Do aircrafts have Horns?
Yes and no. They don’t have horns as you are probably thinking of them, as in car, truck or train horns. However, all certified aircraft are equipped with a stall warning device (not engine stalls, but a warning indicating that the critical angle of attack for the wing is being approached, which, if exceeded, results in a stall, or loss of lift, due to separation of airflow over the upper surface of the wing) – some older aircraft use a stall warning light, but most aircraft have a stall warning horn inside the cockpit. In addition, larger aircraft often have warning horns and/or tones for various system failure modes – again, these are audible signals within the cockpit to alert the crew.
