Help Airplane mode, Cell towers, and Pings

Due to work regulations I am now mandated to have my phone off. The primary reason for me wanting to keep it on is a trivial one so I've been rule compliant and kept it off at work. I like to use my newly acquired DX as a glorified watch and speedometer.

My question is this. If I put my DX in airplane mode, would it still ping cell towers? That is to say would my phone still send out information to data networks in such away to identify it as being on. Because the speedometer feature is a GPS feature I know airplane mode kills it. But, I'm not sure if inquiring minds could still tell my phone was on if I put it in airplane mode. I'd still like to use it as a glorified watch if possible.

Because of the nature of my work (passenger rail), I can't always be with the man controlling the train. So, I sometimes would use my phone to check the speed at which the train was moving as well as using the watch feature to approximate arrival times etc.

I've been told that one way this regulation would be enforced is by having phone records pulled and seeing if any calls were made / received and which towers were pinged as a person moves from point A to point B.

I've been reading about how some phones continually transmit information even when off, and I'm trying to figure out how the DX behaves. Is taking the battery out the only way to ensure this phone isn't pinging towers or is airplane mode enough?
 
Airplane mode turns off all radios, so I think you should be good here.

If you don't mind me asking, why do you have to have your phone off, and by what legal right would they pull your phone records without a warrant?

Every since that metrolink train accident in California the FRA has instituted electronic device bans. It's pretty much required that when I report to work I cut my cell phone off now.

As far as pulling records with or without a warrant. All of that is above my knowledge. I have only heard rumors and read railroading forums where any crew involved (directly or indirectly) in some mishap (i.e. hitting a car at a crossing, derailing, etc.) is subject to having their records pulled. There is also a rumor that much like the random drug tests we are subject to, there will be random cell phone record pulls. Could be false, but I choose to err on the side of caution.

Thanks for the reply!
 
Airplane mode does indeed shut off the cell radios completely so there will be no data transfer.

Since GPS is passive and does not transmit, it is not shut off when you turn the phone into airplane mode. You should still be able to track your speed using GPS only...

Hmm I just assumed it would disable the GPS. Thinking in terms of satellites and such. I forgot the DX can orient itself. I'll give it a whirl.

Yeah, GPS speedometers should still work, that is only receiving a signal, not transmitting anything. But you won't ping any towers or be able to receive anything, so unless you have maps loaded on internal memory, you won't have any maps to go with the GPS, but if all you want is speed, then that should work. Easy to test before work, too. Just kick your phone into Airplane mode and start the speed app, and see what happens.
 
I have the app GPS Status and it works great in airplane mode. I tested it yesterday before I posted. Speed and everything.
