A cabin of class

The CJ4 cabin introduces a new level of luxury and technology to the CJ line.

Cabin environment

The CJ4 features an attractive width of 58 inches, enhancing its cabin comfort.

The CJ4 features separate temperature-control zones for the cockpit and cabin, and digitally managed pressurization that maintains a sea-level cabin up to an altitude of 21,067 feet. Passengers can also enjoy an exceptionally quiet cabin via acoustic-blanket soundproofing.

Dual-zone temperature control
Digitally controlled pressurization
Long-lasting LED lighting

In-cabin technology

Introducing the award-winning VenueTM HD integrated cabin management and entertainment suite. Venue provides high-definition digital video and audio for in-flight entertainment or business. Connect your laptop and have a working session. Or relax during your flight with your choice of CDs, Blu-ray DVDs, and games.

Seating and configuration

Six deeply cushioned, generously wide reclining leather seats feature a patented retractable armrest design, with available lumbar support and seat-side media docks. Each seat tracks forward, aft, and laterally and may recline all the way to horizontal in certain configurations.

The standard configuration for the CJ4 cabin is six-place center club seating, with a seventh seat across from the entry door. Another floor plan configuration offers a two-place side-facing couch for a total of nine seats. Lockable external baggage compartments can be loaded with a massive 1,000 pounds of total weight.

Operation: Best-in-class flight deck

Mission accomplished

The CJ4’s avionics suite combines category-leading technology with ergonomic enhancements and extreme user friendliness. Our engineers designed the CJ4 flight deck, powered by Collins Pro Line 21, from extensive research into how pilots interface with technology. The result is improved piloting with simple operations and significantly reduced workload. With the flight deck’s tilted control panel, illuminated push buttons replacing toggle switches, the ramped pedestal, and every flight instrument placed within the pilot’s field of vision, the environment is designed carefully around the work that is required. Electrically heated windshields and side windows keep the pilot in complete quiet as well, reducing distractions.

Navigating weather

A standard CJ4 capability is enhanced weather tracking via the MultiScan™ RTA-4112 Weather Radar system. Pilots can use this solid-state color radar system to detect weather systems and navigate around them to minimize turbulence. Short-, mid-, and long-range weather detection is included with multiple radar scans at preselected tilt angles. At any altitude or range, the system displays an optimized weather picture for the pilot.

The system’s true 320-nautical-mile “clutter-free” weather display detects weather-related threats at any location in the world. The accurate depiction of weather and turbulence hazards significantly reduces pilot workload and training. The system also supports integration of new data sources as they become available.

Key features include:

      • Fully automatic operation
      • Clutter-free, real-time weather detection from the aircraft nose to 320 nautical miles
      • Variable temperature-based gain
      • OverFlight™ protection
      • Geographic Weather Correlation (patented)
      • Certified turbulence detection
      • Enhanced ground-clutter suppression
      • TrueZero™ automatic antenna-misalignment compensation
      • Path attenuation compensation (PAC) and PAC alert
      • SmartScan™ rapid update technology
      • Exceptional transmitter/receiver system performance
      • Active gain in all modes
      • Full split-function operation
      • High reliability

Proximity awareness

An available optional capability for the CJ4 is the MARK V Enhanced Ground Proximity Warning System (EGPWS), by Honeywell, which protects against wind shear and controlled flight into terrain (CFIT). The pilot can input a variety of aircraft parameters and the system will apply algorithms to calculate an alerting envelope around the aircraft. When parameters are exceeded, the system will alert the flight crew with text messages on the displays, as well as audible alerts when necessary.

The system offers pin-selectable altitude callouts, envelope modulation, geometric altitude algorithm, turn extrapolation, auto-display pop-up, auto-tilt of weather radar, and the ability to host Honeywell’s Runway Awareness and Advisory System. Warnings include:

  • Excessive descent rate
  • Terrain closure rate
  • Excessive altitude loss after takeoff or missed approach procedure
  • Insufficient terrain clearance
  • Descent below glideslope
  • Excessive bank angle
