Every month I update the data on my apps on my iPads. Since I fly with two iPads it takes a while. I thought I would time it today to see how long each app took to update. To the best of my knowledge I have about the same areas and the same information chosen to download on each app (western US, VFR, IFR & Jet). My Internet connection isn't the fastest. They took: Wing X Pro 87 minutes FltPlan Go 26 minutes AeroVie 15 minutes Fly Q 3 minutes Avidyne 2 minutes

I have a couple of questions for anyone that has Skyradar and use it with WingX. I just got the Skyradar DX Dual band receiver with the AHRS. I am using it for backup weather, traffic and attitude indicator. I already have an MX-20 with a GNS 480 and I get traffic and XM weather on those instruments. I used the Skyradar for the first time today and it appeared to work very well for traffic, weather and with the AHRS. I compared it to my current, attitude, traffic and weather on the MX-20 and 480 and it was pretty much the same except for a few minor differences and that was my question. I noticed that the traffic was a little different between what I saw on WingX, what I saw on the Radenna Skyradar software and what I saw on my MX-20.. Not a lot of difference but there was some. Does anyone know what causes that? Is there a distinction as to how the programs pick up the dual ADS traffic bands and then display them in WingX and the Radenna Skyradar software? As I was flying and using the Skyradar with the WingX it showed an aircraft at my position and altitude that did not show up on my mx-20. I made a turn to check for traffic and noticed that the WingX traffic icon turned with me. That's when I figured out that WingX was showing my plane as the traffic in addition to the WingX icon showing my position. Has anyone had this happen to them? Why would WingX show my plane as traffic on the ADS-B traffic system? I have a GTX-330 transponder with mode S installed. In addition to supplying TIS traffic to my mx-20, 480 and 430, I read in my manual that it transmits a coded response at 1090 MHz, the same frequency that is picked up by the Skyradar receiver. Is it possible I am receiving ABS-B traffic of my plane sent back from the ground stations because of the signal sent out by the GTX 330? On another note, does anyone know what happens when you turn on the "Filter ADS-B Traffic" in the settings section of WingX? Does it filter out the traffic or filter out traffic at certain distances. Thanks.
