Used at the following Wetterflugstelle : Hamburg, Berlin, Köln, Essen, Königsberg, München, Gablingen, Norderney, Kiel, Rotenburg
Used up to WW II , but demand for a bigger plan with a crew of 3 forced these planes out of service. Some were used in some Segelfluggruppen , others  were  kept as back ups at the Wetterflugstellen. According to Nowarra 2 planes survived WW II

The Focke-Wulf A.47 FOR METEOROLOGICAL OBSERVATIONS (Flight)

Specifically for meteorological observations, the Focke-Wulf monoplane shown here is  not a high-performance machine, but an endeavour has been made to make it very stable, so that when much cloud-flying has to be done, as must often be the case, the machine is easy to fly " blind." Good climb and a high ceiling were considered more important than speed, and in fact a high speed was regarded as a definite disadvantage, since it might, on occasion, lead to the machine getting too far away from its starting point during an altitude flight in the clouds.
The construction of the A.47 is the usual Focke-Wulf, with a one-piece wing of all-wood construction, and a welded steel tube fuselage. The wing tips show the Zanonia form associated with all Focke-Wulf machines, and which has been found by this firm to give added lateral stability. The wing is carried on steel tube pyramids well above the fuselage.
The engine fitted in the A.47 is the new Argus As. 10, an eight-cylinder Vee inverted air cooled, with direct airscrew drive. Later it is proposed to fit a supercharged engine of the same make.
An unusually extensive equipment of instruments is carried, partly for making meteorological observations, and partly to enable the crew to fly " blind " for considerable periods.
The main dimensions of the Focke- Wulf A.47 are as follows:
Length o.a., 10.5 m. (34 ft. 6 in.) ; wing span, 17.76 m. (58 ft. 3 in.) ; wing area, 35 m.2 (377 sq. ft.). The tare weight is 950 kg. (2,090 lb.), and the disposable load 525 kg. (1,155 lb.), giving a gross weight of 1,476 kg. (3,245 lb.), a wing loading of 42,2 kg. /m.2 (8,62 lb./sq. ft.) and a power loading of 6.7 kg./h.p. (14.75 l b . / h . p . ).
The maximum speed at ground level is 172 km./h. (107 m.p.h.), and the landing speed 77 km./h. (48 m.p.h.). The climb to 4,000 m. (13,100 ft.) takes 34 minutes. The best gliding angle is given as 1 in 10.8.

Focke-Wulf weather aircraft A 47.For
the daily high-altitude flights for weather observation in the upper layers of the atmosphere, the weather flight service requires aircraft that not only have a good
climb speed and maximum altitude, but are also economical in operation, i.e. manage with a moderate propulsion power. A high
horizontal speed is less necessary for a weather aircraft, even undesirable, because very often it is necessary to fly above the clouds without seeing the ground;
in such conditions, too high a speed can easily lead to an excessive departure from the home airport.
- These requirements, which were only partially fulfilled by the weather planes used so far, were decisive for the fact that the Focke-Wulf-Flugzeugbau-A.-G. started the
development of a special aircraft for weather flight, type A 47. In the design, emphasis was placed on good gradients at low horizontal
and landing speeds using an engine of around 200 hp. High stability with good manoeuvrability was also aimed at in order to
facilitate blind flight; thanks to the well-known properties of the Focke-Wulf wing, this task could be solved to such an extent that it is even possible
to pierce clouds from bottom to top with the rudder released. Of course, all experiences regarding the accommodation of meteorological
instruments, etc. are also taken into account.
The Focke-Wulf A 47 aircraft type is designed as a two-seater umbrella high-wing aircraft (for a guide and a weather observer including meteorological instruments).
Particularly characteristic of the aircraft is the large aspect ratio of the wing, chosen with regard to good climbs, and its rather high
position above the fuselage.
Wings cantilevered and continuous; it rests on a wide canopy made of profiled steel tubes. Its profile, which is thick in the middle, tapers outwards
in such a way that the upper side runs straight over the greater part of the wingspan, while the underside has a very weak V-shape. Wing tips Zanonia shape.
The wing structure is a four-belt, torsion-resistant box spar with pine straps and plywood walls, ribbed parts attached to the front and rear and complete
plywood planking.
Fuselage rectangular cross-section, receives the necessary space for the instruments behind the engine stem, accessible from the outside through doors, behind it under a
cut-out in the wing driver's cab, then observer space.
fuselage framework as a truss made of welded steel tubes; un-braced, stiffened by diagonal rods, all important welds are provided with bars and overlaps.
The ailerons in wooden construction with fabric covering are aerodynamic and balanced by weights. The fin braced against the lower edges of the fuselage by means of
steel cables, planked with plywood, has a large adjustment area. The split elevator, which is equipped with flap compensation, consists of steel tubes with
fabric covering, as well as the horizontal stabilizer and rudder.
Rudder actuation by means of handwheel and sides, control lever via ropes and wires.
Chassis on the fuselage lower edges hinged semi-axles, supported by a tension strut to the fuselage and a spring strut to the wing. struts and axles
made of steel tubes and streamlined cladding; Spring strut with air suspension, type Faudi. 810X125 electron wheels with mechanically operated brakes. Tail spur
with grinding plate, rotatable, cushioned by endless elastic rings.
Model aircraft 195/220 hp Argus As 10 (eight-cylinder, V-hanging, air-cooled). Later installation of the same engine type, but with pre-compressor.
Two fuels are already older for 75 kg each in the wing nose, fuel flows to the engine through a natural gradient. Oil tank behind the fire bulkhead in the hull.
Flying equipment is quite extensive considering its intended use (high-altitude and blind flights). In addition to the usual flight and
engine monitoring equipment, it includes a back parachute for guides and observers, Audos or Draeger stevedoring device, Askania self-control device, Ludolph
double gyroscope, FT long-wave Kl and a device with telephony addition.
Scientific equipment two Bosch meteorographs, which can be accommodated in the wing to the left and right of the fuselage. There is also
enough space in the observer room for a camera and other scientific equipment, such as an aspiration psychrometer.
