New user trying to learn what is and isn't available.  Two things I've been looking for but so far haven't been able to find:

  1. I've found the hi-res winds aloft that can be shown on the map that displays wind barbs at different altitudes.  Is there a way to get the actual (textual) wind speed and direction values at a barb location/altitude?  Something like the functionality of this page would be great:  https://www.markschulze.net/winds/
  2. I see that the flight planning takes winds aloft into account.  Is there a way to extract/display the desired true heading for a leg of the flight plan based on the winds aloft (or even better, the magnetic heading that factors in both winds aloft and magnetic variation)?

Thanks,

Andy

1. No, you can either click map mode/hi res winds to view the wind barbs. Alternatively, you can open your flight plan, click "altitude planning" and see the wind barbs along your route stacked at different altitudes.

2. You can toggle true or magnetic heading under menu/setup/units of measure/compass to see true and mag heading

Welcome aboard, and let me know if you have any more questions.

Thanks.  I had noticed the wind barbs in the "altitude planning" screen, but wasn't exactly sure how to interpret them.  When in that view, are they indicating just the headwind/tailwind component along the path of travel, or the total windspeed (but without any direction indication?).

I get wind speed and direction from my Dynon D10 and it is one of the most valuable features. I find it amazing how quickly the winds change when I fly cross country. Sometimes the difference can change from a tail wind to a head wind in a couple miles. It even shows how much of the wind is crosswind component. I wouldn't be without it. 

IFLY doesn't provide it, but you can get a pretty good estimation by comparing your heading and track to determine direction and then compare your TAS with your ground speed to get the wind speed. Of course, you could have winds from your 3 or 9 o clock position and not see a significant difference between TAS and ground speed, but comaring you heading and ground track you'll still know the direction.

OccasionallyI use the method above to check the accuracy of my Dynon indication.

Anolther useful feature is active glide ratio. I've asked Dynon to see if they can provide glide ratio while I wait to see if IFLY can/will do it.

As a new user you will find many useful features in IFLY and this forum is a good source for any questions you may have to get the most use from the app.
