Cockpit modification on a B737-200 aircraft

The Requirement

This B737-200 operator, flying charter and remote community services in the Canadian North, wanted to upgrade obsolete avionics to improve safety, reliability and increase efficiency. This aircraft lands at both standard airports and unimproved fields.

Why the Operator Selected MC2

This aircraft “workhorse of the north” needed Mid-Canada Mod Center’s (MC2) skills and knowledge to rapidly ensure the aircraft was flight-ready. MC2’s full-service approach, from concept, to component and equipment sales to project specs, installation and certification meant the aircraft was ready for wheels-up on an extremely tight timeline

Main Benefit

Improved safety and efficiency are key to this modification. The mods also extend the life of the aircraft.

About the Mods

Like every project MC2 undertakes, the modifications can be complex. This Canadian based charter and cargo operator’s aircraft was no exception. While the existing radios, audio systems, original Flight Management System (FMS), EGPWS and weather radar were retained, key upgrades included:

  • Four (4) Universal Avionics EFI-890R ADF (Advanced Flight Displays): replaced the aircraft’s existing and now obsolete legacy HSI/ADI suite with large format, flat panel integrated smart displays and associated control panels. The AFDs incorporated into this cockpit upgrade offer flexibility as a stand-alone Primary Flight Display (PFD) or Multi-Function Display (MFD). The 8.9” (diagonal) LCD displays are high-resolution and high-contrast that provide superior readability through the full range of ambient lighting conditions from bright sunlight to dim nighttime environments, with extremely wide viewing angles. In addition, the system is backlit, has reduced power requirements and produces a lower unit operating temperature for increased reliability.
  • Dual Honeywell Laseref IRS (Inertial Reference Sensors): replaced the existing vertical and directional gyros which were removed.  The IRS Dual Honeywell Laseref Inertial Reference Sensors were installed and interfaced to both the new and existing systems.
  • A second UNS-1LW SBAS FMS (Flight Management System): was also installed to supplement the existing UNS-1LW system previously installed by MC2.

Great Results

The resulting upgrades and modernization give this charter and cargo operator new, large format, integrated smart displays connected to the existing autopilot and flight directors to provide accurate and reliable sources of heading and attitude with reversionary display capability. Better flight management, modern messaging capabilities, also improve safety and efficiency on this B737-200 Combi.

What the Operator Says

“We had an extremely tight timeline for these avionics upgrades. It’s always difficult to have an aircraft out of service, but MC2’s expertise and full-service approach to these mods, helped us achieve increased safety and new efficiencies as well as improved reliability.”
