History

The high-wing had two open, one behind the other cockpit. In the proposed variant Fw 47B for the Argus As 10C engine a Roots blower was provided to improve the level of performance. However, the engine did not achieve mass production.

The first production version Fw 47C reached with an Argus AS 10C with 240 hp, a top speed of 190 km / h Besides the new engine, a radio was installed and the rear cabin equipped with a windshield. To increase the rate of descent and to shorten the long Anschwebestrecke this variant also received airbrakes on the outer wings. The meteorologists this aircraft was known as the " height vultures ".

The version Fw 47D received a further stronger Argus engine of type As 10 E with 270 hp. A machine received a runners - chassis for use in snow. This variant also received improved equipment with an autopilot. A total of 35 machines were built of this variant.
