Southern Star on Final for Citation 560/S550 Group RVSM Certification

Southern Star Avionics has completed required flight testing for Cessna Citation 560 and S550 airframes and expects to receive RVSM group certification for the types early next month. The $95,000 installation kits use IS&S digital altimeters with integrated air-data computers and analog interface units. The company said the upgrade is available for both single and dual flight director aircraft equipped with Sperry SPZ-500 autopilots. Standard equipment provided with the kit includes air-data display units, an analog interface unit, a prefabricated wire harness, circuit breaker panel, pitot-static kit and the hardware needed for installation. Mobile, Ala.-based Southern Star recently gained approval for a similar installation in the Cessna Citation 500/550 and SP series.
