Just to be clear, the planes DO have an intercom, but you have to push the button to use it. Thats hard for a CPT do to on the ground when both hands are occupied. In the air? If / when you want to talk, I probably wont hear you unless you yell or use the intercom. Headset goes over both hears as soon as I let go of the tiller.. If I don't do that, I will never hear you.. Much worse !
