Flight dynamics have been modified based on official Boeing technical specifications and hours of testing. Many updates and improvements. Original aircraft made by Project Opensky. Please see the Readme file.
Boeing 767-400ER Modification
This is a freeware Boeing 767-400ER that I obtained from Simviation. The original model was developed by Project Opensky. The VC was updated by Alejandro Rojas Lucena with additional panel updates by Phillipe Marion and Ken Wiggington. The built-in FMC is from Garret Smith.
Aircraft engine sounds are not included. There are good freeware GE CF6-80 sounds on AVSIM.
The GPWS and Groundhandling gauges were made by Rob Barendregt. The Jelair Vspeeds gauge was made by Jacob Larsen.
***Be aware that the 767 engine N1 and N2 readings can and do exceed 100% during takeoff and climb. Their limits are 117.5% and 112.5% respectively.***
I have made the following modifications:
1. Removed the built-in landing lights from the model and added new landing and taxi lights in the cfg file using stock effects. I was not able to remove the built-in navigation, beacon, and strobe lights, but they work quite well. The only issue is that the navigation lights switch in the panel will also turn on the beacon and strobe lights.
2. Modified the empty and max weight as well as the passenger and cargo loads. The loads are set up for app. 243 passengers plus luggage and other cargo.
3. Changed the moments of inertia for more realistic feel and handling.
4. Adjusted the reference datum position, engine positions, fuel tank positions, and contact points.
5. Corrected airplane geometry values.
6. Set engine thrust to correct value for the GE CF6-80C2B8F, added additional fuel flow gain entries for a longer and more realistic engine start sequence, changed min throttle limit for more realistic reverser thrust, and adjusted engine fuel flow for accurate fuel consumption.
7. Modified the fuel tank values to reflect the fuel quantity for the 767-400ER. Enabled electric fuel pumps which can be turned on/off on the overhead panel.
8. Updated flap and slat values to reflect 767-400ER actual settings and adjusted scalars for realistic performance.
9. Adjusted some flight tuning scalar values for more realistic handling.
10. Changed toe brake scale for more realistic braking effect.
11. Adjusted some autopilot values.
12. Enabled electric hydraulic pump and enabled wing deicing.
13. Enabled the gear warning system and adjusted settings.
14. Removed the wing folding, tailhook, and smokesystem sections. Added the contrail effect to the effects section.
15. Added some VC views and adjusted some view positions and zoom levels.
16. Added the GPWS, Groundhandling, and Jelair Vspeed gauges to the panel.
17. Moved the VC forward to its correct position and adjusted eyepoint view.
18. Corrected exits section in the cfg file.
19. Adjusted the EGT max temp and scalar in the AIR file to display the CF6-80C engine EGT more accurately.
20. Adjusted the Total Drag and landing gear drag in the AIR file for more realistic climb and cruise behavior.
21. Modified the EICAS gauge code to redline the EGT at the correct temperature and to redline engine N1 and N2 at the correct RPM.
22. Modified the Annunciator Master gauge code to only activate the Icing warning if the temperature is below 5C *and* it is raining, snowing, or the plane is in clouds, and adjusted the EGT temperature level that triggers the master caution light.
23. Updated panel to replace the radio popup panel to the stock 737-400 gauge and replaced the VC overhead panel with the Ken Wiggington panel which has indicator lights and power readings.
24. Modified the panel.cfg to use a different 737 gauge for the radio stack as the original radio comms didn't work.
25. Replaced the VC gray-colored textures with brown-colored textures as in the real 767 and upscaled the texture size for better detail.
The modifications were made based on official aircraft specifications contained in Boeing documents. The aircraft was tested using P3Dv6, but should work fine in P3Dv4-6 and possibly even earlier versions and FSX.
