US low-cost carrier (LCC) Southwest Airlines has contracted Honeywell Aerospace to retrofit a suite of avionics systems on its fleet of 737NG aircraft, as well as supply the equipment for the 30 737 MAX aircraft it has on order.

Honeywell Aerospace is to provide safety, communication and navigation systems, including its new Integrated Multi-Mode Receiver (IMMR), which the OEM says is the industry’s first “all-digital navigation receiver that integrates multiple regulatory requirements into a single receiver”.

Southwest is the first airline to install the IMMR, which Honeywell claims will offer a 50 per cent weight saving compared with current solutions.

Other upgrades will include Honeywell’s SmartTraffic traffic collision avoidance system, its IntuVue RDR-4000 3D weather radar and its Aspire satellite communications system.

According to Southwest Airlines the upgrades will ensure its aircraft meet upcoming “NextGen” navigation and communication regulations from the FAA.
