An article from yesterday includes the following:
...“WAAS-equipped commercial operators will gain access to Category 1 equivalent approach services at qualifying airports where there are no instrument landing systems. This will result in improved safety, including enhanced approach and landing operations in marginal weather.”
WAAS was originally intended to provide Cat 1 precision approach capability and a 200ft decision height. Current WAAS procedures support approaches down to 250ft
As noted in an earlier post, the Next Generation Air Transportation System (NGATS) and Small Aircraft Transportation System (SATS) initiatives are part of a broad effort to expand the utility of underutilized airports. This latest WAAS development is one more step to opening up those airports for future Air Taxi (and other) purposes.
