Hi All I've found another bug in the datastream of my D100, running firmware version 5.4... Check out the timestamp and more specifically, the data frame id (in bold) in the following excerpt: In red is the change in time from 14:04:02 to 14:04:03, where the frame id doesn't go back 0. In...

Hi I have looked around a bit to find this, but haven't seen it anywhere, apart from the reference to "Larger servos will have a higher drag force"... What I would like to know is the relationship between the ratio between the maximum torque output of a servo (let's say the small one) and the...

Hi all Here we go for another funny yet serious request. I recently moved from 5400' to sea level, and with that has come an increase in available power in my aeroplane. So much so, that I now find myself easily reaching the yellow arc or segment on my ASI... Problem is that I am slightly...

Hi Dynon Just a quick question: Does the auto-correction of the QNH deactivate with an active airspeed? In other words, say you're flying an IFR approach and (as it happens in all those dark-and-stormy-night stories) your avionics breaker goes. By the time your EFIS boots up again you've...

Hi Noticed something funny in the Transponder serial output. The values are not bounded to -1200 to 31500'. If the pressure altitude drops below -1200' (highly unlikely, but none-the-less), the reported altitude sent to the transponder suddenly jumps to 31500'. I haven't been able to test it...

Hi Would it be possible to post a pic of a pre-release, subject to change, capstan servo? I'm a bit fuzzy on how this would actually connect to an existing cable set-up... How much movement will a capstan servo have at it's disposal? I'm guessing it would identical to the standard servos...

Hi At the moment, my EDC-10A is sitting in my aircraft, whilst I rebuild the panel at home. I have 4 instruments that all speak to each other, and I'd like to check that the D100 is part of the group of friends. It's running version 3 software (another question regarding that coming up). The...

The manual states I have a question... Adding up 49 values with a range of 0..255 will probably result in a fairly large number, in the range 0..12,495. Since there are only 2 hex characters representing the checksum in the feed, this equates to a checksum range of 0..255. So is the checksum...

Hi Fairly technical question... What voltage range is the PC interface using for the RS-232 comms? 0V to 5V, or 12V to -12V? Thanks Etienne

Hi all I've come across an error that occurred when using the older firmware, and I would just like to find out if it's a known bug before I go flying again... When turning left (i.e.e heading decreasing), as I cross 000, the heading increases, then jumps to the 350's... It's as if the...

Hi I have had an issue since the latest firmware update (the HSI one) where the altitude in the datastream flicks between pressure altitude (QNH 1013) and actual altitude (QNH 1031 in the example below)... 5 frames have pressure altitude and 5 frames have actual... When I change the QNH to...

Hi What data rates are supported for the GPS -> Efis link? Is it standard 9600 / 19200 or does the efis look for data rates all the way up to 115200? My GPS currently connects directly to a laptop, as does the efis. I'd rather do the 'wiring' in software, rather than have some complicated...

Hi all This is the cat amongst the pigeons... I'd like to find out if there's a need to create a version 2 of the datalog stream from the D-100, or the other efii :-) This poll is to find out what is used and wanted by those developing software that reads from the efis, and want to make use...

Hi A quick question on the airspeed output in the datalog stream: is it TAS or IAS? If it's IAS, is there any way to calculate the TAS using the the other data in the stream? Thanks Etienne South Africa

I'm not sure how pedantic this is, but to improve the look of the AH, how about implementing a shaded brown and blue look, as on Avidyne's EX5000 shown below: I think it look a lot more sophisticated, and since it's all about the user interface, I'd suggest it would greatly increase the...

Hi guys I recieved my AOA pitot the other day, and was surprised to see it doesn't have a static line. I would have thought that it would have been a standard feature of a hi-tec pitot (such as one that measures AOA)... Any comments? My aeroplane as it stands doesn't have a static port and I...
