NAV/COMM Test Set

Using NAV/COMM for Navigation and Communication

NAV/COMM equipment is so named because it combines a navigation receiver and communication transceiver in one unit. This dual-function unit provides several advantages over a separate NAV receiver and COMM transceiver: they are less expensive, easier to install, require less panel space, and offer additional operating convenience. In short, aircraft personnel can rest assured that NAV/COMM flight line test sets will help them fly safely until they reach their final destination.

Laversab Aviation offers a variety of innovative testing solutions that ensure safe flying conditions, including a multifunctional all-in-one product known as the Laversab Avionics Radio Test System (ARTS) 7000. One of the key attributes of the ARTS-7000 is that it is designed to meet all aircraft radio test requirements in a single unit. Standard tests include radio communication, navigation, distance measuring equipment (DME), Mode S, automatic dependent surveillance – broadcast (ADS-B), and emergency location transmitters (ELTs). Optional tests include user acceptance testing (UAT) and traffic collision avoidance system (TCAS).

Whether from inside the cockpit or around the aircraft, the ARTS-7000 can be controlled wirelessly via a simple yet intuitive touch-screen interface. In addition, the unit is built to reduce upfront costs, simplify aircraft testing, and cover current and future avionics radio test requirements.

NAV/COMM Test Sets

The capabilities of the ARTS-7000 unit are defined by the modules that are fitted to the test set. There are three standard NAV/COMM test set configurations: NAV/COMM only, pulse only, or NAV/COMM and pulse together. For the purposes of this post, the focus will be on the capabilities of the ARTS-700 when configured with only NAV/COMM capabilities. These capabilities include the following:

  1. Communications – VHF band
  2. Communications – UHF band
  3. Communications – HF band
  4. Communication – SelCal
  5. Navigation – Instrument Landing System (ILS)
  6. Navigation – Marker Beacon (Mkr)
  7. Navigation – VHF Omnidirectional Ranging (VOR)
  8. Emergency Location Transmitter (ELT)

In scenarios where testing over the air is performed (i.e., the ARTS-7000 pulse antenna to the aircraft under test antenna), connect the telescopic antenna for all NAV/COMM functions directly to the antenna port on the top NAV/COMM module. Extend this antenna to its fullest length. If a remote antenna is required. select a suitable coaxial cable. Connect one end of the cable to the antenna port on the top of the NAV/COMM module and connect the other end to the antenna tripod adapter. Connect the adapter to the tripod, attach the NAV/COMM telescoping antenna to the adapter, and position the tripod/antenna.

Finally, the ARTS-700 features an antenna connection with a 1W maximum that can be used to connect for over-the-air (OTA) testing. OTA testing is a method of predicting the performance and reliability of a wireless device under real-world conditions. The device is placed in a free space environment and subjected to different test conditions to ensure that it performs as expected.
