Ignition switch, what happen when Left or Right is selected
Hello,
Here is my question:
On regular aircrafts, like C150, C172, PA28, when we perform the
magneto check where we select Left, than Right, while looking for RPM
drop... what is the switch doing?
When we select Left or Right, do we short that particular magneto or
are we shorting the other one?
I checked all my books and cannot find the answer.
Thanks in advance,
Martin
