  fuel pump is ON (if applicable), oil pressure is within  limits (if applicable), and complete a final ignition  system check. Once again, the pilot has this opportunity to establish  a go or no-go decision point. Check the intended run- way and traffic pattern for existing traffic, and if radio  equipped and a nontowered airport, announce field,  type of aircraft, runway heading, and flight intentions;  if a tower-controlled airport, contact ground or tower  control to request a departure clearance. By adding  thrust smoothly to about half to three-quarter throttle,  the powered parachute will begin the takeoff roll. During the takeoff roll of an airplane, the goal is to  build sufficient airflow over the wing to generate the  lift required to lift the aircraft off the ground. Powered  parachutes have two goals during the takeoff roll: to  As the wing starts to rise off the ground and climb, it is  acting like a parachute with lots of drag; the cart does  not move forward much. As soon as the wing passes  through the 50° angle to the ground, the drag dramati- cally decreases as the parachute becomes a wing and  Make a final check to confirm that the cart is pointed  in the right direction and nothing has moved into the  way. Look over your shoulder to observe the canopy  inflation. Advance the throttle smoothly and firmly  to about one-half to two-thirds takeoff power. Too  abrupt an application of power may cause the cart to  yank the wing too roughly forward. This can damage  the riser system and shorten wing life. This is more  of a problem with higher horsepower engines than in  lower powered aircraft. As the cart starts to roll for- ward, make sure both feet are on the steering bars to  begin steering the parachute immediately. Figure 7-3. Pressurizing, or kiting, the wing.
