DO-267A, Change 1

Lossy Compression
More efficient use of bandwidth
DO-267A requires lossless data compression
Animated/Looping Products
No current standards or guidelines
NASA Langley conducting HF studies
Expanded FIS/AIS Presentation Standards
Area / Volume Products
Winds/Temps, Icing, Turbulence
TFRs
Gridded Database Products
Cockpit creation and display

AIS/FIS Tactical Applications

New RTCA DO-??
Is DO-267A applicable
FIS-B provides information that is advisory in
nature and considered non-binding advice
FIS-B equipment determined to have failure
conditions classified to at least a minor
hazard classification
Need for Operational Services and Environment
Definition (OSED) and other approval documents
Tactical vs Strategic applications
RTCA DO-264 process
Integration of FIS/AIS with Data-Driven Charts

9
DO-252, Change 1

Minimum Interoperability Standards (MIS) for
Automated Meteorological Transmission (AUTOMET)
Add message formats
Turbulence
Wake Vortex Avoidance
Water Vapor and Icing
Review AUTOMET formats for consistency and
interoperability
Consider ICAO AMDAR formats
Review TAMDAR implementation for sensor/data
formats
