Testing revealed vortices from the nose chines interfering with intake air, which led to the development of a computer control system to open the forward bypass doors. A computer system to reduce unstarts was also developed. They also developed a flight engineering computer program called Central Airborne Performance Analyzer (CAPA) that relayed engine data to the pilots and informed them of any faults or issues with performance and indicated the severity of malfunctions.<sup id="cite_ref-nasa.gov_20-0" class="reference"><a href="#cite_note-nasa.gov-20"><span class="cite-bracket">[</span>19<span class="cite-bracket">]</span></a></sup> </p><p>Another system called Cooperative Airframe-Propulsion Control System (CAPCS) greatly improved the control of supersonic aircraft in flight. At such high speeds even minor changes in direction caused the aircraft to change position by thousands of feet, and often had severe temperature and pressure changes. CAPCS reduced these deviations by a factor of 10. The overall improvements increased range of the SR-71 by 7 percent.<sup id="cite_ref-nasa.gov_20-1" class="reference"><a href="#cite_note-nasa.gov-20"><span class="cite-bracket">[</span>19<span class="cite-bracket">]</span></a></sup> </p><p>Of the three YF-12As, AF Ser.
