Park Air T6 features and benefits:

Reduced whole life costs. Efficiency is increased and power consumption is decreased, reducing the initial and ongoing costs of power and air conditioning. The combination of up to a ten-year service interval and fifteen-year service lifetime also brings down cost of ownership.

Better environmental performance. The reduced power consumption is a result of our ongoing work to improve environmental standards. No materials specified in the Restriction of Hazardous Substances (RoHS 2) directive are used in the manufacture of the T6 Radio.

Class-leading RF performance. A step-change improvement in the radio RF design has resulted in better interface and co-site performance in the increasingly crowded radio spectrum, reducing the need for external filtering and, in many cases, eliminating it completely.

Flexible main/standby features. These include integral RF/line changeover and software programmable interfaces for controlling external changeover units. Independent AC and DC power options provide additional redundancy.

Advanced temperature control. Digital power management and computer controlled airflow ensure that the radios run cool. This extends component life and reduces the risk of failures.

Intelligent built-in-test. The T6 Radio continually monitors its own environment and performance. If any issues are detected, the radio enters a ‘reduced service’ state, decreasing the power output and alerting the operator with diagnostic information before failure occurs.

Automatic simultaneous call transmission detection. The Park Air SCT technology alerts the operator to the possibility of call blocking and the loss of vital communications between pilot and the ground.

Our most secure radio ever. In addition to front panel screen and interface port locks, there is also support for the latest secure web protocols. These include SNMP v3 with enhanced encryption and authentication, and a secure webserver interface with HTTPS and IPv6/IPv4 compliance.

Designed for future networks and systems.  The crucial parameters of network connectivity, environmental sustainability and long service life have all been central to design and specification decisions.

Three independently addressable IP ports are available: two on the rear for autonomous network connectivity and one on the front for easy browser access to the built-in maintenance web-server.

Software defined waveforms. As well as traditional AM-Voice, a number of data waveform options are also available, anticipating the continued growth in data-link services. These include ACARS, VDL-M2 and Wideband AM Data.

Remote firmware upgrade. The ability to update radio firmware from a remote location reduces the need for radio site visits. Connection to an IP network is all that’s required.

IPv6 core capability. IP connectivity, both for VoIP audio and ‘monitor and control’ data is based on IPv6 (and also works on IPv4), ensuring compatibility with latest-generation networks and systems.

The T6 Radio is half the size and weight of previous models.  You can house more channels in your available cabinet space. A innovative mounting system means that no tools are required for cabinet installation.

Intuitive user interface. A high resolution OLED graphical display is supplemented by a main rotary input control, context-specific soft buttons and indicator icons. There are visual indications of radio activity to accompany the audio.

Loudspeaker to monitor voice transmissions. All T6 Radio models (transmitter, receiver and transceiver) provide a loudspeaker so that voice transmissions can be monitored locally when necessary
