The background story on the StandardAero/Thales industry-first four-axis autopilot for light helicopters

What was the initial concept behind this compact autopilot solution?

This project is part of StandardAero’s SAFECRAFT portfolio, aimed at reducing pilot workload and enhancing flight safety. Our discussions with Thales began in 2015, leveraging:

• StandardAero’s expertise in aircraft modifications and Supplemental Type Certifications (STC)
• Thales’ proven compact autopilot technology

The goal was to create an affordable, lightweight solution to improve helicopter safety and performance.

Between 2016 and 2017, nearly 250 lives were lost in 200 helicopter accidents, mostly due to pilots losing control. Addressing this risk was a key driver for this innovation.

Why is there an urgent need for this technology?

Light helicopter flight profiles are inherently demanding. Pilots often operate in dynamic environments, facing challenges like:

• Poor weather conditions (fog, rain, low visibility)
• Urban obstacles (buildings, power lines)
• Complex missions (tourism, rescue, law enforcement)

Tragic accidents reinforced the need for automated flight stability solutions:

• 2019 Hawaii crash: Seven casualties, including children, due to low visibility conditions
• 2020 Kobe Bryant crash: CFIT (Controlled Flight into Terrain) incident in dense fog
• 2020 French Alps rescue helicopter crash: Five casualties in poor weather conditions

What does the new autopilot system offer?

This four-axis autopilot significantly enhances flight stability by providing:

• Smoother flight dynamics, acting like a shock absorber in turbulence
• Automatic recovery to a safe altitude and orientation in low visibility (fog, smoke)
• Compact architecture, with flight computers embedded within the actuators, reducing installation complexity and downtime.

Why partner with Thales?

Before launching the project, we surveyed helicopter operators to identify gaps in the market. The key feedback was a need for:

• A purpose-built helicopter autopilot (not adapted from fixed-wing solutions)
• Easy installation and operation
• A balance between high performance and affordability

Thales’ solution met all these criteria. With over 1,200 STCs, StandardAero’s expertise in certification and modification made this partnership a natural fit.

Additionally, both companies have global support networks, ensuring reliable aftermarket service.

What are the next steps?

StandardAero and Thales are currently conducting extensive flight tests with WeatherTech as the launch customer.

Key milestones include:

• FAA STC approval by mid-2021
• Market availability by Q3 2021
• Further certifications for expanded market adoption

This solution aims to increase helicopter stability, reduce wear and tear, and most importantly, enhance flight safety to prevent future accidents.
