NTSB: ASOS, AWOS Maintenance Needs Attention

摘要

The National Transportation Safety Board (NTSB) is formally asking the FAA and the National Weather Service (NWS) to take steps designed to improve the accuracy of automated weather observations by addressing equipment malfunctions in a more proactive manner. The requests come as the NTSB completes its investigations into the February 15, 2019, fatal crash of a Cirrus SR22 near Ely, Nevada, and the sinking of an amphibious passenger vessel on July 19, 2018, near Branson, Missouri. Seventeen of the 31 occupants aboard the WWⅡ-era "Duck" being used as a tour platform died when it began taking on water in a storm.
