Actually, an airplane does NOT have a horn like a car horn.
But, many DO have a horn in the cockpit. You will hear pilots talk about a stall warning horn, which is near the pilots seats. It sounds when the airplane is in a flight attitude that is conducive to a stalled condition. Some airplanes have a stall warning light instead of a horn, too.
