description abstract	Description of Driving Event: Task leader started hoisting operation with a "slow micro" command to take up sling slack until 337 lbs was obtained. A joystick controls hoist movement which may be controlled at a low rate, but only by operator judgement. A switch energizes the hoist motor and disengages the brakes when depressed. If the joystick is in the null position when the button is depressed, load movement will occur with speed dependent on stick position when the brake is released. An overload at 900 lbs in the IPS resulted when "slow micro" was requested and the brake button was depressed with the joystick not in the null position.
