Overview
Portside provides a cloud-based suite of applications for business aviation operations. The core Portside Platform integrates with most aviation systems to gather real-time data and offers dashboards, reports, and automated workflows via a subscription-based cloud service that can be tailored to a flight department’s size. It differentiates itself by offering broad system integration plus modules for expenses, safety management, and flight management, and it has expanded its capabilities through acquisitions of Baldwin Safety & Compliance and Avianis. The goal is to give flight departments a single, data-driven platform to oversee operations, cut costs, and improve efficiency and safety.
