A Purdue University-developed product called Blueavion f1, launched Monday (July 23) by Bluemac Analytics Inc. is shown to help airports more accurately log airport operations. While Purdue University Airport is the second busiest airport in the state of Indiana and open 24 hours a day, Lafayette Air Traffic Control Tower operates only during the busiest hours, a common situation found at many towers. Technology can help the airport more accurately log its flight operations, according to Adam Baxmeyer, manager of Purdue University Airport. Which is one reason why the Purdue University Airport participated in the testing of the Blueavion innovation.

"Our control tower is open 14 hours a day, so that means we have 10 hours a day where we have to find other means to capture operations data," Baxmeyer said. "We have been able to advance our data collection through this new technology and capture data we might otherwise miss."
