The TAWS deadline in your country is rapidly approaching.  The good news is Avtech’s DSU offers you an installation that saves time and money by using the one that is already there.  You don’t have to replace your current display or radar system.  Avtech’s Display Switching Unit (DSU) displays EGPWS or T2CAS information on Honeywell or Collins Weather Radar Indicators.  The DSU switches up to three sources of display information and also facilitates overlays such as TCAS, Storm Scope, and Data/Navigation.  The DSU saves the cost of a new display and also greatly simplifies the installation.
