Do aircrafts have Horns?

Question

i mean the horns which i think every transport medium in the world have it.but never heard from the aircrafts?!!

Answer 1

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.

Answer 2

Okay, We've established that aircraft are loud. Some are loud in the cockpit, which is why many headsets for light aircraft are sound insulated so that the pilot can hear what the person on the other end of the radio is saying to him. Jets, typically, are more sound attenuated, so that engine noise isn't a factor inside the cabin. Aircraft, on the roll, in either controlled or uncontrolled ground operation areas, are operated by highly trained personell, or highly trained instructors. On ramp areas, where pilots are most likely to taxi their airplanes into another airplane, at busier airports, it's common to have line personel guiding them. Last, but not least, if a collision is imminent, it's between a moving aircraft and a non-moving aircraft. It'd be like a ship sounding a horn at the lighthouse it was about to collide with. If the maritime anology doesn't get you, try driving towards a brick wall. Honk at it and see if it in any way exhibits behavior beyond sitting there inertly. Should you be willing to try either of the anologies I've provided, would you be so kind as to let me know who you're insured with? I'd like to make sure I don't have any stock in the company before you try.

Answer 3

Actually yes, some do. There was a time when there was an interest in a small plane that converted into a car once you landed, and of course it was equipped with a horn. They used the horn as the stall indicator while it was in flight, so it landed with the horn blaring.

Answer 4

Some are equipped with a ground crew alert horn, only of use around the aircraft when parked. Last time I used one it was on a JT8 powered Boeing 737, so it was a while ago.

Answer 5

Commerical aircraft have horns BUT...

One horn outside the aircraft is to get the attention of ramp personnel.
In the cockpit-

• cabin altitude warning horn when the cabin altitude is above 10,000 ft.

• takeoff warning horn, when aircraft is not properly configured for takeoff.
(PS commerical airliners do not use a stall warning horn but use a stick-shaker)

Answer 6

Do Airplanes Have Horns

Answer 7

If your talking about audio horns in aircraft... No...

But you can see rather large bull horns straped on the front of aircraft from time to time flying out of Texas ;)

Answer 8

Aircraft will get attention with strobe lights -anti collesion lights
landing gear lights& screaming Engs. about 150 deciables.

A Horn would be too late.

Answer 9

No they dont have horns but use their lights as a method of signals.

Answer 10

Horn as in "Beep Beep"?
No.
Aircraft are too fast for a horn to be of any practical use.
