The TX56A and TX57A Nav/Com radios are vital aircraft instruments with a superior user interface, this starts with a high resolution display. All vital information on the TX56 is clearly presented – a display ‘sweep’ function uses a single button to shift the display emphasis from Com to Nav status. The Nav will automatically load the identifier for the selected VOR and over 200 frequencies and identifiers can be saved into the Nav database. The TX56 is dependable, with the capability of providing a fix to a second VOR, improving navigational accuracy. Full support for ILS approaches and a back button allows a back course to be selected and flown.
The Nav/Com display is clear and bright, showing both primary and secondary frequencies along with airfield / VOR identifiers. A ‘Push Step’ knob allows the fastest change from 25 kHz to 50 kHz so the Nav/Com can quickly be tuned without compromising look-out. Dual Watch feature allows monitoring of two Com or Nav frequencies at the same time – it’s like having a second radio.
The radio has a ‘Say Again’ feature. A single button press replays the last radio transmission. This feature is ideal for student pilots, but every pilot can get distracted, so it avoids the embarrassment of asking air traffic to repeat a message.
The Nav receiver is optimized to provide stress free operation. Both the TX56A and TX57A will decode Morse, identifying VORs or ILS. The Nav receiver can monitor a second VOR which significantly enhances route navigation. This means that a standby VOR radial can be displayed in addition to the primary VOR – allowing the pilot to quickly calculate an accurate position fix.
The unit display features a graphical CDI (course deviation indicator) This allows the pilot to navigate without an external CDI. The TX56 also provides support for various display options, using a range of external cockpit instruments.
Once tuned the Nav receiver can identify the station by de-coding its Morse identifier, automatically identifying the selected VOR. Automatic centering of the CDI needle displays a direct bearing to a selected VOR for ease of navigation whilst the to/from button allows you to display the inbound or outbound radial.
The Nav/Com’s low profile design requires no external cooling fans. The compact size and features make it a great choice for both forward and retro-fit installations. Each Nav/Com is designed to easily integrate with legacy products, these include the popular SL30 which is the same height as a TX56. Customers replacing legacy KX155 and KX165 models will easily accommodate a TX56 in their stack, in all cases a TX56 tray will need to be fitted.
