JouYang Electrical: airspeed indicator manufacturer and airspeed indicators design in China.

Established in 1990, China JouYang Electrical Products Co.,Ltd. is known as a leading airspeed indicator manufacturer and designer of high and low-voltage electric appliance in China. We integrate scientific research, development, production, sale and service in one company. Our custom airspeed indicators products are characterized by their superior dustproof, splash-proof, anticorrosion, fire-resistant, thermo-stability and aging-resistant properties. Having received ISO9001 certification for our manufacturing and sales systems, we have also been issued European 'CE' and Chinese 'CCC' safety authorizations for our products. All of our OEM airspeed indicator products are strictly according to IEC/GS/EMC/LICE/UL/CSA standard and guaranteed by People's insurance Corporation of China (PICC).

The 7000 Series Vertical Speed Indicator is a precision instrument, which provides an accurate and reliable indication of rate of change of altitude. Ascent is indicated by a clockwise rotation of the pointer from zero. Descent is indicated by a counter clockwise rotation. Zero is at the 9 o'clock position. Stops limit pointer movement at the end of the scale. A zero adjustment screw is located on the face of the case at the seven o'clock position.
Certification: FAA TSO C8b
Case Configuration: MS33549, 3 inch
Typical Weight: 1.2 Pounds
Range: 0- 2,000, 3,000, 4,000, or 6,000 fpm
Static Pressure Connection: 1/8-27 ANPT
Installation: Removable spring nuts and #6-32 Screws
Lighting: Available upon request

The MacCready type ring is an indispensable aid in cross-country soaring.The ring is rotatable and is marked with speeds and a white triangle.The chief use of the MacCready ring is to achieve the highest possible cruising speed (average cross-country flying speed) on thermal cross-country flights.This involves setting the white arrow to the anticipated rate of climb for the next thermal.Optimum flight performance is assured when the airspeed indicated by the airspeed indicator corresponds to the preselected flying speed to which the MacCready ring has been set.The MacCready ring allows gliding distance and final approach to be optimized.Please refer to relevant literature for further details.When ordering, please do not forget to state the type of aircraft in which the ring will be used. If the ring is retrofitted to a variometer of older design, the original threaded ring of the instrument must be removed and replaced by a grooved threaded ring onto which the MacCready ring can be fixed with ease.
This model comes with an unmarked ring that you can mark to match the polar of your glider.
