AIT integration with logistic information systems is key to the Department of Defense’s TAV efforts. Also called AIT. See also total asset visibility. (JP 4-01.8)
A control mode in which the aircraft’s speed and flight path are automatically controlled for approach, flare-out, and landing. See also ground-controlled approach procedure.
