This is an excerpt from a friend's letter to ForeFlight......
I've been using, (and learning about), Foreflight with a Stratus 1 receiver for a few months now. The flight planning and GPS features, including the positioning on IFR plates and taxi diagrams, are great. I remain, however, confused and disappointed with the weather and traffic features. I've already contacted you concerning the traffic feature. Although I didn't subscribe to Foreflight to get traffic, (most of my flights are IFR), it has recently been advertised that with the latest software and firmware downloads, some traffic would be displayed. Since the required downloads, I've flown on four flights in and out of a busy class B airport and have yet to see a single traffic blip!
I did, however, subscribe to get the weather product. Two days ago I was in IMC with precip in the area for the first time since using Foreflight/Stratus. I was very disappointed at the pixelated (block-type) display, and totally shocked by not being able to animate the cells. Rereading the Stratus description on Shorty's web site and the comparison between ADS-B and XM weather on yours, I was aware that there would be a slight difference in resolution (the difference is huge!) but can't find the lack of animation while in the air documented anywhere. This, to me, is a major over site AND a potential safety issue. Consider this please: I sat in my home during a rainy evening, getting used to my new software, and was totally impressed with the quality of the weather that was being displayed on my mini ipad AND the smooth animation ability. I was connected, of course to my home's Wi-Fi. I had no clue that while in the air I would get a completely different depiction of the weather and NOT be able to animate it. My real world situation the other day had a red square a few miles from my home airport that not only didn't move for a twenty minutes; I was UNABLE to to find the "play" button to animate it.
In an effort to understand this new technology better, is this a weakness in the Foreflight software or the Stratus hardware? If my lack of traffic and disappointing weather displays are not typical, could I be having trouble with my Stratus unit? Lastly, if this level of weather service is all that is being offered to date, what is the time frame for introducing improvements to raise your product to the level XM weather? (I cancelled my XM subscription based on the advertised descriptions of both Foreflight and Stratus but will have to subscribe again if this is all I can expect from Foreflight/Stratus)
