Overview
The Eye in the Sky helicopter kit by Kaelin Aero enlarges the cabin floor window by 350% to provide substantially improved vertical visibility for critical operations. The solution is designed to enhance pilot sightlines without significant weight or aerodynamic penalty and is certified via EASA STC.

Design & Development
Developed by Kaelin Aero under EASA STC, the modification increases the cabin floor glazing and adds enlarged glazing on the pilot's side to provide an unrestricted view of key mission areas. The kit is supplied as a plug-and-play package and installs without structural changes while retaining the original pilot door.

Key features

• Increases cabin floor window area by 350%
• Compatible with AS350 / H125 helicopter series
• Enlarged glazing on pilot side and cabin floor to expand pilot field of vision
• Delivered as plug-and-play; no structural modifications required
• Original pilot door retained
• EASA STC certified modification

Materials & Construction
The primary structural element is a carbon-fiber composite engineered to improve visibility while minimising added weight and aerodynamic impact. A lightweight aluminium cover provides access; it is designed for easy opening and stowage.

Installation & Maintenance
Typical on-site installation time is approximately 1.5 days. The kit is intended for installation by experienced aircraft mechanics with standard tools and allows straightforward removal if required. No additional certification is required beyond the supplied EASA STC when installed as specified.

Operational advantages
The expanded vertical field of view provides operational benefits for rescue missions, mountain landings and precision external load operations, improving safety margins, situational awareness and mission efficiency.
