Ignition switch settings

I'd rather have the toggles in my Jodel but it makes the
airplane so much easier to steal. If you can get in you can go.

You could rig up a cover to put over the toggles, with a place to put a
padlock on the cover, as long as it is not a certified plane.

Would altering a plane in that manner be against the rules for certified
planes? It would be in the certified plane's regular certified condition,
while it was being flown, after all!

And I've been trying to learn for years why R is on the left and L is on
the right.


My recollection from the last time this was discussed is that the labeles
used to be the other way around so that "L" on the left meant that the left
mag was grounded and, therefore, the right mag was firing. Then, to keep it
more consistent with the "Off" and "Both" labeling, they switched the
labeling but left the right key position which grounded the right mag so
that the left mag was firing now labeled "L"?

Doesn't bother me a bit. If one mag fails an RPM drop, I'm gonna check the
wiring to both any. What is more important to me is that the left key
position has the bottom plugs firing. That's important so that I can pull
the correct plugs the first time to clear an unusually stubborn fouling.

Say, why don't they label them "Off", "B", "T", and "Both"?

Excellent suggestion! Why not? It might make too much sense, that way!

One could put an "auxiliary label" on panel next to the "L" and "R" with a
Dyno Label, or with another favorite method, though.

I thought that one mag controlled the top plugs on one side and the bottom
on the other side.

Yup, on Lycoming. Continental, at least on the smaller engines,
will have the right mag firing the top plugs and the left firing the
bottom. The impulse mag (right) fires the top plugs, since they're
less likely to get wet with oil or fuel.

Cessna-style (and no doubt other) ignition switches have five
settings -- Off/Right/Left/Both/Start. When you're on the "Right"
setting, does it mean you are firing on the right magneto or
does it mean the right magneto is grounded?

Is this covered in the plane's POH?

Good question. It isn't. It isn't covered in the
shop manual either.
