Southwest Airlines will begin upgrading the computer software on two thirds of its jets to use GPS technology during landings. Alaska airlines already uses it.

ABC7'S aviation consultant Ron Wilson explains how the technology beings working about one-hundred miles away from the end of the runway.

"Bring the throttles back on the airplane and glide all the way into the airport without touching the throttles of the airplane. That is a real fuel saver, it's a quiet approach for the neighbors below, it is a very smooth approach for the passengers and that is the ideal approach," he said.

Wilson also points out this will reduce delays for jets equipped with GPS landing capabilities, but it might increase delays for those which aren't.
