Narrative:

I am concerned about our MEL. It allows the cockpit intercom system to be deferred. The captain and first officer can't communicate with this system inoperative, yet the airplane is allowed to fly for 3 flight days under MEL 23-8 (BA4100). This situation needs to be corrected. This deferral waives the far for boom microphone use below FL180.
