Is there a way for iFly to filter the lowest NEXRAD returns in the data stream?

The top screen shot shows a typical sunny day in Phoenix. For some reason, there's always some returns to the SE of Phoenix, even tho there may only be a few clouds in the sky. (I don't think it's ground clutter because it changes. Although if you go on the web and look at a NEXRAD here, they typically have it set low and get tons of clutter. (The antenna is based as KIWA, which is to the SE of Phoenix, where all the green dots are showing.))

But the NWS RADAR (from an Android App called "Radar Express," is clear. That's the picture I'd rather have.

IIRC, this was a gripe of mine with Garmin Pilot - its RADAR presentation was too senstive - painting green when there wasn't anything to worry about. I learned to just worry about yellow with Garmin. But I would rather not have to second guess iFly.

(And lightning is coming soon, right? :-) )

Hi Shane:

There's something I'm mising - which is okay - you guys are the experts.

But you said "Keep in mind many of the web based sites use massive amounts of processing and algorithms that would not be conducive to a portable GPS device"

It seems to me that all the massive amounts of processing and algorithms of RADAR data would be on the Server end and consequently, you would be sending the portables less bits. That is, the unit is just a dumb terminal, painting what you send it.

What am I missing here? The guy who wrote the Radar Express app for Android isn't doing any heavy processing in the app. I'm guessing his data comes clean from the National Weather Service NOAA. (Per credit in the app.) It's a free app, so it doesn't appear that he is paying for the data. And it seems like good data. I routinely compare it to TV weather, Intellicast, etc and it paints cells where they are.

Mike,

There are two different scenarios. Serving up improved weather from the server side when connected to the internet is not the issue. It's the live ADS-B weather that is coming directly from a airborne receiver, that has no access to server side processing. In this event you'd have beautiful wifi internet downloaded weather radar and very simple basic ADSB radar, leaving the pilot with radar inconsistency. We try our best to keep consistency with visuals and data. With most enroute weather coming from ADS-B, we'd really like to find a solution to improve both radar aspects maintaining a level of consistency. .

I believe there is definitely room for improvement in the Internet downloaded weather radar. I've worked with Baron and other premium weather radar providers and due to high costs, those have stalled temporarily. We'll continue to improve our weather, please stay tuned.

Is it legal to operate a cellular connected device in flight in the US?

The FAA doesn't specifically prohibit the use of any electronics in GA aircraft; only to state that under 14 CFR §91.21, those aboard an IFR aircraft cannot operate electronic devices unless they are: Portable voice recorders, Hearing aids, Heart pacemakers, Electric shavers; or any other portable electronic device that the operator of the aircraft has determined will not cause interference with the navigation or communication system of the aircraft on which it is to be used.
The FCC, however, does ban the use of cellular phones in flight per 47 CFR §22.925: “The use of cellular telephones while this aircraft is airborne is prohibited by FCC rules, and the violation of this rule could result in suspension of service and/or a fine. The use of cellular telephones while this aircraft is on the ground is subject to FAA regulations.”
It was recently proposed to relax this, but I've not seen any further developments. Is that clear as mud?
