Garmin Aera 660 vs ifly 720

I read that Tom, but it seems it only displays what you are getting for a glide ratio not what you need to a fixed point. I do like the look and ease of ops with the aera 660. I talked with tech support for both units and niether will do what the 196 did, but Ifly is working on that in a next gen software. I also like the ipad/ foreflight that now has the amoeba for reachable glide. Its just alittle big in my limited cockpit space. In the mean time I found a used 196 for a 100 bucks on ebay

The VNAV feature is a glide to a waypoint.

True but it is given in fpm descent not glide ratio.

So what? Can't you do a simple conversion?

Sure, I can always go back to the whiz wheel too Isnt that the point of technology, not to have to do the conversions?

Not sure why not using one of the many flight computers available to us which do these calculations and so much more, some of them are even free?
I never used Garmin nor I ever felt the need for it.

I am using a SN10B, the garmin is a backup, with the added advantage of having the faa database with all of the info for airports in the united states.. As well as glide ratio to a point. I guess its just what Im used to and know how to use without a large learning curve. I have tried XC soar and use it on my phone as a logger when flying club ships but it is not intuittive and screen brightness on most devices(with the exception of Eink readers) is limiting.

My, my. Aren't we a bunch of techno-illiterates?

1 nm = 6076 ft
1 kt = 6076 ft/min

6072 ft/min
------ = 61:1 glide angle
100 ft/min

6072 ft/min
------ = 30.5:1 glide angle
200 ft/min

I bet you can do the rest - if you tried.

Err, no!

1kt is 6076 feet per hour or (for all practical purposes) 100 ft/min.
