Hi,

getting more and more intrigued by your products given the new updates, so I am doing a bit more research on how I could install an EMS, likely a D180, on my Pipistrel Virus.

I will surely have a bunch of questions in the next few days, but let me start with one regarding the flap position indicator.

I have read the EMS documentation, and it clearly says that calibration should be started from 0 degrees flaps going down to full flaps, with a minimum of 2 points and a maximum of 5. I take that you do a linear interpolation for the intermediate flap positions, corrected if you have more than just 2 readings.

But what about cases like mine, where the all-composite flaperons on my machine also come with a negative flap position, to be used in cruise?

My flap settings thus are -5 degrees, 0, 9 and 18. Just 4 positions with a latch at every one, but with one which is negative. How does the EMS cope with a case like this?

Also, would it not be nice to have V-speed alerts at certain flap settings? My machine must have negative flaps above 70 knots, and it would be nice to have the EMS scream at me should I forget to put them in the negative setting (the alert could be something like "check flaps").

Thanks and ciao, Luca

Negative flaps will not be in this release. Negative flap support is on our list now for a future release though.

You can use the EMS with the current flap setup now if you really want to- you can make your negative flaps 0 degrees, your zero degrees 1 degree, and then correct after that.

Not sure when/if we'll do flaps vs. airspeed alarms. This is a lot more integration, since it needs to check EFIS vs. EMS data.
