The NAV position is the normal operating position. The mode switch must be placed to NAv, and the computer must enter the NAV mode prior to moving the aircraft. If the aircraft is moved prior to entering the NAV mode, the computer will dump its program and the set will have to re-aligned. If the mode selector is place directly to NAV and present position inserted, the set will cycle through the standby and align modes and enter the NAV mode; however, placing the switch to NAV directly would be an abnormal procedure.
Automatic overheat protection is disabled in the NAV mode to prevent inadvertent shutdown in flight.
