S-TEC Announces WAAS Upgrade For Alliant-Equipped King Airs, Conquests

Also Available For Meggitt Magic-Equipped Cheyennes, Senecas, Twin Commanders

S-TEC Corporation announced Tuesday it has received FAA approval for its Wide Area Augmentation System (WAAS) upgrade for Alliant integrated avionics equipped 90 and 200-series King Airs and Cessna 425 and 441 Conquest IIs. The company also has approvals to upgrade select Meggitt Magic equipped Cessna 425 and 441 Conquest IIs, Twin Commanders and Piper Cheyenne IIs, Seneca Vs, Mirages and Meridians.

"We are extremely excited to be able to offer all the benefits of WAAS to our customers who are flying with the Alliant integrated avionics suite and the Meggitt Magic EFIS system," Greg Plantz, Vice President Sales and Marketing, S-TEC/Chelton Flight Systems said. "I know that pilots flying Alliant and Magic equipped aircraft will be happy to take advantage of all the added safety and operational benefits WAAS has to offer."

Wide Area Augmentation System (WAAS) was developed by the FAA to provide the additional vertical and horizontal accuracy necessary to enable an aircraft’s onboard Global Positioning System (GPS) to be used as its primary means of navigation from take-off through landing including Category 1 precision approaches.

The current WAAS GPS broadcast signals improves GPS signal accuracy from 100 meters (329 feet) down to seven meters (23 feet).

"This added accuracy is extremely beneficial in all phases of flight," Plantz said. "Most notably it will permit the implementation of more precision approach services to airports that currently do not offer them. This will allow pilots to operate into less congested airports that are closer to their destinations. That will save time and fuel."

Plantz said that because of the diversity of installations, some WAAS upgrades would be simple software updates, while others will require changes to some of the hardware on the aircraft. Because the upgrade path is aircraft specific, S-TEC is encouraging each owner to contact their nearest authorized S-TEC facility for details on their WAAS upgrade.
