Q: Where is this made? Is the unit suitable for small GA aircraft? How often do you need to calibrate the unit and does it have to be done by the factory?

This is made in the USA. Per the manufacturer, "It does not need to be calibrated. The unit shouldn't drift more than 5-10% over the span of 5 years so it will remain very accurate. It is meant for personal monitoring so while technically it could monitor an unlimited amount of square footage, it really should be worn or placed in critical measurement areas to make sure it is protecting the airspace around the users."
