**Initiatives in Aviation Weather Dissemination**

- Version 1.0

## High Priority Initiatives Addressing Dissemination

**Improve ground-ground weather communications  **
***Appears in 6 of 8 service areas***
**Develop a 2-way FIS data link capability  **
***Appears in 7 of 8 service areas***

- Version 1.0

## Topics

**Internet policy**
**Industry data access**
**Flight Information Services (FIS) data link**

- Version 1.0

## Drivers for Use of Internet

**Drivers for Use of Internet**

**Large ground communications infrastructure costs have been a major constraint to both government and industry**
**Internet technology promises a cost-effective solution **** **

- Version 1.0

## Standards for Use of Internet

**The purpose is to establish:**
***Standards for reliability, accessibility, and security  for the weather/NOTAM dissemination via the public Internet***
***Procedures for FAA to determine vendors’ compliance with these standards***
**Vendors who meet standards will be placed on a FAA list of Qualified Internet Providers**

- Version 1.0

## Standards for use of Internet (Continued)

**Vendors can become Qualified Internet Providers by either**:
***Showing a contractual relationship with end users:***
- contract can address data reliability, accessibility, and security
***Demonstrating compliance with the standards***

- Version 1.0

## Standards for Use of Internet (Continued)

**Qualified Internet Providers may be:**
***Approved Sources: ***** Vendors approved by NWS or FAA and listed in a carrier’s Part 121/135 Air Carrier Operations Specification, paragraph A10**
**Vendors serving general aviation, not necessarily “Approved Sources”**
**Vendors who are not Qualified Internet Providers may continue business as in past.**

- Version 1.0

## Three areas of consideration:
Reliability: system availability 24/7 with 99.99?? up time
Accessibility: 100% of users can complete server session within 2 minutes
Security:  
data won’t be intercepted or corrupted
bogus data won’t be allowed
senders can prove what they sent
users can prove what they received

***Reliability: ***_**system**_** availability 24/7 with 99.99?? up time**
***Accessibility: *****100% of users can complete server session within 2 minutes**
***Security:  ***
*data won’t be intercepted or corrupted*
*bogus data won’t be allowed*
*senders can prove what they sent*
*users can prove what they received*

**Standards for Use of Internet (Concluded)**

- Version 1.0

## Process for Qualification and Implementation 

- Note: The process for approving sources is a separate process that will be administered by the FAA and NWS.

- Version 1.0

## Next Steps

**Policy will be published as AC**
**Target publication = September 2000**

- Version 1.0

## External demand for data on the rise for FAA systems developed for internal use
General FAA policy:
FAA provides user access at system ports
Users are responsible for communication costs
ATA held users’ needs meeting in August, 1999
ITWS access was one of airline users’ higher priority   

**General FAA policy:**
***FAA provides user access at system ports***
***Users are responsible for communication costs***
**ATA held users’ needs meeting in August, 1999**
***ITWS access was one of airline users’ higher priority   ***

**Industry Data Access**

- Version 1.0

## Summary Users Needs (ITWS)

**Make available to all users at a single point of connection, all ITWS products for all ITWS locations**
**Utilize existing AOC/FAA telecommunications infrastructure to the fullest possible**
**Provide products and data to users in both data structure and image formats **
**Provide automatic product updates to user selected products   **

- Version 1.0

## Summary Users Needs(Concluded)

**Make ITWS locations & products user-selectable**
**Provide technical and specific meteorological (i.e., how to use products) training **
**Provide appropriate documentation **
**Next Steps:  ATA-hosted workshop planned for August to assess progress and plan for future actions  **

- Version 1.0

##  FIS Policy Overview

**Government**
***Make NAS status and existing Federal Meteorological data equally accessible to all users including service providers***
***Make available VHF radio spectrum to selected vendors on a competitive basis***
***Collaborate with other Government, users, and industry to develop common standards and guidelines for FIS services in the cockpit      ***

- Version 1.0

##  FIS Policy Overview (Concluded)

**Industry**
***Provide needed ground infrastructure and avionics to users***
***Provide ***_***basic FIS products***_*** and services to all properly equipped users at no direct cost to the Government***
***Provide ***_***value-added products***_*** for fee  ***
**Users**
***Acquire avionics at their own cost***
***Receive basic products at no cost***
***Pay for value-added products***

- Version 1.0

## FIS Standards Setting

**FIS Standards Setting**

**Special Committee (SC-195), meeting under the umbrella of RTCA for Flight Information Services Communication (FISC)**
***SC-195 has published RTCA/DO-252 “Minimum Interoperability Standards (MIS) for Automated Meteorological Transmission (AUTOMET)” January 11, 2000***
- AUTOMET defines uplink and downlink message formats and specifies a set of encoding and decoding rules to apply to the message format types

- Version 1.0

## FIS Standards Setting (Continued)

***The committee is currently working on the Minimum Aviation System Performance Standards (MASPS) for Flight Information Services-Broadcast (FIS-B) Data Link***
- The MASPS contains the standards for FIS-B, an automated, digital data link system which will provide non-control, advisory information to pilots to operate more safely and efficiently in the NAS.
- The goal is to publish the MASPS in early 2001

- Version 1.0

## FIS Standards Setting (Concluded)

**SC-195 anticipates a change 1 to the MASPS that will include:**
***Further cockpit display guidelines including use of colors and symbology***
***Development of new broadcast products***
