At least, that’s what we saw both in flight and at bench demonstrations. Except for the victor airways, you are speaking letter-for-letter what you would twist and enter in the normal flight plan page-but even spelling them out is much, much faster than twisting.īecause this is a very limited set of words the VFS101 must know, the character recognition accuracy is virtually 100 percent with no voice training required. The VFS100 beeps for every recognized waypoint, but you don’t need to stop speaking so long as you keep holding down the VAS button. Assuming there is no active flight plan, you can start a new one by pushing and holding the VAS and reading off the clearance phonetically: “Kilo Papa Whiskey Mike ENTER Echo November Echo ENTER Victor Two Seven Zero ENTER …” and so on. The way it works is there’s a button on the pilot-side yoke called the VoiceFlight Activation Switch (VAS). The VFS101 will let you speak that clearance as is and do the decoding for you. That means pulling out a chart or asking some app like ForeFlight to decode it for you. Your clearance might come in as “KPWM ENE V93 CTR V270 ATHOS 1B1,” but a 430 needs all the waypoints that define those airways. The system’s biggest trick is entering flight plans. VoiceFlight does both for users of the Garmin GNS 430/530. For voice control to be worth the trouble it has to save you time or reduce your workload in a measurable way. That concept of a few, focused commands is important. However, the right combination of improvements in voice-recognition technology and a few focused voice-control commands make the VoiceFlight VFS101 system a success. Having your GPS misunderstand where you want to go would be something else entirely. When your iPhone turns “Call Bonnie Smith Home” into “Calling Ronnie Schmidt Home” before you stamp the “end call” button, that’s not such a big deal. It’s not that it can’t be done, it’s that there are inevitably errors. While almost every sci-fi epic has us navigating our way around the galaxy by voice command, the reality of controlling computers by voice has been a bit less impressive.
