SUBJECT:   Soliciting Comments by March 20, 2015, on the
           experimental Helicopter Emergency Medical Services
           (HEMS) Tool

NWS is seeking comments on its experimental Helicopter Emergency
Medical Services (HEMS) Tool. HEMS can overlay multiple fields
of interest: ceiling, visibility, flight category, winds,
relative humidity, temperature, icing, satellite, radar (base
and composite reflectivity), G-AIRMETs, SIGMETs, METARs, TAFs
and PIREPs. Overlays include navigational aids, airports and
heliports for the entire United States. More detail is revealed
as you zoom in and individual layers can be turned on or off
independently.  The tool is not a weather product; it is a display
that aggregates a number of existing weather products into a
single, quick-glance, automated graphic. All underlying products
have already gone through a safety risk management process.

HEMS flights represent commercial aviation activity performed by
FAA certificated air carrier operators; therefore, operations
must have the highest level of safety. Per requirement of the
Federal Aviation Administration, the Aviation Digital Display
Site (ADDS) development team created a tool specifically
designed to show weather conditions for short-distance and low-
altitude flights that are common for the HEMS community. By
using a highly interactive and intuitive tool that focuses on
small, localized regions, HEMS operators gain critical weather
awareness to make their flights safer for crews and patients.
