The PNG system consists of one base station and one or more handheld rechargeable
radios, chargers for the handhelds, as well as an optional control panel connected to the
base station. The PNG Base Station and Control Panel are installed in the aircraft and
supplied with power from the aircraft system.

The PNG handhelds implement functionality to suppress surrounding noise, and to secure
optimal voice activation performance. They implement functionality to connect to the PNG
Base Station in the helicopter (intercom mode), as well as functionality to communicate
directly with other PNG handhelds, or handheld to other radios (direct mode).

The handheld radios are designed to be mechanically robust and the MP50 handheld radio is
waterproof down to a depth of 3 meters to withstand extreme operating scenarios typically
experienced in a SAR and multirole-configured aircraft.

Through the handheld internal microphone, the system enables communication with the
survivor/ground rescue party without helmet removal.

Depending on the configuration and part number, the handhelds are equipped with a GPS
receiver. The position of the handheld device may be polled by the PNG Base Station, and
presented on the PNG Control Panel in the aircraft.

The PNG Base Station is typically connected to the aircraft ICS, and may support multiple
connection points for audio. It is capable of delivering a PTT signal to other systems, as well
as triggering transmission based on a received PTT signal or VOX activation.




1.3 Radio
The PNG system operates a wireless link between the PNG Base Station and the handheld
radios in the UHF band. Exact frequency configuration is done at production, based on
customer input to available frequencies and bandwidth in the region they are to be operated
in. The PNG system will normally be configured within a 10 MHz band in the frequency range
397 to 470 MHz. The PNG Base Station will support the full 397 to 470 MHz range
(depending on the antenna installation in the aircraft), while the handhelds support 10 MHz
bands through the 397 to 470 MHz band, depending on the installed antenna. Antennas are
available through the band.

The wireless link is a single frequency, duplex, interception free, digital radio link.

The handheld radios will operate at an output power of up to 400mW using a licence specific
frequency allocation.

The PNG system will not set any limit to the number of simultaneous receivers, but the
number of simultaneous transmitters is limited by the available bandwidth and allocated
timeslots. The PNG system allows three simultaneous transmitting handhelds.

The handheld radios support Maritime VHF mode, and channels can be configured in the
156-162MHz band.

Section 2:                 Operation

The PNG system consists of one PNG Base Station and one or more handheld radios. To
make all units in the PNG system interoperable, each unit must be configured with
compatible parameters. Configuration of the PNG system will imply setting of radio
frequencies, defining groups and setting scrambling or encryption parameters.

Multiple configurations may be stored on a device to support different operational modes.

The PNG system can be preconfigured from the vendor, or the configuration may be set by
the operator’s avionics department.

Ahead of flight all units in the PNG system will be set to compatible configuration. Different
types of operation may use different configurations, due to radio frequencies, group
definitions or other parameters. During operation and in flight the configuration on the PNG
Base Station is normally not changed, but may be required in some special conditions. Such
conditions may be caused by radio interference, where alternative frequencies may be
required, and an alternative configuration is selected.

The operational scenario may also require different handheld configurations to be loaded in
different phases of the operation, e.g. to change group subscriptions during the mission.
Switching between the handheld configurations is done by the handheld operator by a simple
button push.

The installation of the PNG system in an aircraft is dependent on the aircraft type and use
scenarios. The PNG Base Station may be installed in a static configuration with circuit
breaker and a switch for power, and optionally switches for mute and broadcast. The system
is in this configuration locked into one configuration for the Base Station.

Alternatively, and recommended, a PNG Control Panel may be installed. The PNG Control
Panel supports rotary buttons and discreet buttons, for controlling active configuration, mute
and broadcast, as well as power on/off. There is also a display that gives status information.

Actual placement and operation of switches or PNG Control Panel is dependent on the
aircraft type and installation.




2.1 Groups
The PNG Base Station supports organising the communication on the wireless link into
groups. Groups are a set of audio channels on the wireless link, and a set of physical audio
interfaces on the base station. The PNG system will support 2 groups depending on the
available radio resources (channel bandwidth).

The PNG Base Station will by default have audio to and from the first group on physical
audio interface 0 and the second group on physical interface 1.

The handhelds are configured to listen (receive) to one or more groups (allowing
simultaneous listening to multiple groups). Transmit is configured to one primary group

through PTT/VOX, but it is possible to configure transmit to a secondary group through
configuration and use of the secondary PTT on the handheld.

When the PNG system is set up, one or more configurations are defined, see section 2.2
Configurations.




2.2 Configurations
Both the handhelds and the PNG Base Station use configurations to control the behaviour of
the devices. They can hold a number of configurations, with different operational parameters.
A configuration contains a minimum of the following parameters:

    •   Logical name of the configuration
    •   Radio parameters (frequency, modulation, and channel bandwidth)
    •   Group subscriptions for receive
    •   Group subscriptions for transmit
    •   Configuration of remote PTT control (handheld activation of PTT from the PNG Base
        Station to the intercom)

The different pre-programmed configurations can be selected at start or during mission from
the PNG Control Panel. Typically, there will be several configurations when different radio
channels shall be made available. There can also be different configurations for different
mission types as e.g. SAR and EMS missions.

