Vertical Power
This brand new power management system harnesses CPU power to eliminate the need for much of an aircrafts wiring by consolidating major electrical functions into a single box. It comprises three units: a display, controller module/panel housing and mag controller. Bundled into the setup are radios, instruments (including GPS, EFIS and engine monitoring) and lights. Each flight phase is broken down into the tasks normally performed manually by the pilot, and the VP-200 addresses them more or less automatically, while also providing override capability in the event of a system failure.
