Case Study: Designing Large Area Display with ARINC 818-2 IP Core


Since the last decade, the trend in aviation cockpit design has been to increase display area while decreasing the number of individual displays.

It led to the development of Large Area Display (LAD), which integrates flight and mission-specific data on a single, smart, redundant screen. A Large Area Display (LAD) provides the pilot with next-generation visual cues and situational awareness.

iWave assists cockpit display manufacturers in the development of Large Area Displays by incorporating a customized ARINC 818 IP Core into their design.


The client wanted to build a Large Area Display that features a 20-inch x 8-inch active area with multi-touch screen technology. An ARINC 818 protocol conversion COTS module was thus required, which was capable of splitting a single ARINC 818-2 data stream into two and displaying them simultaneously on the screen. In order to shorten the time to market and accelerate product design, the customer was looking for an enterprise with experience in avionics and ARINC 818 protocol-based products.

System Design and Implementation

To meet the requirement, the display was incorporated with two iWave-designed ARINC 818-2 receiver modules. These modules are designed in such a way that they can split or divide a single ARINC 818-2 stream into two and dynamically display them on the screen. (For example, a video with a resolution of 2560 x 1024 will be split and displayed as two separate 1280 x 1024 display screens.)

A switch is incorporated to restrict the number of channels and content to be displayed on the screen. When the switch position is set to zero, the ARINC818-2 receiver acts like a normal receiver, receiving two different ICDs and displaying the same. When the switch is set to one, only one channel is active, and the receiver displays the content received via that channel. To fit with a low-profile Head-Up Display, the LAD is customized with a variety of configurations of push buttons and switches.
