Long before GNSS-based navigation became mainstream, Corporation Logic Air Inc., a Montreal-based Approved Maintenance Organization (AMO), embarked on a mission to empower northern and regional operators with advanced Localizer Performance with Vertical Guidance (LPV) capability — redefining access and safety standards for remote communities across Canada.

At that time, most northern airstrips were limited to non-precision approaches, often forcing pilots to divert due to poor visibility or the absence of ground-based navigation aids. Recognizing this challenge early on, Logic Air's avionics and certification team collaborated closely with aircraft operators and regulators to introduce LPV-enabled flight operations long before it became the global standard.

"It was a frugal and innovative engineering effort — what we often call Jugaad in India — born from necessity," recalls Prashanth Rajanna, Director – Strategy & Business Development at Logic Air. "There was no forward-fit or OEM-supported LPV solution for these aircraft. Our team convinced avionics suppliers like CMC Electronics to provide GPS systems and developed the interface units and integration pathways that could be certified under Transport Canada. That became a turning point for many operators in the North."

Transforming Northern Operations

• Pioneered LPV integration on legacy aircraft serving northern routes, well before widespread adoption.
• Partnered with CMC Electronics and regulators to validate the first retrofit STC for LPV operations in Canada in 2011.
• Enabled reliable, all-weather access to remote communities where ILS procedures were not available.
• Established the technical foundation for future GNSS and PBN programs that underpin Canada's navigation infrastructure today.

With more than 150 successful LPV STC implementations across the Boeing 737 Classic and NG fleets worldwide, Logic Air has become a trusted integrator of precision-navigation upgrades.

This milestone cemented Logic Air's reputation as a trailblazer in avionics innovation — bridging operational gaps through ingenuity, collaboration, and persistence. It showcased the company's enduring commitment to improving northern accessibility, flight safety, and environmental sustainability through precision-based navigation.

Leveraging the B737 Platform – From Civil to Defence Applications

With more than 150 successful LPV STC implementations across the Boeing 737 Classic and NG fleets worldwide, Logic Air has become a trusted integrator of precision-navigation upgrades.

Today, the company is extending this proven capability to the defence sector, exploring opportunities to support the Boeing P-8 Poseidon — the Indian Navy's long-range maritime patrol aircraft — which is built on the same B737 NG platform.

"By applying certified STC-based architectures and avionics integration expertise, we can help enhance mission precision, approach safety, and navigational resilience in complex maritime environments."

The Boeing P-8A Poseidon, derived from the commercial 737-800NG airframe, represents one of the most successful examples of a civil-to-military platform adaptation in modern aerospace. Although externally reinforced and mission-equipped for maritime patrol, reconnaissance, and anti-submarine warfare, the aircraft retains a remarkable degree of avionics and systems commonality with its civil predecessor — a factor that has been central to its cost efficiency, certification maturity, and ease of fleet integration.

Core Avionics Architecture

At the heart of both platforms lies the Next-Generation (NG) flight deck, built around the Honeywell-supplied integrated avionics suite. This architecture encompasses:

• Dual Flight Management Computers (FMCs) and dual GPS/IRS navigation systemsproviding robust redundancy
• A shared digital flight control system (DFCS) and autopilot/flight director logic, adapted in the P-8 for low-altitude maritime operations and mission profiles.
• The same ARINC 429/629 data bus framework, allowing seamless integration of mission-specific subsystems without altering the base flight deck logic.

This alignment opens avenues for collaboration with OEMs, system suppliers, and naval aviation authorities, particularly as India continues to strengthen its maritime reconnaissance and surveillance capabilities. Logic Air's proven retrofit methodologies and deep understanding of global certification processes position it as a credible partner for both civil and military modernisation programmes.
