Question:
i mean the horns which i think every transport medium in the world have it.but never heard from the aircrafts?!!
Answers:
Can an aerospace /aviation engineer work in an airport?
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.what kind of non destructive testing can be done on aircraft tyres to detect internal cracks?
Depends on the aircraft.If you think on it real hard , do you think you would hear any horn beeped at you over the sound of the engines on a plane , and were would you use it, to warn pedestrians? to avoid a mid air collision?if you think on it ,it is a bloody silly question isn't it.
travel delays for NWairlines today?
No! LOL what are they going to honk at the birds.actually aircraft's most of them have horns they mostly use them to taxi around the airport
are co-axial rotor helicopters still built and used anymore?
Horn as in "Beep Beep"?No.
Aircraft are too fast for a horn to be of any practical use.
What is a good company that will charter LARGE jets?
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.http://www.jims-pages.com/foison/images/...
Aircraft will get attention with strobe lights -anti collesion lights
landing gear lights& screaming Engs. about 150 deciables.
Where can I find out how much is the salary of a pilot in different airlines ?
A Horn would be too late.
why did the flying tigers paint a shark on their plane?
In WW2, the Stuka dive bomber had sirens........No.
What if I need to cancel my flight?
No, but the pilot can rev up the engines, flash some lights, or talk in the radio.reserve seats during check-in or upon payment of tickets?
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.Any pilots know how long the conversion course is from Boeing 737-300/400/500 to the NG?
No they dont have horns but use their lights as a method of signals.how do i read an instrument approach plate?
Commerical aircraft have horns BUT...Are there any colleges in the UK which offer Aeronautical Science degrees aswell as flight training?
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.
the ranking of "Hindustan Aeronautics Limited" in aviation industries?
• 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)
who offers Anti Ice Protection for business aircraft?
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 ;)
