Dumb question:

Why can a pilot turn off the transponder on a large passenger jet?

In what circumstance would it be necessary to do that?

Why not make them stay on all the time, with no way to turn them off?

A transponder has several frequencies. Pilots are asked to squawk a specific channel to distinguish them one from another

What if in flight a malfunction occurred causing an electric fire?
You need the ability to turn off ALL the stuff in your aircraft.

Turning it off doesn't make its radar track disappear.
