⚠️Changing the settings within this webpage will not affect a PilotAware.⚠️


All aircraft registered anywhere in the world will have a unique ICAO number. If you don’t know the ICAO (Hex-ID) of your UK registered aircraft, it can be found by searching your aircraft registration in the G-INFO  database on the CAA website. Please check with your local aviation authority. FlightRadar24 is a good resource for Hex-ID identification.

Insert your unique ICAO code in the Hex-ID field. This will make Rosetta ignore any EC messages from your aircraft. Rosetta will also transmit your aircraft ICAO code to receiving PilotAware units and ATOM GRID ground stations. This allows for better identification and situational awareness.

Hex-ID (Manual)

The HEX-ID must be correct.

An example of a Hex-ID is; 405B19


Add your Flight ID (8 characters maximum). Usually your registration I.e. G-ABCD but it can also be anything else such as VINTAGE1, FALCON9 or even UNDEF (undefined). This is received by PilotAware's and ATOM stations.



The Group-ID allows for the easy identification of aircraft within a group fitted with PilotAware. This can be left as PAWGRP which is the default setting. The Group-ID is limited to 12 characters.

For example;

The Eurostar group chooses a Group-ID of 'EV97', which is entered into the Group-ID of each PilotAware unit. Now the Flight-ID of each Eurostar member will have the registration of the aircraft prefixed and suffixed with a hash. #G-EURO#:


Aircraft Type;

The Aircraft Type is transmitted by PilotAware. This is then received by PilotAware and ATOM stations to aid situational awareness.

The Aircraft Types can be found below and in the dropdown.

  • Powered
  • Microlight
  • Glider
  • Motor Glider
  • Paraglider
  • Balloon
  • Jet Aircraft
  • Drone
  • Base Station (RX)
  • Base Station (TX/RX)
  • Base Station (RX) is used when a Rosetta unit is used as a base station. This does not transmit any information. Base Station (RX) will not trigger responses from ATOM ground stations.

Display Traffic Info;

The Display Traffic Info feature allows the operator to choose which This gives you the option of how traffic is identified on your navigational software. Either showing the REG-ID or the Flight-ID or alternating the two.
It is down to the navigation application or glass cockpit to honour this request.

Display Traffic Info

Display Ground Stations;

ATOM stations transmit a location every 15 seconds. For the location of ATOM stations to appear on navigation application, select Enabled. To prevent the locations of ground stations appearing on a display, set disabled.

License Key;

The 16 digit licence key is entered here. Please consult the licensing section of the knowledge base for help on licensing.

Mode-C/S Select;

This enables the Mode C/S functionality. For more information please visit the Mode-C/S Bearingless Detection section of this knowledge-base to ensure that you fully understand its operation and capabilities before enabling.

The options available for selection are;

Disabled: Used to turn the Mode C/S facility off. (default)
Mode-S. Used to detect Mode–S traffic
Mode-CS. Used for Mode C and Mode S detection if you have NO transponder fitted
Mode-CS+Filter . Used as above if you have a transponder fitted. (This facility should be used with consideration of its development status.)

⚠️ Unfortunately, not all navigation applications or glass cockpits support Mode-C/S data. Please consult the manual or support team of your navigation application for more information. This is out of PilotAware's control.⚠️

Mode-C/S Select

Mode-C/S Horizontal Sensitivity;

PilotAware allows you to set your preferred Mode-S Detection Range which varies the sensitivity of the Mode S Alerts to match the environment in which you will be flying.

Ultra-Short Range: This will give you the lowest sensitivity and is intended to minimize alerts when operating in high Mode C/S traffic environments such as transiting through the overhead of major airports.

Short Range: This is a low alert setting for GA use in busier environments.

Medium Range: This is useful for medium to low levels of Mode-C/S traffic.

Long Range: This setting will bring in alerts from a greater range, e.g when operating in low occupancy areas with low traffic volumes. This is not recommended for high traffic areas.

Mode-C/S Horizontal Sensitivity

Mode-C/S Vertical Display Range;

PilotAware allows you to set the vertical separation for the Mode-C/S alerts relative to your aircraft.

This will give you the following options

  • +/- 500 ft (Default)
  • +/- 1000ft
  • +/- 2000ft
  • +/- 4000ft
  • +/- 50000ft.

As an example, +/-500ft will only warn you of Mode C/S transmitting aircraft within +/-500ft of your current altitude. This filter affects navigation application, glass cockpits and voice alerts.

+/-50,000-ft should only be used for testing purposes.  

Mode-C/S Vertical Display Range


This enables the use of MLAT data received from ATOM ground stations to provide the latitude and longitude of Mode S aircraft. Before enabling Mode-S/3D it is a mandatory requirement that you have read, understand and agree with the limitations outlined in Mode-S/3D.

Mode-S/3D Select (Operational Understanding of Mode-S/3D required before use)

Positional Contacts Settings;

This setting defines filters, through audio and visual.

Select Audio Warning Zones is by default set to 3km, 5km, 10km. This means that if a positional aircraft (3D) flies within the preselected range, voice alerts will be triggered. To reduce the number of traffic alerts, reduce the warning zones.

Select Audio Warning Zones

Horizontal Display Range is a filter that can reduce the traffic forwarded to navigation applications and glass cockpit. By default, this is set to 'Display All' meaning, all received traffic is passed onto displays. For displays and apps that do not have built-in traffic filters, a horizontal filter can be set here.

⚠️ This filter can actively ignore traffic data. Please bear this in mind when flying with visual traffic displays and navigation apps.⚠️

Horizontal Display Range

Vertical Display Range is a filter that can stop the processing of traffic at a height relative to your altitude.

⚠️ This filter can actively ignore traffic data. Also, navigation applications like SkyDemon have a secondary height filter that ignores traffic sent by the PilotAware. Please customise this in the SkyDemon app.⚠️

Vertical Display Range

Device Connect Setting;

This changes the connection method that PilotAware communicates with through Wi-Fi. The options allow for FLARM through (TCP), PilotAware protocol through (UDP) and GDL90 protocol through (UDP).

For PilotAware devices running 20200906, select 'All'.

WiFi Protocol(UDP/TCP)

Bluetooth Audio (Rosetta only);

This setting allows PilotAware to communicate with Bluetooth headsets and speakers. This allows for wireless audio alerts.


USB Settings;

This feature lifts PilotAware above other devices in terms of functionality. The Spare USB's can be used to send and receive data from external devices.
A couple of examples are;

GPS out to a Mode-S ES transponder to enable ADS-B out.
Traffic data out to a glass cockpit display.
Connection to a FLARM device to receive direct FLARM messages.

The port numbers are fixed.

USB Settings
Port 1
Port 2
Port 3
Port 4


Profiles allow multiple profiles (Hex-ID and Flight-ID) to be automatically saved as they are entered. This is useful when PilotAware is used in several different aircraft such as club and hire aircraft. The options are
Restore and Delete.


Restore a stored Profile for use in the next flight.

Delete a previously stored profile no longer needed.
