ATIS Policy

VATNZ ATIS Policy

The VATSIM EC policy mandates that ATIS shall have not more than 4-lines.

Note: A "line" is technically a standard 64-character data packet for transmission purposes.

All ATIS used within the VATNZ Division:

  • MUST comply with the VATSIM 4-line rule.
  • MUST conform to the VATNZ ATIS Policy below.

General

The purpose of ATIS is to:

  • Provide proper voice channel switching (1st line in ASRC)
  • Provide operational information, similar to real world ATIS (remaining lines), based on the on-line weather from the network.

Content

Operational information follows immediately after the voice channel switching line and MUST begin with the Aerodrome name and the ATIS Identifier.

Operational information should be presented in the sequence shown, and use standard abbreviations where possible, eg; APCH, ARR, DEP, EXP, PARL, RWY, WND, XW, DW, KTS, VIS, CLD, SKC, FEW, SCT, BKN, OVC, CAVOK, TMP, QNH, WX, Z.

The following items should NOT be included in an ATIS:

  • Controller name and/or rating.
  • The controller’s frequency.
  • Raw METAR data that has not been decoded by the controller.
  • Unnecessary or insignificant optional information.
  • Information that should realistically be provided by voice interaction with ATC.

If space permits, at the end of the ATIS a controller may optionally include important online information explicitly necessary for a pilot whilst conducting their on-line flight. This additional information may include, but it not limited to:

  • The location of necessary maps/charts/routes/procedures

    Note: Additional information should not be included at the expense of required operational information since that would defeat the basic purpose of ATIS.

Blank lines at the end should be eliminated.

The ATIS Identifier should be incremented for each ATIS change.

Note 1: ATIS Identifier codes should be allocated according to the relevant TMA document, otherwise starting from ALPHA. (See special arrangements within a TMA that ensure nearby adjacent ATIS are never the same as each other)

Note 2: ATIS Identifier ZULU is reserved and should not be used.

ATIS Format

New Zealand ATIS do not conform to the ICAO standard, instead having their own codes and unique sequence of information.

The following line should be added to the ATIS Maker URL in Euroscpe:

http://vatatis.nz/gen?apptype=ILS&arr=$arrrwy($atisairport)&dep=$deprwy($atisairport)&info=$atiscode&metar=$metar($atisairport)&newfiles=true&user=$myrealname

This will produce an ATIS in the NZ format.

The following variables are available

The apptype can be user modified depending on what the controller wants and what the airport supports.
Valid values are: ILS, RNAV, GPS, VORDME, NDB, and VISUAL.

The ATC parameter can be user modified depending on the controllers online at the time.
Valid values are: GND, TWR, TMA (for approach and departure) and CTR
Up to 2 values can be entered, separated by a ,
If the second value entered is a lower position (I.E TMA,GND) it will be ignored
If both TMA and CTR are used at NZCH and NZHN, only one controller entry will be present in the ATIS due to both TMA and CTR positions at said airports being called Christchurch Control.

Sequence

The following sequence of information should be used for all VATNZ ATIS:

ATIS ID:Identifier
APCH:approach information where an APP service is in operation
RWY:states arrival runways, then departure runways
OPR INFO:states runway operations such as PARL RWY OPS
WND:direction and strength shown as ddd/ss
XW MAX:shown as nn KTS on RWY nn
DW MAX:shown as nn KTS RWY nn
VIS:shown as nnnn or GT 10KM
CLD:shown as coverage amount then altitude
TT:Temperature in degrees C
DP:Dew Point in degrees C
QNH:shown as nnnn HPa
2000FT:direction and strength shown as ddd/ss

AUCKLAND INFORMATION HOTEL. EXP ILS OR VIS APCH RWY: 23L

QNH: 1018; 2000FT: 250/28

Note 1: The Identifier HOTEL must appear on the first line of the operational information, and it then becomes unnecessary to use it again at the end.

Note 2: Aliases and placeholders etc may be used to generate parts of the above ATIS.

Aliases

VRC

In VRC the voice switching line is automatically inserted and only the operational information is required to be entered by the controller.

For complete documentation refer to the VRC manual.

Position Specific Guidelines

Different ATC positions have different ATIS requirements. This section provides guidelines for each position. The description column provides examples that may be used to provide the minimum compliance. It should be read in conjunction with the Content section above.

Ground ATIS should refer pilots to the associated local Tower ATIS

ATIS AVBL FROM TWR

Note: If Tower is not online, Ground should provide a FULL ATIS if there is a controller providing local control (tower) services at the field for which the ATIS is being created. This can be an overlying center or approach controller. Reference VATSIM Code of Conduct under section C11.1 - C11.7 

TWRFull ATIS

Tower must at all times provide a FULL ATIS that complies with the content guidelines.

ATIS Changes - should be broadcast on the ATC channel to inform adjacent controllers of the new ATIS Identifier and also new RWYs where these have changed.
