What is grounding therapy?
Grounding, also called earthing, is a therapeutic technique that involves doing activities that “ground” or electrically reconnect you to the earth. This practice relies on earthing science and grounding physics to explain how electrical charges from the earth can have positive effects on your body.
What are the key benefits of grounding in aviation?
It helps to reduce emissions, fuel costs and noise pollution around the airports while the aircraft are circling the runway. From a student perspective, it is also the most efficient way to learn.
