QCM Design has successfully developed and engineered another EASA Supplemental Type Certificate (STC) for the retrofit of Collins Aerospace’s IRT NX SATCOM solution on King Air B200 / B300.

This project was completed in partnership with Danish MRO, DAO Aviation AS, an EASA Part 145 specializing in base & line maintenance on Beech King Air series (alongside many other aircraft types), whose experienced technicians completed the installation in accordance with our specifications.

This STC approval is the second of its kind received by QCM Design, the first being for Cessna CJ Series, completed in April 2024. The STC for the retrofit of Collins’ IRT NX solution on Cessna Citation XLS/+ is expected to be completed this year.

The Connectivity Solution

Collins’ Iridium Certus SATCOM Solution

The IRT NX SATCOM system from Collins Aerospace accesses the Iridium Certus® 700 network, which offers reliable, weather-resistant connectivity worldwide.

This SATCOM system includes a data unit, configuration module and antenna, which provides consistent, cohesive connectivity throughout the aircraft while using less power than legacy systems.

This solution was designed with the modern business professional in mind. Its high-speed, weather-resistant cabin connectivity through the Iridium Certus® 700 satellite service enables voice calls, sending and receiving e-mails and messages, browsing the internet and scrolling or posting on social media throughout the flight, while its light weight and compact size means it can be installed on most aircraft types, including smaller business jets.

Advantages of this connectivity solution:

• Affordable connectivity solution
• Applicable to business jets of any size and category, even smaller ones, due to Low Size Weight and Power (SWaP) terminals
• High speed (704 kbps), weather-resilient L-band connectivity
• Pole-to-Pole coverage at any altitude – not restricted to one geographic area
• Low Latency, resulting in faster connections
• Lower weight, drag and power usage than other solutions
• Already certified and deployed, whereas other solutions are still in the design and testing phase

You can view the certificate of the STC here: QCM STC 10085594 Certification for Collins Iridium Certus SATCOM Installation. This STC is valid for all aircraft in the B200 / B300 series.
