Nav/com radios are one of the best investments a pilot can make for their aircraft. Air Plains Services out of Wellington, Kansas can help you with that as they are now offering the new TRIG TX56 and TX57 nav/com units. The TX56 and TX57 are both FAA and EASA certified.

“The availability of the Trig nav/com gives aircraft owners and flight schools a second option in the current market for new units,” said Eric Papon, manager of O&M Services for Air Plains. “It provides a lot of functionality in a small package and integrates smoothly with almost any panel.”

Trig Avionics was founded in 2004 to develop innovative avionics products for general aviation. According to Air Plains, Trig’s TX56 and TX57 nav/com radios are an ideal platform to update legacy avionics and at only 1.3 inches high, provide more panel real estate while offering practical features for any pilot.

Features of the nav/coms include a clear, bright display showing both primary and secondary frequencies along with airfield/VOR identifiers. The ‘Push Step’ knob allows the fastest change from 8.33 kHz to 25 kHz (TX56/TX57) or 25 kHz to 50 kHz (TX56A/TX57A) so the pilot can focus on flying the airplane. The Dual Watch feature allows the pilot to monitor two com or nav frequencies at the same time.

The radio has a ‘Say Again’ feature where a single button press replays the last radio transmission, ideal for student pilots and pilots in heavy workload situations.

Both the TX56 and TX57 will translate Morse code, enabling the pilot to more readily identify VORs or localizer frequencies for ILS approaches. The nav receiver can monitor a second VOR, which significantly enhances route navigation, allowing the pilot to quickly calculate an accurate position fix.

The display features a graphical CDI (course deviation indicator) giving the pilot the ability to navigate without an external CDI. The TX56 also provides support for various display options, using a range of external cockpit instruments.

The TX56 family of products is available with 8.33 kHz channel spacing or conventional 25 kHz spacing and 10-watt (TX56) or 16-watt (TX57) transmit power. The TX56A and TX57A are 760 channel radio versions (non 8.33 kHz for use outside Europe).

Air Plains Services specializes in high performance engine upgrades for most Cessna 172, 180, and 182/182RG piston aircraft, avionics systems and components as well as custom avionics panels, high quality spare parts and enhanced performance systems, and aircraft modification and maintenance.
