how does anti-icing on airplane cockpit's windows works?

Question

i mean how does they prevent the cockpit's windows from icing

I know its a long story and here nobody has the time to explain all the procedures
but if u know any place or article i can find information of this, pls help me
i couldnt dig any information about this specific information on net
thanks

Answer 1

Anti-icing on cockpit windshield can be done several ways -

The most common is electrical heat as part of the windshield -

Electrical heat also improves strike resistance of the windshields -

Some airplanes use hot bleed air (see the scoops on DC8 or Learjet) -

Do you ever realize that teenagers have no sense of humour -

They want to be taken seriously as (almost) adults -

Do not joke with teens who hope to grow a mustache soon -

Most of these FSX pilots will be A380 captains soon...!

I only know the 737 Next Gen and it's fully automatic computer controlled. All you have to do is flip the switch. Only the #1 and #2 windows have it. Nothing on #3 windows. The system can only prevent ice, not melt accumulated ice. The system cycles electrical current through the windows. There is a special layer of material bonded into the windows to work in conjunction with the system. Just keeps the window surface temp warm enough to prevent ice from forming.

How technical should the answer be?

Windshields and side windows are electrically heated (talking about a specific type) for the purposes of anti-icing (with the help of dual phase current) and defogging (if that isn't obvious). Windshields are usually deiced, sliding and fixed windows demisted. Each window contains multiple sensors and a heater. Heating can be operated automatically or manually. When operating automatically, heating comes on when at least one engine is running or the aircraft is in flight. Manually, with engines off, flight crew can also select it if necessary. Heating operates at low power on the ground and at normal power in flight but there is only one heating level. The system is automatically regulated by two independent computers, brilliantly named Window Heat Computers. WHC's task is heat temperature regulation (32°C - 45°C), overheat & overpower protection and fault indication.

There you go, window heating system of a modern jet demystified. Would that be all?

Answer 4

Pitot tube freezing delivered approximately the autopilot disengaging. however, the tubes cleared of ice nicely till now the airplane certainly crashed; there grow to be quite some time to get well. With the instruments indicating a speedy loss of altitude the copilot pulled on the stick. The plane zoomed up a number of thousand feet, and definitely climbed out of the clouds. At that ingredient the pitot tube icing cleared and the instruments have been showing the perfect records yet by potential of that ingredient the group had lost all situational expertise. The copilot persevered to drag on the stick inspite of the stick shaker. At one ingredient the airspeed dropped to under seventy knots. by potential of then, the stick shaker stopped because of the fact the flight records pc grow to be in no way programmed for those sluggish airspeeds; in effect it thought that the airplane grow to be parked on the floor on a solid windy day. the priority grow to be while the pilots tried recover from the stall they saved hitting the stick-shaker persistently. They in no way found out that they saved accelerating into the stall waring as a substitute of slowing down into it, as is often the case. it variety of feels that they in no way found out how deeply they stalled the plane.

Answer 5

Its either hot air or electricity, in most airplanes that is.

Answer 6

1) There are various methods of windshield heating, including electrical heating elements, hot bleed air from turbine engines, and alcohol or glycol-based de-icing fluid. It depends on the particular type of aircraft. some do not have it at all.



2) It's "How does it work?", not "How does it works?". Singular form. Basic English 101.
