in a typical haho exercise, the jumper will jump from the aircraft and deploy the parachute at a high altitude, 10–15 seconds after the jump (typically at or so). the jumper will use a compass or gps device for guidance while flying for 30 or more miles (48+ kilometres). the jumper must use way points and terrain features to navigate to their desired landing zone, and correct their course to account for changes in wind speed and direction. if deploying as a team, the team will form up in a stack while airborne with their parachutes. usually, the jumper in the lowest position will set the travel course and act as a guide for the other team members.
