My understanding is that both for FAA regulations and the sake of battery life, the Trakdot turns off when it senses a certain speed (in flight) and turns back on once you land and are no longer at speed.
My Trakdot works well and I'm fairly pleased with it. Here's a screenshot of Trakdot doing it's thing en route to AMM:
