From the cockpit, I want to transfer my flight log to my phone and email it to the contest scorer.

If your IGC approved logger is Bluetooth equipped and it is paired to your phone, is it just a simple matter of downloading log to phone and emailing the file?

Are there any "security" issues or 3rd party apps required?

Thanks for your input.

Shouldn't be any problem. The security is built into the file contents, and is thus carried along when you email it.

In the recent Region One contest I wanted to configure the IGCdroid app - which already runs on my phone, and was my backup logger as well as providing real-time tracking - to automatically email the log file to the scorer directly. Meeting some reluctance on the part of the management, I only had it email it to myself. Then I forwarded that email to the scorer. Turns out the log file *name* was not acceptable to Winscore (fixed that by renaming it manually). The naming issue has since been fixed in the app, so be sure to get version 1.19 (or later) if you plan to do that.
