...the voice process is too slow for a real threat. ...I think it takes a fraction of a second to take in with peripheral vision the clock face display indicating the direction of the threat, almost simultaneously scanning outside the cockpit. Right - Voice is not the fastest. It takes a while for the message, and it can get lost (for example if you're receiving a radio message). The fastest is a large simple graphical "pointer" in your field of vision, accompanied by a warning alarm. A visual presentation is less effective when: - its not already in your field of vision (turning head takes lots of time) - poor contrast - a complicated/busy/fussy display cannot be comprehended instantaneously - buried low on the panel Voice helps in the above situations... Here's the SN10 presentation (4 O'clock high): http://www.nadler.com/sn10/FLARMcol.png We also changed the Butterfly presentation from the original to make comprehension instantaneous... Hope that helps frame the problem! Best Regards, Dave PS: We built many voice applications (phone), some quite notorious ;-) Time for user to comprehend and use is always an issue. Think about various annoying automated phone services you've used. |

The problem is also how the voice function is implemented in the LX. The TR-DVS is much faster and very optimized to its only purpose, and it's decision when to alarm the pilot is much more reliable. However as always there are probably different opinions...
