Just as Dave said. I'd also like to add that there's no such thing as drops on the windscreen in flight -- you're going way to fast for that, even in a slow plane like the 172 or Warrior (even my Warrior cruises over 230 km/h. Extremely heavy rain can sheet over the windscreen, but normally, the drops just follow the boundary layer around the outside of the cabin and appear to fly past horizontally at high speed (snow can be very dramatic that way, with the sun reflecting off each flake as it flies by). On the ground, water drops on the window of a single engine plane often run upwards, from towards the top of the windshield, because of the prop blast.
