List of features and bug fixes

Version 2018.1

• New images for the new splash screen and thumbnails system
• FDM improvements:
  • Fixed deflection angles of ailerons and roll moment due to ailerons
  • Added spiraling propwash effect (requiring right rudder at full throttle, low airspeed)
  • Made the elevator action at high AoA asymmetric in order to take into account the screening effect of the horizontal stabilizer in such stall conditions
  • Increasing the side force due to rudder, to make it consistent with the exerted moment
  • Decreasing the adverse yaw (the aileron trim gave too much slip-skid-ball deviation at cruise)
• Increased maximum rotation of yoke from 70 to 90 degrees
• Use shift + q to reset view
• Added avionics sound
• Fixed bug with oil temperature and pressure gauges (they were not working when complex engine procedures was toggled off)
• Fixed bug with lighting of pontoon wake effect
• Eliminated wingtip and tail sparks when over water
• Eliminated sparks of broken gear while aircrafts sits on the flight deck of a moving carrier
• Fixed some bugs with the walker

Version 2017.1

• Control surfaces can be checked for free movement during preflight inspection
• The opening of the baggage dialog was delayed as to wait for the animation of the baggage door
• Cleaning up the Aircraft Options dialog
• Improvements to the Ground Equipment dialog
• Callsigns of new users are automatically randomized to avoid them blocking other new users on multiplayer
• New About This Aircraft dialog, with information about the project as well as relevant links
• The pilot's yoke can now be locked with a control lock (lock can be found in the bag on the left of the pilot's seat)
• Fix bug with ADF timer in the radio stack
• Added view for IFR training
• Improvements to the carburetor system (icing, carb heat)
• Improvements to the engine coughs (due to fuel contamination or carb ice)
• Lowered limit of critical oil level according to Lycoming's manual
• Critical oil will not cause the engine to cough, it will simply quit when oil reaches the critical value of 2 quarts
• Improved fuel contamination system (fixed some bugs)
• More realistic bush wheels and tires
• Fuselage shows fresnel effect

Version 2016.4

• Improvements to the oil management (better function, oil now changes CG and weight of the plane, etc.)
• New ALS external view navigation, taxi and landing lights
• Added fire extinguisher and ELT models
• Bug fix for flashlight effect not illuminating the baggages
• Bug fix for interaction with external items in one of the tutorials
• Improvements to the autostart function

Version 2016.3

• Radio stack has been reworked (textures, 3D model)
• Radio stack illumination has been vastly improved and includes a daylight mode now (via RADIO LT at 0%)
• Fix bug with airspeed indicator
• Fix bug with the 3D model of the key in the ignition
• Fix bug which allowed to click on external hotspots while inside the cockpit
• Better autostart function, should work under more situations and warns the user if the engine fails to start
• The tooltip of the primer lever now shows the number of strokes
• Clock now displays local time
• Fix bug with battery: voltage now drains normally
• Add battery options and recharge button to aircraft menu
• Improved yoke model
• New splash screen no. 1
• Add ground equipment like safety pylons, ladder, fuel tank trailer, and ground power unit

Version 2016.2

• Decreased rudder authority
• Added propwash effect for 180 HP version
• Improvements to the irradiance effect
• Better oil dialog
• Flap lever is now dragable and scrollable
• Added normal map to wheels and other objects
• Improvements to the heading indicator
• Correct rudder pedal animation
• Updated tutorial to Barcelona
• Changed "Autostart" menu item to actually start the engine as well
• Split instrument light knob into a knob that two knobs: one that controls the instruments, and one that controls the radio's

Version 2016.1

• Ski's
• Amphibious plane improvements:
  • Added two metal reinforcement bars in the cockpit
  • Added panel for gear deploy and retract
  • Added water rudders retraction mechanism
• Saving state of switches is now optional
• Zooming with mouse scroll wheel in Helicopter View, Model View, and Walker Orbit View
• Additional views for co-pilot and passengers
• New sounds:
  • Rain (ambient and windshield) and thunderstorms
  • Wing damage
  • Wheel damage
• Windshield rain overhaul
• Opening the baggage door displays a window which allows weight to be added. Baggage will be displayed if the weight is high enough
• ASI now shows the IAS instead of the CAS
• Adjusted stall horn volume to sound to about 5-10 knots above stall speed
• Carburetor heat toggle now drops RPM as expected
• Oil consumption and management have been implemented
• Refactored fog/frost system: air flow now depends on airspeed and engine RPM. Supports overhead air vents, windows, and doors. Humans add extra heat and humidity.
• Preflight inspection improvements:
  • Added "Preflight Inspection" checklists and tutorial
  • Pitot tube can be clicked to add/remove a red "remove before flight" label
  • Nose wheel can be clicked to add/remove chocks
  • You can tie down the wings and tail to the ground. It will hold the aircraft even with full engine power.
  • Each fuel tank can randomly get contaminated with water. Samples from the fuel can be taken to test for contamination.
• Added GPS 196 device
• Fixed glass reflection in external views
• Improved lighting, including better looking navigation lights (and depending on viewing angle) in ALS
• Improved textures of instruments, primer, cabin air/heat levers in cockpit, and flap lever
• Smooth instead of instant animation of yoke, pedals, and parking brake
• Added menu item to open a web panel in your browser, showing most instruments
• Improved interior shadow and reflection cubes

Version 3.6

• Various ALS effects: flash light, 3D shadow, interior shadow, fog and frost, rain splashes, landing light
