Boeing said Wednesday it has delivered upgrades for three F-18 Weapons Tactics and Situational Awareness Training Systems (WTSAT) to the Finnish air force. The airframer said the aircrew trainers offer the capability to train for aerial refueling and provide a long-haul networking capability that allows the systems to link over a Wide Area Network.The WTSAT features a simulated head-up display, three Debrief Stations (DBS), an upgraded flight program simulation, and enhanced Instructor-Operator Station capabilities. This delivery also included upgrades for three Deployable Tactics Trainers (DTTs) delivered in December 2007, which integrate a supplier’s visual system with Boeing hardware and software. A single software baseline runs in all three devices, Boeing said.
