Turn your Smartphone or Tablet (iPhone, iPad, Android, Windows Phone, etc) into a Cockpit Voice Recorder! Just plug the 3.5mm (4 conductor) plug into the headset jack on your Smartphone, and your aviation headset into the adapter and you'll be able to record all audio heard through your headset.
Your Smartphone will be able to record all transmissions through the Intercom systems including in-cabin and ATC transmissions. Great for CFI's and Students to review radio communication skills after the flight! Or, use the video recorder in your Smartphone to video tape your flight and record the audio from the intercom as well!
