Wipers!!!
Is it me being a grumpy old rotor head !! Why cannot engineers or designers actually make windscreen wipers for a Heli that work!!! Mind you having done some time (penance) on fixed wing they were not much better. So far I have seen the ones which clear about two inches in front of your face ( if your at cruise speed) and the ones which do a spastic dance all over the place ? anyone got a Helicopter with a good set of wipers that work ? when you need them in the hover!!

The ones on the Chinook worked OK at slower airspeeds, but also did double duty as the standby airspeed indicator - they would slowly inch outboard at airspeeds above 140 knots.

135 are as helicopter wipers go very good. They did need to beef them up though they kept slipping on the spindle due to the way they were bolted on.......that bit must have been the french input....

The wipers on the EC135 are made by Bosch. And the pantograph style wipers are mainly used on buses and boats/ships, a Lorry has "normal" wipers like a Car.
And in addition the windscreen of the EC135 has to be coated with Rain-X or similar product, acc to the Maintenance Manual.

Because bridge windows are flat and don't travel at 120kts+ through the air. Also it doesn't really matter to a ship if a wiper system weighs 500g or 15kg, whereas obviously weight, low drag and space are more of an issue to helicopter designers.
