Cockpit floor window built for visibility, safety, and efficiency.

Developed in close cooperation with pilots and mechanics from other entities of Swiss Helicopter Group, this product combines a redesigned right-hand floor edge, new lower cowling window, delivering maximum visibility, improved safety, and effortless transition between aerial work and passenger transport.

Maximised visibility

The new floor window guarantees optimal visibility to the pilot.

Easy installation

Any Part 145 is able to install the kit. Nonetheless specialised support is also available.

Competitive price

Swiss made product with outstanding performance at an affordable cost and shipped in an optimized package fitting the standard pallet size. Fleet discount is available.

No operating limitations

No airspeed limitation, no ground use limitation, modified floor edge qualified for 270kg abuse loads.

How the cockpit floor window works

The problem

In aerial work, the pilot’s visibility is essential for accurate positioning, sling release, and firefighting precision.

Blind point created by the RH floor edge and floor structure represents a constrain to increase pilot visibility.

The solution

Our engineering team modified the helicopter structure. The right-hand floor edge and lateral frames were modified to reduce the visibility obstructions, offering a larger and safer field of view without compromising strength.

The extra advantage

Beyond visibility, this design introduces true operational flexibility: the pilot can reconfigure the aircraft for passenger missions in seconds — with a one-hand gesture.
This means less downtime, easier boarding, and a cleaner, safer cockpit layout for every mission.

Cockpit Floor Window – Frequently Asked Questions

Is the modified cockpit floor edge fully walkable?

Yes. Structural integrity is maintained, and the edge has been tested for 270kg abuse load.

Why modifying existing lower cowling for the cutout instead of providing a new one?

You will not run into compliance issues or other troubles if your existing lower cowling has already other modifications retrofitted like additional landing lights, antennas etc.

Afterwards this variant reduces the size of the shipping kit and with this also shipping costs.

Isn't it the same floor window like from other vendors?

The Swiss Helicopter Floor Window is an unique product and only offered by Swiss Helicopter Engineering and its distributors.

Compared to similar products it offers currently the largest cutout and unique features like the foldable boarding step.

Can I use the AH Canada High Visibility Door with this modification?

Yes. The design is fully compatible with both the TC holder’s original right-hand door and AH Canada’s High Visibility Door.

Is the Cockpit Floor Window applicable with RH sliding door configuration?

Not yet, but it's under investigation in Summer 2026 to serve this option as well.

Is the Cockpit Floor Winodw also applicable for older models like B2/B1/B/BA?

We are currently (2026) working on a compatibility extension for older models due to minor differences of the floor depending on series generation.

Nevertheless, don't hesitate to contact us for a quote. In any case, a compatibility check of the configuration is performed in advance for every non-binding quote.

Is the Cockpit Floor Window suitable for existing helicopter floor windows?

Yes. It can be retrofitted to aircraft already equipped with common floor window solutions.

How long does Cockpit Floor Window installation take?

Typically around 4 working days, depending on MRO environment and aircraft configuration.

What documents are provided with the kit?

STC, Installation Manual, Flight Manual Supplement, Instructions for Continued Airworthiness and kit supplied with EASA Form1.

What’s the price?

The base kit is 25,000 CHF, with an optional full-cover kit available for 2,000 CHF. Installation costs vary by operator.
