Winter Instruments Grosskinsky Variable Camberflap Ring

General Description

Winter Instruments Grosskinsky Variable Camberflap Ring - As is generally known, wing load, and in turn, the optimum flap positions for the various speed ranges of a variable–flap glider changes with take–off weight. Until now, selecting the right flap position has involved using special tables carried on board or observing a confusingly large number of marks on the airspeed indicator. The new adjustable ring for airspeed indicators makes these complicated methods things of the past.

Grosskinsky Variable Camberflap Ring is a special order item. Please allow approximately 4 weeks Winter Instruments production time. If the Grosskinsky ring is not ordered along with a new airspeed indicator (ASI), please email a photo of your ASI to sales@wingsandwheels.com. This is a requirement by Winter Instruments. Not available for all ASI's. Only the 6 FMS 4 or 7 FMS 4 series airspeed indicators with 510° scales are suitable.

Use above selections for Winter Instruments Grosskinsky Variable Camberflap Ring.

Features

As the photos show, the ring has a double scale for aircraft weight “G” and wing load “G/F”. Four arrows can also be seen, showing the corresponding angles for the flap positions. The number of arrows depends on the number of flap positions for the type of glider in question – are shown here. Like the MacCready ring of the variometer, the rotable ring is simply push–fitted over the airspeed indicator.

Use

Once the take–off weight has been calculated by adding the dead weight of the aircraft, the weight of the pilot and the weight of any water ballast on board, the “G” scale is simply turned until this figure is aligned with the 0 mark of the airspeed indicator. The arrows on the ring now automatically show the correct flap positions on the airspeed–indicator scale. Furthermore, the correct wing load for the take–off weight can be read from the “G/F” scale and entered in the electric variometer, it fitted. If wing load changes in the course of the flight, due to a reduction in ballast, for example, the ring need only be turned back to the new flying weight, and immediately, the arrows show the new, flight–dependend flap positions. The ring is calibrated for a standard preset acceleration of 1 g. If values as high as 1,3 g should occur, as they do in high–performance competition gliding, a second ring with the appropriate values can be fitted during the flight, or changed as required.
