    NEW SOUNDS FROM THE REAL AIRCRAFT

  • New 3D mix for the external aircraft sounds

  • New starter sounds
  • New autopilot/yaw damper disengage alert
  • New cabin altitude alert
  • New overspeed horn alert
  • Pitch trim sound (stabilizer in motion)
  • Stick shaker sound
  • Brake sounds (“birds in the cockpit”)

    MODIFICATIONS AND IMPROVEMENTS

  • Revised flight model for better performance during takeoff and climb, more stability in cruise at high altitude, and to eliminate unwanted roll/yaw oscillations at altitude (pilot tested)
  • New weight and balance to conform better to the real GLJ Model 25D
  • New flight director annunciators, conform to the real aircraft
  • Antiskid lights illuminate like on the real aircraft (only when antiskid inop or during test or malfunction)
  • Steer lock switch is now spring loaded and conform to the real aircraft. Release button added on yoke. Green annunciator goes on when steering is engaged.
  • Nose pitches down when spoilers are deployed, like on the real aircraft
  • New cabin altitude alert and horn (annunciator flashes above 9,000 ft., horn blows above 10,100 ft.)
  • Low fuel annunciator modified to conform to the new fuel system
  • Enhanced emergency gear extension system with air bottle (rechargeable)
  • Enhanced stall warning system with functional test switches
  • CPCS rate knob now a rotary-type design, no longer spring loaded
  • Engines up to 85% RPM in reverse (thrust reversers deployed), like on the real aircraft
  • New calibrated cabin altitude controller (no more pressurization issues above FL400)
  • Emergency battery switches no longer linked to the antiskid system (emergency batteries are now simulated)
  • No more standby gyro power switch, instrument now powered by main bus or by emergency batteries
  • Wing and horizontal stabilizer anti-ice system fully simulated, new wing temperature gauge
  • DME hold mode now temporarily holds the last reading on the DME head display
  • Thrust reversers cannot be armed it the aircraft is not on the ground or if the throttles are not at idle, to prevent accidental extension of the thrust reversers while in flight
  • Minor modifications on both ADIs and HSIs
  • Several minor system improvements
  • Several modifications on textures
  • "Remove Before Flight" items are no longer installed by default when power is turned off (user controlled)
  • Crew's presence in the cockpit is now user controlled
  • Sound volume and balance can now be adjusted by moving cursors on the 8-track tape player (volume only on the FSX version)
  • Engine oil pressure gauge now needs AC power to function
  • Default autopilot vertical speed (when engaged) is now set to 1,000 ft./min.
  • Red and white speed/Mach bugs on the ASI now allow for better fine tuning of the selected airspeed

    UPDATED MANUAL

  • New comprehensive 20 Series fuel system section
  • New comprehensive AFCS (autopilot)/FD section
  • New climb and cruise tables in the planning section
  • Images and text revised and updated, with new content
  • 220 pages (to this date)
  • Normal and emergency procedures sections are now available in French (30 pages)

    Fixes, modifications, improvements and new features are subject to change without notice. Some functionalities may differ from those in the real aircraft due to limitations in the simulation platforms. Some features available in the native Prepar3D® versions may not be available in the FSX version. The FSX version contains less animations and features than the native Prepar3D® versions. However, systems and procedures are the same on all platforms and this has no impact on the simulation.

    Due to the high number of animations in the virtual cockpit and until further notice, the native Prepar3D® versions require the OPTIMIZE_PARTS=0 entry in the "Prepar3D.cfg" configuration file. This is an undocumented simulator issue, not an addon issue, and it will be fixed in the upcoming release of Prepar3D® v4.1 currently in its beta phase.
