Equipment Functioning

1-13 Equipment Functioning - Continued d. Transmitter/Controller (T/C)(4)-Continued The T/C can be carried by a parachutist while descending under a parachute and has the option of a remote control switch assembly (5) which plugs into the T/C. The remote control switch assembly terminates in two thumb operated switches which allow the parachutist to control an AGU in flight manually with a thumb switch in each hand such that he/she does not have to remove his/her hands from the parachute control handles to command with AGU. The T/C can be operated either in the manual mode or automatic mode while on the ground or in the air while being carried by a parachutist. In the auto mode, the AGU and T/C work together to fly the parachute to the target without any operator intervention. In the manual mode, the operator uses controls on the T/C for precise steering of the parachute during descent. The T/C may be switched between manual and automatic modes at any time. This allows automatic homing during the first part of the descent and manual operation once the parachute is within visual range. 1-25
