SUPPLEMENTARY INFORMATION: 

History 

In 1999, the FAA established an 

Aviation Weather Technology Transfer 

(AWTT) Board to manage the orderly 

transfer of weather capabilities and 

products from research and 

development (R&D) into operations. The 

Director of the National Airspace (NAS) 

Weather Office, Operations Planning, 

Air Traffic Organization chairs the 

AWTT Board. The board is composed of 

stakeholders in the Air Traffic and 

Aviation Safety organizations in the 

Federal Aviation Administration and 

the Office of Climate, Water and 

Weather Services, the Office of Science 

and Technology, and the National 

Center for Environmental Predictions 

(NCEP) in the National Weather Service. 

The AWTT Board meets semiannually or as needed to determine the 

readiness of weather R&D products for 

experimental use or full operational use 

for meteorologists or for end users. The 

board makes the determination based on 

technical and operational readiness, 

cost and benefits, user needs and budget 

considerations. 

FAA has the sole responsibility and 

authority to make decisions intended to 

provide a safe, secure, and efficient U.S. 

national airspace system. However, it 

behooves FAA to not make decisions in 

a vacuum. Rather, FAA is seeking 

inputs from the user community before 

decisions are finalized. 

Industry users are invited to 

participate in one-day meetings about 

three times per year to give specific 

feedback to the Government. Meetings 

will be focused on a specific domain 

(e.g. terminal, enroute) or specific 

weather phenomena (e.g. turbulence, 

convection). Meetings will include a 

time for users to provide input on 

specific weather products and aviation 

weather road maps and to surface issues 

or concerns with those products. The 

industry review sessions will be 

announced in the Federal Register and 

open to all interested parties. 

This meeting is the industry session 

focused on convective weather 

products, roadmaps and research 

activities. 

Meeting Procedures 

(a) The meeting will be informal in 

nature and will be conducted by 

representatives of the FAA 

Headquarters. 

(b) The meeting will be open to all 

persons on a space-available basis. 

Every effort was made to provide a 

meeting site with sufficient seating 

capacity for the expected participation. 

There will be neither admission fee nor 

other charge to attend and participate. 

This meeting is being held in 

conjunction with the NBAA Convention 

2005. There is a charge to attend the 

NBAA convention; however, any person 

66306 Federal Register / Vol. 70, No. 211 / Wednesday, November 2, 2005 / Proposed Rules 

desiring to attend this informal meeting 

will be admitted by NBAA convention 

officials to this meeting only, at no 

charge. 

(c) FAA personnel will conduct 

overview briefings on aviation weather 

products, aviation weather roadmaps 

and the status of on-going research. 

Research leads from the convective 

weather product development team will 

conduct an overview briefing on the 

status of research efforts in the 

convective weather domain. Questions 

may be asked during the presentation 

and FAA personnel will clarify any part 

of the process that is not clear. 

(d) FAA personnel will lead a session 

intended to elicit user views on the 

convective weather products and any 

issues surrounding those products. Any 

person present may offer comment or 

feedback in the session. Comments and 

feedback will be captured through 

discussion between FAA personnel and 

those persons attending the meeting. 

(e) FAA will not take any action items 

from this meeting nor make any 

commitments to accept specific user 

suggestions. An official verbatim 

transcript of the meeting will not be 

made. However, a list of the attendees 

and a digest of discussions during the 

meeting will be produced and posted on 

a Web site. Instructions to access the 

Web site will be provided to all persons 

attending the meeting and provided to 

any who desire it. 

(f) Every reasonable effort will be 

made to hear each person’s feedback 

consistent with a reasonable closing 

time for the meeting. Written feedback 

is also solicited and may be submitted 

to FAA personnel for the period 

November 11–December 10, 2005. 

Agenda 

(a) Opening Remarks. 

(b) Review of AWTT weather 

products, roadmaps and research efforts. 

(c) Convective Weather Products and 

Issues Session. 

(d) Closing Comments.
