Waas/LPV Upgrade for King Airs with Pro Line 21
Hawker Beechcraft Services (HBS) has begun scheduling wide area augmentation system (Waas) upgrades on Rockwell Collins Pro Line 21-equipped King Air 200/300s. This installation follows the introduction of the King Air C90GTi upgrade announced last March. According to an HBS spokesman, the King Air 200/300 Waas upgrade offers operational flexibility and cost savings associated with direct and curved area navigation (Rnav) routes. Waas Rnav offers improved access to special-use airspace and high-traffic and/or terrain-challenged airports. Additionally, the HBS Waas installation offers greater mission success through the use of Waas-enabled localizer performance with vertical guidance (LPV) approaches. There are currently more than 1,900 LPV approaches certified and in use today. Waas LPV approaches provide decision heights as low as 200 feet with half-mile visibility. The result is improved safety and cost savings associated with the reduction of missed approaches and flights to alternate airports. The price for this upgrade can range from $51,000 to $85,000, depending on the aircraft type and whether it has a single or dual FMS currently installed. Waas upgrades for the Premier IA and Hawker 400XP/Beechjet 400A are nearing completion and expected by the third quarter.
