Flight Management System 飞行管理系统
A dual Flight Management System (FMS) is installed. The FMS-5000 is a satellite-based navigation system that provides the capability of en route, terminal, and non-precision approach lateral navigation. The FMS is able to load information from, and download to a standard laptop via the File Server Unit (FSU). Major functions of the FMS include:

•Fully coupled lateral and vertical navigation (with interface to the flight director)
•Flight planning (with worldwide database)
•Blended radio navigation (GPS, VOR, DME,etc.)
•Remote radio tuning.

The system includes two CDU-3000 Control Display Units in the pedestal, two Global Positionning System GPS-4000A receivers and two Flight Management Computers FMC-5000 in the IAPS.

The Course Panel is mounted in the center pedestal and provides control knobs to select desired heading and course.

Integrated Flight Instrument System 综合飞行仪表系统
The IFIS system comprises a single File Server Unit (FSU) and dual Cursor Control Panels (CCPs) and presents Airfield Electronic Charts on the MFDs. It is also capable of displaying Enhanced Map Overlays and Graphical Weather on the MFDs, when these options are selected. The IFIS also provides data load capability via an Ethernet port for use with any standard laptop.

The IFIS supports Chartlink, which allows automatic loading of FMS Flight Plan Charts and display of aircraft position on geo-referenced Airfield Charts.

Weather Radar System 气象雷达系统
The Weather Radar System (WXR-840) detects wet precipitation ahead of the aircraft. The radar scan arc is the aircraft's heading angle ±60 degrees. The radar sends weather data to each navigation display and Multi-Function Display (MFD). Each pilot can select radar mode, range, tilt angle and gain separately on their display, effectively providing two completely independent weather displays from a single radar.
