VoiceFlight's VFS101 is an FAA certified speech recognition system that allows pilots to enter waypoints and airways into their GNS430W/530W GPS nits up to ten times faster than is possible using the tedious concentric knobs.  

VoiceFlight systems received an FAA Approved Model List (AML) Supplemental Type certificate (STC) for the VGS101, allowing it to be installed on almost all types of aircraft under 6,000 lbs. Maximum take off weight (MTOW).  With this approval the VFS101 may now be installed into hundreds of aircraft models without requiring installers to secure field approval for their local Flight Standards District Office (FSDO)
