Wind, Visibility and RVR

Wind Data

An immediately visible representation of current wind conditions. Depending on source data:

  • Current wind direction
  • Current wind speed
  • Maximum or gust wind speed
  • Wind direction variation
  • Wind measurement status
  • Sensor identification

May be numerical, graphical or a combination.

Visibility Data

From an approved airport visibility sensor or weather-processing system:

  • Current visibility
  • Visibility units
  • Measurement status
  • Sensor identification
  • Data validity
  • Communication status

Where there are multiple measurement locations, the display can identify the corresponding point.

RVR

An operational display interface for RVR information where the architecture supports it:

  • Runway designation
  • RVR measurement position
  • Current RVR
  • Sensor status
  • Data validity
  • Communication condition

The RVR calculation remains the responsibility of the approved RVR processing architecture; the display is the visual presentation interface. Where an RVR system has more than one measuring position (touchdown zone, mid-point, stop-end), label each position, and show values beyond the reportable range (above the maximum or below the minimum) as the source system and Annex 3 reporting conventions require rather than as a plain number.

Confirm display units and averaging periods with the source system; wind is normally shown in knots or m/s, and RVR and visibility in metres. Displays used by the meteorological office and air traffic services for the same parameter should be fed from the same sensors so that all users see matching values. Wind direction on local and ATS displays is normally referenced to magnetic north, whereas METAR/SPECI reports use true north (ICAO Annex 3), and averaging periods also differ (typically 2 minutes for local reports, 10 minutes for METAR); label the reference and averaging period on the display. A display does not replace the wind direction indicator required at the aerodrome by Annex 14, Volume I (§5.1.1).

Match the Source System

Communication Interfaces

Select according to the communication method used by the source system:

  • Ethernet
  • TCP/IP
  • RS-232
  • RS-422
  • RS-485
  • Other manufacturer-specific digital interfaces

Confirm the exact protocol with the AWOS, RVR processor, weather processor or other source equipment. For retrofits, identify existing protocols before selection.

Network Integration

Networked displays can form part of an airport meteorological information infrastructure. Design considerations:

  • Airport LAN connection
  • Network addressing
  • Data routing
  • Network redundancy
  • Communication monitoring
  • Access control
  • Network segmentation
  • Remote diagnostics
  • System cybersecurity requirements

Coordinate with the airport IT and communications team.

Mounting Arrangements

Wall MountingOperations rooms, meteorological offices and maintenance facilities.
Panel MountingIntegrated control panels and airport equipment consoles.
Rack / Cabinet MountingCentralised airport systems where the display is part of a larger assembly.
Console MountingOperational desks and control-room environments.

The mounting arrangement should provide suitable viewing angle, accessibility, cable routing, ventilation and maintenance clearance.

Suited to the Installation Location

Environmental Exposure

Display equipment in airport environments may be exposed to:

  • Temperature variation
  • Humidity
  • Dust
  • Vibration
  • Electromagnetic interference
  • Continuous operation
  • Power disturbances

Choose an environmental rating appropriate to the location. Indoor control-room installations generally differ from outdoor or semi-exposed airfield installations.

Electrical Requirements

Provide a suitable, protected power supply. Considerations:

  • Input voltage
  • AC/DC supply
  • Power consumption
  • UPS supply where required
  • Overcurrent protection
  • Surge protection
  • Earthing
  • Power redundancy for critical applications

Requirements are model dependent and confirmed during technical selection.

Where Supported by the System Architecture

  • Valid data
  • Invalid data
  • Sensor failure
  • Communication failure
  • Source-system failure
  • RVR unavailable
  • Network failure
  • Display-system fault

Status information should be clearly differentiated from actual meteorological measurements to avoid misinterpretation by operational personnel.

A Typical Procedure

  1. Physical inspection — mounting, equipment condition, cable, power and network connections, identification labels
  2. Power test — correct supply and normal startup
  3. Communication test — display to source system
  4. Data test — wind direction and speed, visibility, RVR where applicable, other parameters
  5. Status test — indication of valid, unavailable or faulty data
  6. End-to-end test — sensor through weather processor and communication system to the display

Wind & Visibility Display — Frequently Asked Questions

What is a Wind & Visibility Display?

It presents continuously updated airport meteorological information to operational, maintenance and airfield personnel. It can receive data from an AWOS, weather processor, visibility sensor, RVR system or other approved source, and can be used as a standalone local display or as part of a wider airport weather network.

What parameters can it show?

Wind direction, speed, gust and variable wind information, visibility values and status, and RVR with runway identifier and measurement position where connected to an RVR system. Depending on the architecture it may also show temperature, dew point, relative humidity, pressure, present weather, cloud information, sensor status and alarms. The exact parameters are determined by the connected meteorological system.

Does the display calculate RVR or visibility?

No. The RVR calculation remains the responsibility of the approved RVR processing architecture, and the display is the visual presentation interface. The accuracy and validity of displayed information depend on the connected sensors, weather processor, RVR system and communication interface.

How is it connected to an AWOS or RVR system?

Typical chains are AWOS sensors, weather processor and display, or RVR transmissometer, RVR processor and display. Interfaces can include Ethernet, TCP/IP, RS-232, RS-422 and RS-485 or other manufacturer-specific digital interfaces. Confirm the exact protocol with the source equipment, and for retrofits identify existing protocols before selection.

Should wind direction on the display be magnetic or true?

Wind direction on local and ATS displays is normally referenced to magnetic north, whereas METAR and SPECI reports use true north (ICAO Annex 3). Averaging periods also differ, typically 2 minutes for local reports and 10 minutes for METAR, so label the reference and averaging period on the display.

Does the display replace the windsock?

No. A display does not replace the wind direction indicator required at the aerodrome by Annex 14, Volume I (paragraph 5.1.1).

What units and RVR conventions should be used?

Wind is normally shown in knots or m/s, and RVR and visibility in metres. Where an RVR system has more than one measuring position (touchdown zone, mid-point, stop-end), label each position, and show values beyond the reportable range as the source system and Annex 3 reporting conventions require. Confirm display units and averaging periods with the source system.

How does the display show faulty or invalid data?

Where the architecture supports it, it can indicate valid or invalid data, sensor failure, communication failure, source-system failure, RVR unavailable, network failure and display-system faults. Status information should be clearly differentiated from actual meteorological measurements to avoid misinterpretation.

How can it be mounted?

Wall, panel, console, and rack or cabinet mounting are available. The arrangement should provide a suitable viewing angle, accessibility, cable routing, ventilation and maintenance clearance, and the environmental rating should suit the installation location.

What are common faults and what should be checked?

A blank display points to power supply failure, so check power input and protection. No meteorological data points to a communication failure, so check the source system and link. Incorrect displayed values suggest a data mapping or configuration issue, so verify the source data and interface configuration. Intermittent data suggests a network or cable problem.

Which standards and references apply?

References include ICAO Annex 3, ICAO Annex 14 Volume I, ICAO Doc 9837 (automatic meteorological observing systems at aerodromes), ICAO Doc 9328 (RVR observing and reporting practices), national civil aviation authority requirements and the AWOS or RVR manufacturer requirements. See also the AWOS sensor page.

What should I specify when requesting a display?

The display location and viewing distance, required size and meteorological parameters, number of runways and measurement locations, AWOS and RVR interfaces, communication protocol, data update rate, brightness, mounting, power supply and UPS requirement, environmental conditions, network and redundancy requirements, alarms and status indications, and required documentation.
