In this video I´ll be answering a great question which was sent in by one of my Instagram followers named KayDoc:"Dear Capitan Joe, do airplanes have windscreen wipers such as cars have them?" Fantastic question! Okay let´s imagine you´re sitting in your car, and as you get onto the motorway it starts pouring with rain. One little move with your finger and you´re windscreen wipers comes on, and you have a clear sight onto the road again. But how about airplanes, how do they get rid of the rain ?  On ground:   Put yourself into your passenger seat and imagine that we are slowly taxing towards the runway and it´s raining heavily. A passenger jet taxi´s (straight) with a speed at about 20 - 35 mph ( 30-60km/h ), which isn´t fast enough for the airstream to clear the windshields from raindrops. The visibility reduces dramatically which can be dangerous on airport aprons. So with one little hand movement, like in your car, every pilot can switch on his windscreen wiper. There is one wiper on each side which can be turned on separately and has two speed settings, slow and fast. During a rainy take-off roll we keep the wipers switched on, cause as you gain speed a lot of the water from the nose cone runs over the windshields and the visibility is reduced even more, so you have the option to increase the wiper speed . Similar as you go along the motorway at 60mph, you may use wiper speed „1“, but if you accelerate to 100mph, at the same amount of rain, you´re gonna have to adjust your wiper speed. Okay let´s imagine we´re in flight. During enroute cruise the wipers are inoperative. They are aerodynamically and mechanically limited to the speed of the aircraft so that the switches are inhibited. The limit varys between aircraft manufactures. The limiting speed for example on an Airbus A320 is 230kts (260mph/). On final approch ( approx 20 miles from the runway ) you fly at speeds of 260 mph, which is fast enough to clear the windshields from rain. But three miles prior to landing you will have reduced the speed down to 140kts and in heavy rain the wipers are absolutely essential to get clearly visibility onto the runway. In the event that one wiper is inoperative, may only the pilot with the functional wiper fly the aircraft. In the event that both wipers are inoperative, which is very unlikely, the aircraft is limited such as it may only take-off and land in visual metrological conditions and it´s capability to land within certain approach minimas (height and visibility) is reduced and limited.  Single engine airplanes don´t necessarily need wipers cause the propeller airstream is strong enough to clear the windshield of precipitation and most of them are only certified to fly in visual metrological conditions anyways. So the next time you´re sitting in an aeroplane and it´s pouring with rain , imagine the pilots doing this move:) I hope this short video gave you glance into the handling with windscreen wipers on airplanes! I hope you enjoyed this video. Make sure to subscribe my channel so you don´t miss future videos like these. All the best, your captain Joe Info: Many aircraft manufactors also installed a switch or a button which allows you to spray "rain repellant" onto the windscreen in heavy rain, smiliar to your wiper washer. Unfortunately this liquid was banned in many countries due to it´s highly chemical substances so that on most airplanes this switch is set inoperative. If you have a video of how to use the rain repellant, I would be very happy to see it.

Randy Black: Thanks! I saw a plane take out this morning in the rain and I had this question.

Minoosh: please use a clip on microphone to record the sound, the accoustic of your room is very bad!

thasindu himashaka: joe what is an airway or an air corridor

Anurag Dhadse: Captain Joe Can you tell me How an Airplane engine perform its work In rainy weather?

akshay gadhok: Captain joe .. hi could you advise difference between go around and discontinue approach .do we always do have to apply toga power if are below 1000 ft unstabilised ?

ScienceOfThePS3: If anyone's wondering, the background song is:

DevInvest: NO WAY Captain Joe deserves that janky L wiper!
Not even clearing the whole window!
No slackers on Captain Joe’s aircraft!
Get the man a new full wiper!

Navèn Patidar: Captain joe do pilots get holidays or can they go out when they are in the airport and the plane is parked

Adam's Plane butter Tips!: Bloop bloop,too low-too rain(i know that this is terrain)

TheThinkLess Jose: Dumb question. Can you rev the airplane? 😂😂

BluesyBor: Why not use Kent screen? You know, those circular windows known from ships (and some trains) which get rid of water by rotating quickly.
Yes, I know that aerodynamics are a major concern and getting a flat windshield (required for this device) poses some problems for an airplane, but come on - even if it's rocket science, we've been on the Moon decades ago. ;)

FalcoGer: i'm pretty sure they use bleed air for rain removal in some aircraft. helicopters do have wipers though.

vinay dev: 230 knt = kmph?

BroskyWhoDatedHoski: Pilots must have no fear.flying in lightnig storms and rain. I hate driving in the rain.lol

Mii Rich: Rain x

deborshi kashyap: why do airplanes move slowly during the taxi

Christopher Terry: Do windshield wipers effect air flow ?
