Airport Windsock

Square sock.png

1 Introduction

The Airport Windsock from Shergood Aviation uses animesh to create a unique aviation product for your airport. Features include:

  • Over 20 separate animations for different wind conditions
  • Speed/direction controlled via Shergood or Linden wind
  • Conforms to FAA standards for windspeed vs bend location
  • Medium and large versions include flood lights and beacon
  • Lights controlled via menu or Nexus Lighting System
  • Full materials on sock fabric and support structure
  • Manual control mode
  • Comes in small, medium and large sizes

2 Basic Usage

To use your windsock, simply rez the base of the desired size at the desired location. The base will rez the actual sock which will immediately begin interacting with the current wind. The sock is made with animesh with separate animations for windspeeds between 0 and 20 knots. By default, the windsock will show wind from the Shergood Weather System, but you can also configure it to use Linden wind, commands on a specified chat channel, or to simply cycle through the wind speeds.

While the sock is a separate object form the base, it will automatically track the position of the base as you move it, as long as you remain in the same region, and keep any movements to no more than 200m in one move. If you delete the base, or if the sock looses track of the base, it will self-delete. If the sock is lost for any reason, you can click the base and select RESET from the menu to reset the scripts and cause the sock to be rerezed.

2.1 Lighting Control

The medium and large versions of the windsock come with a flashing beacon and flood lights. The lights can be controlled through a menu by clicking the base. The menu includes buttons for MASTER, beacon, and flood with an indicator to show which switches are on or off. The MASTER switch can be used to turn off the entire system and is normally kept in the ON position. The flood and beacon are then controlled by the other two buttons.

3 Configuration

The windsock contains two configuration notecards *config and _light-cnf. The _light-cnf controls the look and feel of the lighting and normally never needs to be modified. The section will focus mainly on the *config notecard.

Each line of *config consists of a key/value pair separated by a colon (:). Comments are any text from a # to the end of the line. The configuration consists of two sections, a basic configuration section which sets up the functioning of your windsock, and a Nexus section which enables you to connect the lighting on your windsock to the Nexus lighting system.

The default *config notecard (for the medium windsock) contains the following:
#
# Basic windsock configuration
#
TYPE: sa                  # sa, linden, sequence, chat
CHAN: 9                   # channel for manual control (only applies to "chat" type)
PREFIX: wind              # prefix for manual wind commands (only applies to "chat" type)
SCALE: 3.45235            # speed scaling (only applies to "linden" type)
OFFSET: <0,0,1.9592>      # offset for rezing sock
ACCESS: owner             # who can access the switch menus (list including owner, group, or usernames)

#
# Configure for Nexus compatibility.
#
nexus_enable: 0                                 # use 1 to enable, 0 to disable 
nexus_BreakerID: windsock                       # Breaker name (covers all lights on device)
nexus_SwitchID_flood: windsock.flood            # Flood light ID
nexus_SwitchID_beacon: windsock.beacon          # Beacon ID

3.1 Basic Configuration

The basic configuration options are as follows:

Key Description
TYPE This option specifies the type of wind that is shown by the windsock. Possible values are "sa" for Shergood Weather, "linden" for Linden wind, "chat" for chat controlled wind, and "sequence" for sequencing through the wind animations.
CHAN When using chat controlled wind, this specifies the channel to be used.
PREFIX When using chat controlled wind, this specifies a prefix to be used to indicate which lines should be interpreted as a wind control.
SCALE When using Linden wind, this specifies the scale factor between RL knots, and in-world knots. The default of 3.45235 is the scale factor used by Shergood aircraft.
OFFSET This specifies the offset from the base at which the windsock is rezed. Normally, this value should not be changed and is different in each of the three different sizes.
ACCESS Specifies who can use the light control buttons in the menu. By default, only the owner can use the menus. You can additional specify a list including group or any SL usernames to whom you would like to grant access.
