I Want to Believe(in P3D)
September 2025: Another update for the 737NGs has been released. The update fixes some issues with and makes more improvements to the panel. The flight dynamics have also been tweaked again, and the kneeboard reference was updated.
The panel must now be downloaded separately and is located in Boeing 737NG Panel on the P3D Aircraft menu. I did this to save drive space. See the ReadMe for the panel as it has instructions for renaming the panel.cfg files depending on which variant the panel is for.
For the aircraft updates, just download the updated aircraft.cfg, .air file, reference document, and ReadMe and replace the old ones.
September 2025: UHWW Vladivostok Intl Airport, located in Vladivostok, Russia, is now available.
August 2025: Another minor update to the Boeing 737 NGs - fixed some panel issues, resized the 2-D popup overhead panel and Heads-up Guidance display. Just download the panel.NG folder and replace the old one.
August 2025: Additional updates were made to the Boeing 737-700, 800, and 900ER. There are some minor corrections and fixes as well as new features - fixed VC light positions, fixed checklist which didn't open due to incorrect aircraft cfg entry, corrected 737-800 VC location(moved forward a bit more), changed panel window IDs which didn't conform to the SDK and caused some odd issues, fixed EFIS MFD layer buttons where VOR button displayed airports and vice-versa, and added new VC click areas to the unused EFIS buttons to open the TCAS/Radar gauge, Heads-up Guidance System, and Overhead panel, and tweaked the Jelair Vspeeds gauge code to improve accuracy. Flight dynamics were tweaked a bit as well. You can download everything except the texture folders, or the whole aircraft if you like, and replace the old files. Please see the ReadMe for details.
August 2025: The Airbus A321 Neo LR CFM and PW models are now available. These now have the updated panels and other features/improvements like the A319-A321s, as well as updated flight dynamics. Users should download the entire aircraft and replace all the old files if you have the previous versions installed.
August 2025: The Boeing 737-700, 737-800, and 737-900ER have been updated. A number of fixes and corrections were made, some new features added, and flight dynamics were improved. There are also new kneeboard checklists and reference pages based on actual aircraft manuals and documents. Please download the entire aircraft again and replace the old files if you have the previous version installed. Please see the Readme for more details, and I recommend you read the kneeboard reference page as well.
July 2025: ZUUU Chengdu Shuangliu Intl Airport, located in Chengdu, Sichuan, China, is now available.
July 2025: The Airbus A320 CFM and PW Neos are now available. These now have the updated panels and other features/improvements like the A319-A321s, as well as updated flight dynamics. Users should download the entire aircraft and replace all the old files if you have the previous versions installed.
July 2025: I'm releasing a massive update of the Airbus A319-321s with many improvements and new features. This is the result of over 100 hours of work and testing. I restored the original Project Airbus AIR files, with some adjustments, as I discovered that they are actually more realistic. I also restored the models' attached navigation and strobe lights, now using stock P3Dv6 effects, so they flex along with the wing in flight. Users will need to download the entire aircraft and replace all the old files if you have the previous versions installed. I strongly recommend users read the ReadMe for each aircraft as well as the Kneeboard Reference page. Click for more details.
AIRBUS A319-321 MODS
This is a list of modifications, fixes, additions, and improvements that I've made to the Project Airbus A319, A320, and A321 freeware aircraft.
Several aircraft functions have been automated as in the real aircraft:
1. APU bleed will automatically open when the APU is running and both engines are off.
2. Engine Bleed will open and APU bleed will close when both engines are running.
3. Probe Heat will automatically turn on once both engines are running.
4. Hydraulic PTU will engage when only one engine is running and hydraulic pressure difference exceeds 500psi.
5. Yellow hydraulic system electric pump will automatically turn on when the APU AC power is energized and turn off when one or both engines are running and AC power generators are energized.
6. Blue hydraulic system electric pump will automatically turn on when one or both engines are running and AC power generators are energized.
The panel I started with was a modification made by Speedbird77 of the original FSX A321 panel. The original upper ECAMS gauge was made by Stefan Liebe. The Honeywell FMC was made by Garret Smith.

PANEL & GAUGES
********************************
PANEL CONFIG
1. Added Rob Barendregt's GPWS and Ground Handling gauges, Jacob Larsen's Vspeeds gauge, Garret Smith's FMC gauge, and Doug Dawson's sound gauge for the Master Warning alarm sound.
2. Removed Mini Panel, changed lower ECAMS2 popup 2-D gauge to one with working page selection buttons, reordered popup 2-D gauges.
UPPER ECAMS GAUGE
1. Added new notification messages - DOOR OPEN appears if the Cabin or Cargo door is open, APU AVAIL will appear when the APU is running, APU Bleed will appear when the APU is running and both engines are not running, IGNITION will appear when the Engine Ignition Switch is turned on, PARK BRK appears when the parking brake is engaged, HYD PTU appears when the hydraulic PTU is engaged, ENG A.ICE appears when an engine anti-ice is turned on, WING A.ICE appears when the wing anti-ice is turned on, ENG+WING A.

3. Added font color change to red if engine N1 or N2 exceed limits.
4. Adjusted engine max EGT, N1, and N2 values and flap values to match actual aircraft and engine specific values.
LOWER ECAMS GAUGE
1. Modified background image to remove bottom horizontal line, N1 label, and Fuel Used LBS label.
2. Added Fuel Used KG label, N2 labels, and new bottom horizontal and vertical lines.
3. Added Fuel Used, TAT, SAT, GMT Time, and GW readouts to the main engine page.
4. Fixed APU page bleed indicator so that it flips up when the APU is running and sideways when it is off or both engines are running.
5. Fixed Hydraulic screen Blue Electric Pump valve indicator - turns green, psi reads 3000, and ELEC appears when one or both engines are running and AC generators are energized.
6. PTU indicator appears and control line opens when the pressure difference between the engine pumps is greater than 500 psi.

8. Yellow Electric Pump (engine#2 line) automatically turns on and ELEC appears when APU AC power is energized and engines are not running.
9. Eng#1 & #2 hydraulic fire valve indicators now remain green as these only close when the Engine Fire Extinguisher is engaged which does not work on this model.
10. Fixed Bleed page APU valve indicator to flip up when the APU is running, engine valve indicators flip up when the engines are running.
11. Fixed Engine page start bleed valve indicators so that they are closed before engine starting, open when the engines are starting, and close when the N2 speed reaches 50%.
12. Fixed Fuel page Fuel Used reading which used incorrect units so reading was wrong - now correctly reads kilograms, changed FOB and fuel tank quantities to kilograms.
OVERHEAD GAUGE
1. Blue Hydraulic system electric Pump turns on automatically and button/indicator fault light disappears when one or both engines are running and AC power generators are energized.
2. When ACU AC power is energized, the Yellow Hydraulic system electric pump turns on automatically and the Eng#2 hydraulic button/indicator fault light disappears(this is actually indicated by a separate Electric Hydraulic pump button/indicator on the real aircraft and simulated here using the Eng#2 button/indicator).
3. Fixed Fuel Crossfeed button, now dark when battery on and illuminates "on" and "open" when pressed.
4. Fly By Wire Flight Control FAC 1, SEC 1, and ELAC 2 buttons toggle the Yaw Damper on or off when pressed.
