I was having a discussion about replacing the VSI steam gauge with the D6, since the D6 has a VSI display. Could you share with us what the minimum altitude resolution of the D6 is, and what is the sampling period that the altitude trend is sampled over?
I was saying that if, for instance, the D6 has a 10 foot resolution and it samples over 6 seconds, the minimum resolution in feet per minute would be 100 fpm, since 10 feet altitude change in 6 seconds is 100 feet in one minute. If you sampled for a shorter period like 3 seconds, the resolution would be degraded since a 10 foot change in 3 seconds would display as 200 fpm.
I was just interested to know if the D6 resolution matches that of a steam gauge, which I can read to about 100 feet per minute. That is about the pointer width of the steam gauge.
Does the VSI on the D6 use anything other than altitude from the static line and time from its internal clock? Does it try to integrate pitch information from its sensors into the equation?
Thanks for your willingness to share this information with us. We would have little luck getting this good stuff out of Garmin, Bendix, Chelton, L3, etc. with their "certified" units.
