# 1.0 [SCOPE]{.underline}

## [Identification]{.underline}

This specification sets forth the functional and performance
requirements for Direct User Access Terminal (DUAT) Service. To
facilitate traceability, individual requirements have been assigned
unique identification numbers encased in brackets (e.g., \[000\]).
Appendix E to this specification contains a cross reference between
specification paragraphs and identification numbers. References to
Automated Flight Service Stations (AFSSs) and Flight Service Stations
(FSSs) within the specification apply equally to both types of
activities.

## 1.2 [System Overview]{.underline} 

DUAT Service is an Internet-based weather information and flight plan
processing service provided by the Federal Aviation Administration (FAA)
through designated Service Providers for United States civil aviation
pilots and other authorized users. It allows pilots to use personal
computers or remotely connected computer terminals to access an FAA
database to obtain weather and aeronautical information, to file, amend,
and cancel flight plans, and to close Visual Flight Rules \[VFR\] flight
plans. Pilots can connect to the DUAT Service low-speed (ASCII)
interface via a communications circuit providing toll free telephone
numbers or to the high-speed interface using popular Internet
web-browsers.

Major DUAT Service functions include the capabilities to:

> \(a\) Provide a selection of weather information formats (standard,
> abbreviated or outlook) for routes or defined areas,
>
> \(b\) Process flight plans and associated messages,
>
> \(c\) Encode/decode location names and location identifiers (LOCIDs),
>
> \(d\) Provide select weather graphic products,
>
> \(e\) Provide information services to FAA offices, and
>
> \(f\) Ensure that the security of the NAS is not compromised by the
> delivery of DUAT Service.

## 1.3 [Document Overview]{.underline}

This document is organized as follows:

products that have:

(a) Expired, \[060\]

(b) Exceeded their valid period, \[061\]

```{=html}
<!-- -->
```
(c) Exceeded their retention period, \[062\] or

(d) Been canceled \[063\].

#### [Corrected or Amended Weather Products]{.underline}

When a weather product is received by the DUAT Service indicating that
it is a Correction (COR) or Amendment (AMD) to a previously issued
product, the COR \[064\] or AMD \[065\] product must be considered the
latest version. The retention period for COR or AMD products is based on
the retention time of the original product.

#### 3.2.1.3.3.6 [Reserved]{.underline}

#### 3.2.1.3.3.7 [Routine Delay Weather Products]{.underline}

Weather products that are transmitted after their scheduled time may

\[066\] be retained in the database according to its data type,
location/product identifier (ID), and date/time, just as any other
incoming product.

#### [Processing Requirements]{.underline}

All transactions must \[932\] be completed in a timely manner. A
transaction begins when a user successfully logs onto the DUAT Service
and ends when the connection is terminated in accordance with the
provisions of paragraph 3.2.1.5.1.6. The functions included within one
transaction are defined in paragraph 3.2.1.4.5.1.

#### [Database Maintenance]{.underline}

#### 3.2.1.4.1.1 [Alphanumeric Weather Data]{.underline}

#### [Flight Plan Error Rate]{.underline}

The DUAT Service error rate for flight plan messages filed with the
ARTCC must \[526\] not exceed one (1) percent on a weekly basis.

Flight plan error rate must \[527\] be computed as the number of flight
plan errors (a flight plan error message may identify more than a single
error) divided by the number of flight plan messages filed, expressed as
a percentage.

A flight plan reject message must \[528\] be counted as an error unless
the reason for reject was for the flight plan being a duplicate
transmission.

Other errors, which are determined by the FAA not to be the fault of the
DUAT Service, will be excluded from the error rate computation.

#### 3.2.1.6.4 [Qualified Internet Communications Provider (QICP) Requirement]{.underline} 

The SP must achieve and maintain status as a QICP
[\[1507\]]{.underline}. As such, the SP must install and use Secure
Socket Layer (SSL) encryption for CFR Part 121 and 135 operators to
fully comply with requirements outlined in Advisory Circular AC 00-62,
dated 11/01/02. [\[1508\]]{.underline}

After the SP achieves QICP status, the SP must display a warning label
on its Internet site. [\[1509\]]{.underline} The following language is
recommended for the label: This Qualified Internet Communication
Provider's (QICP) servers and communication interfaces are approved by
the FAA as secure, reliable, and accessible in accordance with AC
00-62. 1) This QICP does not ensure the quality and currency of the
information transmitted to you. 2) You the user, assumes the entire risk
related to the information and its use.

#### 3.2.2 [Reserved]{.underline}

3.2.1.6-1. Events such as natural disasters and Government
communications circuits failures must \[073\] be included in the Ao
calculations but these will not be counted against the SP's service
requirement.

DUAT Service availability must \[536\] be computed as:

> Ao = (total time -- total down time / total time) x 100

\[543\] comply with MIL-STD-1472, paragraph titled Error Management/Data
Protection, except where superseded or extended by a requirement in this
specification.

distinct indication to confirm a requested system action \[546\], or an
indication that the action was not performed \[547\].

#### [Feedback Time]{.underline}

When any user request takes more than 3 seconds to complete, the DUAT
Service must \[548\] provide a message/icon indicating that the system
is working on the user\'s request.

#### [Error Messages]{.underline}

The DUAT Service must generate system error messages \[549\] and user
input error messages \[550\] written in plain language text. The
messages should aid the user as much as possible without reference to a
FAA-approved manual.

#### [Command Response Message]{.underline}

The DUAT Service must \[551\] respond to all fulfilled commands with an
acknowledgment indicating successful completion.

#### [Command Error Message]{.underline}

The DUAT Service must respond to all unfulfilled commands with messages
identifying user input or syntax errors in these commands \[552\], and
system errors detected in the performance of these commands \[553\].

**APPENDIX A**

**[STATIC FLIGHT DATA]{.underline}**

Because the actual amount of storage necessary to store the GFE static
data is dependent on the implementation, the only sizing guidelines that
can be given are for the input size of the weather data and the number
of entries in the static data records. The table below provides sizing
guidelines for the static data. Data size estimates for the weather data
are incorporated in Appendix C.
