Cambridge 302 vario & 303 navigation unit instructions.

The CAI 302 is a very nice modern electronic variometer, flight computer and approved flight recorder. Additionally it has a serial port on the back that can drive a moving map flight computer such as XC Soar or Oudie. (It is also possible to add a bluetooth system such as a K6 BT mux that would allow it to talk to an android phone for use with XC Soar).

As of July 4, 2011, our Cirrus was equipped with a Cambridge 302 Vario/flight recorder, which can be used to log flights for SSA badge submittals.  Below is the downloadable calibration form, which must be attached your SSA badge

C302 Calibration Form, though a newer one will be needed now that it expired.

Comment:
Although the Standard Cirrus was a follow-on to the original Open Class Cirrus design, it is completely different aircraft, with a 15 m. wing with airbrakes on the top surface only, an all- moving T-tail and a steel tube skeleton in the wing-fuselage center section. A Cirrus won the U.S. Standard Class Nationals in 1969. Despite a claimed L/D ratio of 38, measured performance by both Paul Bikle and Ricard H. Johnson demonstrated less than 36. In 1975 an improved version called the Cirrus 75 was introduced with redesigned wing fairings, larger airbrakes and other improvements. 176 were manufactured under license by Burkhart Grob in Mindelheim, Germany. After production in Germany ceased in 1977, the Standard Cirrus was manufactured in Serbia by Vazduhoplovno Tehnicki Centar (later Jastreb Fabrika Aviona Jedrilica), first the Cirrus 75 and 75B version, and subsequently a modified Cirrus 81 with roomier cockpit and variable incidence tailplane. Between 1977 and 1978, the French company Lanaverre Industrie built 35 ships designated CS 11/75 L St. and CS 11/78 L St. These ships overlap the German serial numbers with serial numbers beginning at one.
