C-40 Cockpit Indicator 411


Onboard Systems is rolling out our C-40 Cockpit Indicator across multiple aircraft and Onboard Weighing System kits. The C-40 indicator offers simplified hook TBO tracking, improved LCD screen contrast, and a digital weight reading with an analog bar display, among many other improvements over the current C-39 indicator, which has been in use for more than twenty years. A forthcoming data logging software upgrade will allow operators to record time, load weight, and GPS coordinates for pick-up and drop-off locations. Software upgrades can be downloaded from the Onboard Systems website onto a thumb drive for fast and easy field installation.

The C-40 indicator is upgrade-compatible from the C-39, so operators with existing equipment who would like to take advantage of the advanced features provided by the C-40 can simply replace their C-39 unit with a C-40 unit as their load weigh kit(s) become certified for use. Please contact us for more information.
