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 8.33 kHz to 25 kHz (TX56/TX57) or 25 kHz to 50 kHz (TX56A/TX57A)- so you can tune the Nav/Com quickly without compromising your look-out. Dual Watch feature allows you to monitor 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 optimised to provide stress free operation. Both the TX56 and TX57 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.
BUILT IN CDI
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.
