SANDIA Aerospace has set yet another standard with the SAC 7-35 Airdata Computer for General Aviation. The SAC 7-35 gives you more bang for for your navigation buck Whether you're upgrading to one of the new generation navigation system or just wanting to get the most out of the system already installed in your aircraft, the SAC 7-35 should be at the top of your system options.

The SAC 7-35 is four systems in one:

• Altitude Encoder. The SAC 7-35 is FAA TSO Approved as an altitude encoder. It provides standard Gillham Grey code for legacy transponders and RS-232 data for the new generations of transponders.
• Altitude Alerting. The SAC 7-35 has SANDIA Aerospace’s exclusive AIM (Altitude Inflight Monitoring) that alerts the pilot anytime he deviates more than 100 feet from his selected altitude.
• Fuel Flow. The addition of a fuel flow transducer (two for a twin) and your SAC 7-35 provides all the fuel flow data your navigation systems needs to monitor your fuel situation.
• Airdata Computer. The SAC 7-35 is a full up TSO'd Airdata Computer offering all of the functions and capabilities of systems costing thousands of dollars more. The SAC 7-35 has multiple interface formats that allow it to provide data to a wide variety of avionics systems.

Designed and manufactured to most exacting standards, you can depend on SANDIA Aerospace products to provide years of reliable service. And every product is backed by a three year warranty and personal service support.

The SAE 5-35 from SANDIA Aerospace has set a new standard in providing accurate altitude data. The SAE 5-35 combines the features of three systems into a single compact and reliable package. ALTITUDE ENCODING …The SAE5-35 performs the functions of an Altitude Encoder by providing Gillham Grey code to the aircraft’s mode C transponder. Innovative pressure circuitry virtually eliminates the warm up time. DIGITAL ALITUDE …The SAE 5-35 provides two RS232 altitude data outputs in 10 foot increments for use by GPS and Terrain Awareness Systems (TAWS). Each RS232 output is totally independent so that a load on one output will not affect the other. And because it provides altitude data from –1000 to 35,000 feet, it can be installed on piston, turbine or jet aircraft. ALTITUDE INFLIGHT MONITORING…(AIM) keeps a constant eye on your chosen altitude and lets you know whenever you deviate more than 100 feet. SANDIA Aerospace has given sight to the "blind" encoder.

What is ADS-B

Automatic Dependent Surveillance-Broadcast (ADS-B) is the cornerstone of the FAA’s NextGen air transportation system. Basically it provides controllers and pilots with an aircraft's position, using GPS position information that is broadcast on either Mode S transponders or UAT’s (Universal Access Transceiver). Pilots will now be able to see real time position of other aircraft in their vicinity, the same information that controllers are seeing.

ADS-B stands for:

A utomatic No pilot or controller action required
D ependent It depends Global Navigation Satellite position input
S urveillance It provides "radar-like" surveillance to equipped aircraft and ATC
B roadcast It continuously broadcasts aircraft position and other data to any properly equipped aircraft and ground station.

Why ADS-B

Full Airspace Coverage ADS-B equipment can be installed in areas where it is not feasible to establish radar-based surveillance equipment. For instance, ADS-B equipment will be installed on oil platforms in the Gulf of Mexico, delivering substantial safety and efficiency benefits to air traffic flying over the area.

TIS-B Traffic Information Service-Broadcast. When fully implemented ADS-B equipped aircraft will be able to receive and display the position of all other ADS-B equipped aircraft in their vicinity, either through aircraft-to-aircraft transmission of position or through the rebroadcast of aircraft position from a network of 794 strategically located ground stations. ITT is currently on track to have the full US network of ground stations in place by the end 2013.

FIS-B Flight Information Service-Broadcast. UAT equipped aircraft with be able to receive transmitted flight information from 794 strategically located ground stations. Initial FIS-B data will include cockpit weather.

ADS-B Formats There are two current systems that will fulfill ADS-B requirements.

1090ES is a based on Mode S transponders. 1090ES (Extended Squitter) systems will ‘squitter’ TIS-B information which can be displayed by other ADS-B equipped aircraft. There is currently no provision for 1090ES to receive FIS-B information.

UAT (Universal Access Tranceiver) is a new and attractive alternative to 1090ES and provides the user with both TIS-B and FIS-B. Initial FIS-B information includes weather in the cockpit. This weather information is free to the user and will carry no subscription fees.

Sandia ADS-B solutions

1090ES for aircraft with Collins TDR94D transponders and Garmin 400W/500W navigators Sandia has the ADC 7-35-01 which allows the Garmin GPS to talk to the Collins transponder. This unit was developed in conjunction with a major helicopter operator. In addition to providing the interface from onboard GPS receivers to Mode S transponders, the SAC 7-35-01 is also a full function airdata computer.

The ACF 314 and ACF 328 simultaneously cool up to three avionics units. Operating on 14Vdc and 28 Vdc respectively the ACF 314 and ACF 328 supply up to 20 cubic feet of cooling air per minute, helping maintain your avionics at a proper operating temperature. SANDIA Aerospace cooling fans use high quality, brushless blower motors and or RunQuiettm technology. These units are FAA PMA's and have passed stringent environmental testing to ensure years of reliable service.
