A Game-Changing Electric Aviation Plan | David Stepanek


Listen Later

Bristow’s Chief Transformation Officer David Stepanek returns to Hangar X to share real-world lessons from one of the most credible electric aviation test programs today: commercial-style operations in Norway using BETA Technologies’ all-electric ALIA (CX). Rather than focusing on limitations, David explains Bristow’s pragmatic “crawl–walk–run” approach—starting with conventional electric flight, validating operations, maintenance, charging, and safety processes, then scaling toward hybrid-electric and uncrewed offshore cargo missions.
From Stavanger–Bergen flights across fjords to battery-cycle data, tire wear realities, and an unexpected EMI/radio-communication issue that prompted a full safety review, this episode offers a grounded look at what it takes to make advanced air mobility commercially viable—without outrunning aviation safety systems.

Episode highlights
• Bristow’s “focus on what electric aircraft can do” approach to building early profitable markets
• Why Norway is an ideal launchpad (geography, infrastructure, public-sector alignment)
• Learnings from ~86 flights and ~125 charge cycles on BETA’s ALIA
• Charging time, range planning, and real operating economics (energy cost per leg)
• The real-world EMI/radio issue—and how it was handled through rigorous safety processes
• Why cargo-first and offshore logistics are the near-term commercial wedge
• The case for hybrid-electric as a bridge to longer range, higher payload, and reduced infrastructure dependency
