Just In Time For OSH

Sandia Aerospace is debuting its new SAC 7-35 Air Data Computer at AirVenture 2005.

Today's integrated Navigation Systems, such as Garmin's GNS 430 and GNS 530 have built-in capabilities that until now have been inaccessible by the majority of system owners. The SAC 7-35 provides the pilot with information to help plan and execute his flight. Operational to 35,000 feet, the SAC 7-35 is being certified as an Altitude Encoder for use with on board transponders, a Fuel Flow System and an Air Data Computer.

The SAC 7-35 accepts Pitot, Static, Heading, Track, Fuel Flow, Outside Air Temperature and Baro Correction. When interfaced to the GNS 430 or GNS530 it provides real time display of Wind Direction and Velocity, Density Altitude, Baro Corrected Altitude, Fuel Flow and Out Side Air Temperature and True Air Speed. The wind information can help the pilot select the best altitude to ensure the most favorable winds.

Sandia says this translates into better fuel economy which is increasingly important considering today's rising fuel prices. The density altitude information can aid the pilot in determining if takeoff distance. The fuel flow information aids the pilot in fuel management procedures and will alert him should fuel become critical. Keeping an eye on the Outside Air Temperature can alert the pilot to possible icing conditions.

The SAC 7-35 has multiple altitude outputs, including Grey Code for Mode C and Mode S transponders, dual RS232 pressure altitude outputs for modern transponders and legacy GPS systems, dual RS232 Air Data outputs for onboard navigations systems and an ARINC 429 Air Data Output.

The SAC 7-35 also incorporates Sandia Aerospace's Altitude In-flight Monitor (AIM) feature. AIM keeps a constant eye on the pilot's selected cruise altitude and advises him should the aircraft stray off altitude. When the pilot reaches his desired altitude, he simply presses the panel mounted AIM push-button and the annunciator displays the legend 'SET' to let him know that he has set his altitude into the SAC 7-35 's memory. If he deviates more than 100 feet, the AIM annunciator will display the legend 'ALT'. If he strays more than 200 feet, the 'ALT' legend will begin to flash.
