RVSM Operation Approved for JetStar II
Following approval several months ago of RVSM equipment in the JetStar II, Duncan Aviation reported that it has received group approval for RVSM operations for the four-engine business jet. Last February, the Lincoln, Neb.-based company completed the installation and certification of dual IS&S altimeter/air data units in a JetStar 731, the first step in adding these aircraft to group RVSM approval. The installation includes an analog interface device that will provide digital-to-analog coupling to properly interface with the autopilot and flight director. RVSM certification will be priced at about $175,000 per aircraft. Duncan said the group approval will not include some JetStar 731s because they lack key avionics common to the group.
