The center floater must move during the exit count to let the front and rear floaters key in on the exit timing. Make sure everyone can see or feel the exit motions. Timing is the key to successful exits. Have someone who wants to spot, spot. Avoid yelling and screaming on the aircraft.
Some formations are easy to launch because everyone is naturally presented into the relative wind.
Other exits funnel because of poor timing. Ensure that everyone is in step with your key exit person. Chunk exits can be slightly more dangerous than other types of exits. Gear can get rubbed against door jams, struts and other jumpers. Tight chunk exits have been known for zapping people or giving them floaters and other assorted malfunctions.
