The Thales / StandardAero StableLight 4-axis autopilot brings advanced stability augmentation and inadvertent-IMC recovery to your AS350 / H125 — reducing single-pilot workload for HEMS, law enforcement, utility, corporate and business operators, and tour fleets, particularly in single-pilot night and inadvertent-IMC scenarios. FAA STC approved. Sold and installed at Precision Aircraft Services (Peachtree City, Georgia) — an authorized dealer and installation facility for the StableLight system.
StableLight is a stability-augmentation and inadvertent-IMC recovery system for VFR aircraft. It is not an IFR certification.
Built specifically for the AS350 / H125 by Thales — drawing on the flight-control heritage Thales developed for Airbus' larger civil rotorcraft, miniaturized and adapted for a light single. Sold and installed by Precision Aircraft Services, an authorized dealer and installation facility.
Single-pilot night and inadvertent-IMC operations are the highest-risk regime in the rotorcraft industry. StableLight directly addresses what FAA HEMS rules and the NTSB safety record have been pushing toward: redundant stabilization that keeps the aircraft flying when situational awareness fails.
Auto-hover for hoist, longline, and night NVG ops. Lighter pilot workload for HEMS, law-enforcement surveillance and pursuit, and corporate and business owner-flown missions — a stabilized hands-off platform that meaningfully reduces fatigue and improves precision across the missions you already fly.
An AS350/H125 with StableLight commands a meaningful premium on the resale market, strengthens your position in pilot-warranty and underwriting conversations, and helps you attract and retain experienced pilots in a market where good ones are scarce. The retrofit pays back faster than most operators expect.
StableLight is purpose-built for the AS350 / H125 family. It's not a kit-bashed retrofit — it's a clean-sheet system, drawing on Thales' flight-control heritage from larger Airbus civil rotorcraft and adapted for a light single. Sold and installed at Precision Aircraft Services, an authorized dealer and installation facility.
Thales' breakthrough in compact-actuator design is what makes 4-axis autopilot finally practical on a light helicopter. The actuators carry their own electronics — no separate flight-control computers — bringing the kind of autopilot architecture Thales developed for the big Airbus civil rotorcraft down to a single-engine platform.
Indicative specifications. Final installation details determined per airframe configuration and operator avionics stack.
| Eligible airframes | Airbus AS350 B2 / B3 / B3e (H125). EC130 family currently not certified — contact us for status. |
|---|---|
| Operating envelope | VFR (day / night). StableLight is a stability-augmentation and inadvertent-IMC recovery system; it does not change the aircraft's certification basis or confer IFR capability. |

| Modes | Stability augmentation, attitude retention, auto-trim, stabilized climb, auto-hover, inadvertent-IMC attitude recovery, TAWS-coupled auto pull-up, coupled go-around mode |
| Approval basis | FAA Supplemental Type Certificate (STC). Additional approvals per Thales / StandardAero (see current training materials). EASA validation in progress. |
| Key technology | Thales SMART linear actuators with integrated electronics — eliminates separate flight-control computers |
| Avionics compatibility | Modern Garmin certified rotorcraft stacks (G500H TXi, GTN 750Xi / 650Xi, GFC 600H). Other configurations evaluated case-by-case. |
| Pilot training | Initial differences training included with installation. Most pilots transition in a single training flight. |

No. StableLight is a stability-augmentation and inadvertent-IMC recovery system. It does not change the aircraft's certification basis. IFR certification of a helicopter requires a full set of instrument-flight systems, redundancy, lighting, pitot-static, and certification work that extends well beyond an autopilot retrofit. The AS350 / H125 remains a VFR-only aircraft after the StableLight installation. What StableLight does deliver is a meaningful reduction in single-pilot workload and a recovery path if a pilot encounters IMC unintentionally — addressing the highest-risk regime in the NTSB safety record for light single-engine rotorcraft.
If you fly an AS350 B2, B3, or B3e (H125), the answer is almost certainly yes — the FAA STC covers the family. The few exceptions tend to involve unusual mission-equipment interference. Send us your N-number and we'll confirm in 24 hours.
Not yet. The current FAA STC covers the AS350 / H125 family. EC130 (B4 and T2) certification is on the Thales / StandardAero roadmap. If you operate EC130s and want to be notified when EC130 certification is announced, fill out the form and we'll add you to the early-access list.
Typical downtime at the PAS Part 145 facility is roughly two to three weeks from arrival to release-to-service, including the post-install flight-test card. We schedule installs to align with calendar inspections wherever possible to minimize total time off-line.
Pricing varies meaningfully by avionics stack and airframe configuration. We don't post a sticker price because the honest answer depends on what's already installed. Submit your tail number and we'll send a written quote, usually within two business days.
Yes — StableLight integrates cleanly with the modern Garmin certified rotorcraft stack. We've also evaluated alternative installations on a case-by-case basis. Tell us your existing panel in the notes field and we'll confirm compatibility before quoting.
StableLight gives operators a stronger position when discussing pilot warranty terms, mission profile, and risk with their underwriter — particularly for HEMS, law enforcement, and corporate operations. We don't quote specific premium reductions; that's a conversation between you and your broker. On the resale side, AS350s with a 4-axis autopilot retrofit trade at a premium versus unequipped airframes.
Initial differences training is included with the install package. Most pilots transition comfortably in a single flight session. Recurrent and instructor-rated programs are available through our training network.
Yes — Precision Aviation Group has long-standing relationships with multiple aviation finance partners offering retrofit-specific financing. We can structure terms to align with your existing aircraft note.