The different configurations are selected on the PNG Control Panel with a rotary push button,
and identified by the logical name. When selected, all relevant parameters are loaded.

On the handheld, the configuration is selected with the up/down arrows, and identified with a
short two letter name and a long logical name (scrolling display).

Pre-programmed configurations can either be pre-ordered from the equipment vendor, or
changed by a qualified equipment operator with a PC based programming tool.

2.2.1   Encryption

With the PNG system all user data are encrypted according to the AES-256 encryption
standard before they are transmitted over the air. When delivered from factory, the PNG
Base Station uses a default encryption key called “AXNES DEFAULT”. Changing this
encryption key requires the user to acquire an encryption key programming kit. Note that the
PNG Base Station and all handhelds in a system must use the same encryption key in order
to connect and communicate with each other.

2.10.1 Dimming

If the CP50 is connected to the cockpit or cabin analogue dimming signal, the CP50
illumination will follow the main dimming level in the cockpit or cabin. The illumination of the
PNG Control Panel display and buttons follows the voltage on the dimming pins according to
the dimming curve chosen in the Dimming Curve menu. There are three predefined dimming
curves (Day Mode, Night Mode and NVG Mode), but new ones can be created by the
operator’s avionics department.

Note: With the default dimming curves and no voltage on the dimming pins, the display will
go completely black when the Night Mode or the NVG Mode dimming curves are selected.
The Day Mode has illumination even if the dimming pins have no voltage and is the default
dimming curve chosen after a power off/on, so turning the control panel off and on again can
be used to get illumination back in the display if the display goes black by accidently
choosing a dimming curve with unintended low illumination.

In addition to dimming control on the analogue dimming input according to the chosen
dimming curve, the illumination can be manually adjusted up and down in the Dim Display
menu. The new brightness level is used until the next power off. When turning the PNG
Control Panel off and then on again, the dimming value is reset to a pre-defined value set in
the installation menu.



2.10.2 Poll position

Some of the handhelds provided with the PNG system may incorporate a GPS receiver.
Units with the GPS receiver enabled will register to the PNG Base Station and appear listed
by their configured logical name, under the poll position menu.

The available handhelds can be polled for their position by selecting the handheld name.

The position will appear in the display, initially with dashes, indicating that the position is not
available, while waiting for the GPS lock. As soon as GPS lock is established, the long/lat
position of the handheld will be displayed. The position is updated at a configurable interval,
with a default value of 10 seconds. The position age counter in the top right corner indicates
the age of the shown position. If the handheld loses GPS lock or loses contact with the PNG
Base Station, the last known position will remain in the display while the age counter
continues to count.



2.10.3 Map system

The position of the handhelds can be reported to a map system connected to the PNG Base
Station. The position reporting is turned on and off through the menu on the PNG Control
Panel.

The position is polled at a configurable interval, and reported to the map system at the same
rate. The actual poll rate is dependent on the number of handhelds with active GPS. It is
possible to disable GPS reporting from the individual handhelds by using the menu in the
handheld.



2.10.4 AIS Activation

For handhelds equipped with AIS functionality, the position of the handheld can be sent with
a message format compatible with standard AIS position reports, using the AIS-SART
format. This functionality can be activated either from the handheld with the AIS-button, or it
can be activated remotely from the AIS-menu on the PNG Control Panel.

From the menu on the PNG Control Panel the state of the AIS position reporting for each
handheld can remotely be set to either Off, Test or Active.

    •   The Off-option will deactivate sending of AIS position reports from the chosen
        handheld.
    •   The Test-option will activate sending of one burst of AIS test messages from the
        chosen handheld and then deactivates.
    •   The Activate-option will activate sending of standard AIS-SART position reports from
        the chosen handheld.

Note: Activation of either of these options will override the current state for the chosen
handheld. If the handheld was currently active sending AIS position reports, choosing the
Off-option from the PNG Control Panel menu will deactivate sending of AIS position reports.

When remotely changing the handheld AIS state, this will give an audio feedback to the
handheld user, either via the headset or the internal loudspeaker.

Note: The PNG handhelds are NOT AIS-SART transponder, but implements functionality to
send AIS-SART compatible messages to improve ongoing operations.

2.11 Error conditions
The PNG system status is continuously monitored and indicated in the standby/TX display.
When the system operates with no error detected, the system status is indicated as SYS:
OK. If an abnormal condition is detected, the system status is reported as SYS: ERR, or
SYS: E [error code], where [error code] is a vendor specific number.

If the PNG Base Station is not operating normally, check the PNG Control Panel for error
indications. Check also connectors for proper attachment, and external antenna connection
with cabling.

A malfunction might be corrected by rebooting the system by switching the system off and
then on again.

If the system becomes unresponsive, a hardware reset can be initiated by holding the power
on/off button for 12 sec.

If error condition is persistent, the unit should be sent for service at an Axnes authorised
repair centre.

Authorised repair centres are published at www.axnes.com
