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 737-800 Modification
This is a freeware Boeing 737-800 with winglets that I obtained from AVSIM. 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 CFM56-7B sounds on AVSIM.
The GPWS and Groundhandling gauges were made by Rob Barendregt. The Jelair Vspeeds/Callout gauge was made by Jacob Larsen.
**The Jelair Vspeeds/Callout gauge must be opened once to activate it.**
I have made the following modifications:
1. Removed the built-in Landing and Taxi lights from the model and added new lights in the cfg file using stock effects.
2. Modified the empty and max weight as well as the passenger and cargo loads. The loads are set up for app. 160 passengers plus luggage and other cargo. The Southwest Airlines configuration can hold 175 passengers and Ryanair can hold 189, and these can be enabled by following the instructions in the Weight and Balance section of the aircraft.cfg file.
3. Changed the moments of inertia for more realistic feel and handling.
4. Adjusted the reference datum position, station loads positions, engine positions, fuel tank positions, and contact points.
5. Corrected some airplane geometry values.
6. Set engine thrust to correct value for CFM56-7B26, added additional fuel flow gain entries for a longer and more realistic engine start sequence, adjusted fuel flow scalar for accurate fuel consumption, set engine inlet area to correct value, and changed min throttle limit for more realistic reverser thrust.
7. Modified the fuel tank values to reflect the fuel quantity for the 737-800 with standard 3 tanks. Enabled electric fuel pumps which can be turned on/off on the overhead panel.
8. Updated flap and slat values to reflect 737-800 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. You can now see the front of the wing on one side and the rear of the wing on the other.
16. Added the GPWS, Groundhandling, and Jelair Vspeed gauges to the panel.
17. Removed windshield rain effect from Boeing interior model.
18. Moved the VC forward and higher to its correct position and adjusted eyepoint view.
19. Corrected the exits section of the cfg file.
20. Adjusted the EGT max temp and scalar in the AIR file to display the CFM56-7B engine EGT more accurately.
21. Adjusted the Total Drag and landing gear drag in the AIR file for more realistic climb and cruise behavior.
22. Modified the EICAS gauge code to redline the EGT at the correct temperature.
23. 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 various levels such as fuel and EGT that trigger the master caution warning.
24. Updated the panel: replaced the radio popup panel with the stock 737-400 gauge, replaced the VC overhead panel with the Ken Wiggington panel which has indicator lights and power readings, used a different 737 gauge for the radio stack as the original radio comms didn't work, replaced the Ken Wiggington Annunciator gauge with the one from Phillippe Marion with some modifications, and replaced the TCAS gauge with a TCAS/Radar gauge which actually works.
25. Fixed the EFIS MFD map Airport and VOR layer buttons where the VOR button displayed airports and vice-versa.
26. The left end button on the EFIS opens the TCAS/Radar gauge, the second button from the right opens the Heads-up Guidance System, and the right end button opens the Overhead panel.
27. Added a mouse click area near the top of the VC console FMC that opens the 2-D FMC panel when clicked. Also fixed multiple gauge code syntax errors.
28. Fixed a hydraulic indicator light problem on the VC Overhead panel.
29. Fixed the VC Autobrake switch so it now works.
30. Modified the Jelair Vspeeds gauge to provide more accurate speeds for the 737-800.
31. Added a custom Kneeboard checklist and reference page.
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.
