Do Aeroplanes have windscreen wipers?
Windshield wipers are the most common rain protection feature. Most of them use electrical motors but some aircraft may be equipped with hydraulic wiper motors. In general, the wipers are used during ground operations, for takeoff, during the final stages of the approach and for landing.
Why do some aircrafts have windshield wipers?
Windshield wipers, still in use even on the Boeing 747, are highly effective at sweeping rain and snow away from aircraft windshields, but with the higher speeds of jets, other innovative methods were employed to maintain good pilot visibility during approaches and departures in bad weather.
How do I know if I have automatic windshield wipers?
You can check if you have a rain sensor system in your car. First, if your wipers automatically turn on when raindrops come in contact with the windshield then you have a sensor. You can also check by looking from the outside – behind the rear view mirror.
Are there window wipers on a jet plane?
On a larger airplane, the additional piping, valves, etc. required to get the hot air all of the way up to the windshield actually weighs and costs more than just putting the windshield wipers up there along with electrically heated windshields to keep them from fogging up. In the EMB-145 we could use the wipers below 170 KIAS.
Are there windshield wipers on a Boeing 787?

The Learjet’s on the other hand DO have hot air that blows on the windshield and we sometimes used it to blow water droplets off of the windshield when on the ground. However, the primary purpose of the hot air was to heat and defog the windshield.
How are windshields kept clear on airliners?
Keeping airliner windshields clear today is a far cry from the early piston era when pans of alcohol mounted above the instrument panel were lit on fire to prevent windshield icing.
Why are there windshield wipers on jet aircraft?
Also, on some jet aircraft, the airflow over the windshield at approach speeds (read: high angles of attack) isn’t sufficient to clear the windscreen. These aircraft will have either windshield wipers or bleed air ducts to clear the windshield during the approach. Dec 12, 2012 1,392
