The Windows Phone app Vectorial Map uses offline vector maps. It is also available for iPhone, Android and Blackberry. It uses OpenStreetMap maps in the Mapsforge format, which you can download for free.
I used to run such a tool during the Tohoku earthquake and got tens of thousands of people reporting their status. My experience is that such a tool is difficult to maintain and support, especially during busy times and amid electricity power cuts. So even though I am usually in favour of self-hosted solutions, here it makes more sense to rely on a solid ...
For a hopefully suitable Android app, I've checked with my app search by permission for a task app requesting the RECORD_AUDIO permission, indicating it should have voice support. That yielded 10 apps, which I checked, and here are some at least partly matching your requirements:

This app offers a widget for voice-to-text to add a ...
No, there is currently no such app. The only solution is to open your web browser and use Anki's web interface called AnkiWeb:
Beware, several Windows Phone apps with "anki" in their names are getting money from unsuspecting users but are actually not compatible with Anki. Example:

Microsoft do supply a free community edition of Visual Studio here
Will guess how to convert from Android OS to Windows It is from Microsoft so I very much doubt it.

There is a app called "tasker" which can switch your phones into airplane mode.
You only have to decide how to trigger it. You make it time triggered.
Or triggered by a android intent. Or when a special email arrives in the K9 mail client. Or you could use notifymyandroid.com to trigger it in tasker.
Or you could do it by a SMS. Many possibilities.
There is certainly a collection of apps you can use for this. One of the keywords to check is Geo-Fencing here, available with a bunch of e.g. "child protection" apps (see: Location Monitoring): you define the area your "child" (here: car) is permitted to be in, and as soon as it leaves that area (your car moves) an alert is triggered. Examples here are GPS ...
