This may sound "old school" for the age of the portable device, But I wish there was a way to make your flight plan, with all the info you could need, on your computer and either sync it directly with a tablet/phone or with an on-line account that that can then be synced in the same way. Similar how to you can store Google Maps offline on Android.
Then, when you're in the map display, go into the options and tick the box labeled "use only downloaded charts" which will prevent it from downloading more on the fly.
For things like approach plates and airport diagrams, if you didn't download the entire quadrant you can download individual pages in the Airports section by clicking on them while you're on WiFi, it will save them for future use until they expire.
I have a Dual electronic GPS160 parred with my ipad mini using FltPlan GO app and love it. I do my VFR flight planning on SkyVector.com then input way points into Fltplan app, sync GPS and fly away. All backed up with paper charts. Uses no Data, other then Internet wifi, where ever that may be.
Edited to add: The Nexus tablets from Google also have dual GPS/GLONASS receivers, so they can lock using both the US and Russian satellites. Some other android tablets have this as well, I don't know if Apple included the GLONASS capable receiver or not.
-A-GPS chipsets in many tables and phones are optimized to use the wifi/cell signal for faster cold fix, but take a really long time to get a GPS cold fix when you're away from cell/wifi coverage. I have seen this on my devices when removing my sim card for international travel. Without WiFi in range it sometimes went 45 min or more without getting a fix, despite a wide open sky.
-Many external GPS chipsets will have better accuracy and faster update rate. My cheap Holux bluetooth gps that I got years ago has 32 GPS channels (which helps track and eliminate some multipath errors), and a WAAS/EGNOS decoder, which results in a ~2m accuracy and less than a minute to cold start.
-Battery consumption while using a bluetooth or wired GPS receiver will be better on many devices compared to using the on-board GPS. This varies from device to device, and of course your external GPS will need to have it's own batteries charged, but the one I have lasts a lot longer on a single charge compared to my phone with GPS enabled.

Its a complete cockpit to AMO system... best part, is no more paper!
Program is called Propeller One, I'll include a video below and the contact info for the person we deal with
I do notice that if you have no internet access, FltPlan Go will sometimes hang for 30 seconds when you click on the CFS link for an airport (even if you've already downloaded the CFS). It eventually appears, but is quite annoying if you're actually flying and trying to bring up the airport info!
Alternative: Turn on airplane mode when flying. Data and phone are turned off, GPS remains. Then all of the content is pulled from what you've already downloaded, and (bonus) no ads!CpnCrunch wrote:Unfortunately on Android there is no way to restrict foreground mobile data, only background data. Even if you've downloaded everything and turned off all the layers like weather and TFRs, FltPlan Go still uses a lot of data displaying adverts and making requests to the website. I'm pretty sure it's a bug, as it seems to be constantly making unnecessary web requests. I pestered them about it a while ago, but gave up when they didn't seem to really care. Perhaps they've fixed it since then, but I mostly just use a tablet which doesn't have mobile data which solves the issue.

Ah, right. How effective is that, given cell coverage is only really useful near built-up areas where you don't really need tracking?CpnCrunch wrote:I use mobile data for tracking.
I've found that I have cell coverage over pretty much all lower mainland, Vancouver Island, and most of the major valleys in the interior. The benefit is:AirFrame wrote: Ah, right.

 If I get knocked out during a forced landing, someone will know roughly where I am
 If I do a forced landing, say, in the middle of Vancouver Island en-route to Tofino, there might not be any cell reception where I land, but there probably was 5 mins about when I was at 5000ft.
The only thing is that if I put my phone in my pocket, the tracking stops (I assume it can't get GPS reception). If it's on my lap, it works fine.
Good to know, thanks. I flew to Calgary from Langley once and had my phone velcroed to the instrument panel so I could use AirNavPro on the way (this was before FltPlanGo became popular). Every time I looked at the phone I had cell coverage, with data (although sometimes Edge network only). I was mostly following highways though, so "sparsely settled" would describe it.CpnCrunch wrote:I've found that I have cell coverage over pretty much all lower mainland, Vancouver Island, and most of the major valleys in the interior.
On a more recent flight to Springhouse Airpark, pretty much direct from Langley, I lost cell and data regularly along the way. That's when I was happy to have my SPOT.
