X Plane 12 Copilot Take OFF Climb LUA Script.
This X Plane 12 Copilot Take OFF Climb LUA Script can be used alongside the Baron58_Copilot_Startup Lua Script as the Copilot start up takes you from ENGINES RUNNING at the FBO/HANGER to the runway ready to take off into the blue sky beyond!
The X Plane 12 Copilot Take OFF Climb LUA Script follows on with Rotate call at 85 knots, Gear up and Flaps up at 120 knots plus a climb recommendation on Speeds as an initial best rate climb of 105 Knots then shortly after a 125 cruise climb recommendation.
Initially the X Plane 12 Copilot Lua Script script is dormant until you exceed 30 knots! If your at a windy location and the wind is howling then it may trigger the script but not until you reach 85 knots will it say anything regardless.
SAFETY CALLOUT – You Don’t Want To Hear It!
The safety callout does not always sound and if you never hear it your doing well! The POWER,POWER,POWER callout is only triggered if you pass 110 knots and for some unknown reason or distraction drop back to 100 knots or less!
In the real world many pilots die by getting distracted on takeoff then often climb to steeply causing a stall and often a deadly spin into the ground from around the 500ft mark. This small section is designed to get your attention if that occurs and hopefully save your Virtual Pilots Life!
What Does This Script Say?
- Eighty Five Knots, Rotate – Call at 85 Knots
- Gear Up – Flaps Up – Call at 120 Knots
- Initial Best Climb Speed Reminder – 105 Knots
- Best Cruise Climb Speed – 125 Knots
- EMERGENCY – POWER POWER POWER – If your going to stall after passing 120 knots.
———————————–
Can I Edit the Script?
Yes, absolutely your very welcome to edit the spoken words which are highlighted below for you. This is one of the line so you can identify what’s changeable –
speakNoText(“Positive rate, gear up“)
You can change the format or wording and even add your name if you want where it says SIR! On my own sim it calls me by name which is a nice touch.
Commas put a small pause between words but the Brackets ( ) and the Inverted Commas “” must stay as you see them.
What Not To Do!
I don’t recommend you adjust anything other than the X Plane 12 Copilot Lua Script other than the highlighted spoken areas. I have spent a week on this little script and I can tell you unintended consequences come from adjusting the figures if your not absolutely sure what they do!
Please keep copies of the files you download in a separate area, especially if your playing and editing them so you have a place to go back to if it goes wrong.
Create Your Own File.
Copy everything BETWEEN the Dotted LINES and Paste into a NOTEPAD page!
Name it TakeOff_Climb.lua
ENSURE you change the file type from TXT to ALL FILES.
If you look at your file and it says TakeOff_Climb.lua.txt you didn’t do correctly ok! Resave it and change the FILE TYPE in the lower save box to ALL FILES and you will see it named correctly as TakeOff_Climb.lua – OK
Please the file in your X Plane 12/resources/plugins/flywithlua/scripts folder.
Your ready to GO!
Further Tested and updated 25/6/2025.

X Plane 12 Copilot Lua Script – Common Issues & Troubleshooting
While the TakeOff_Climb.lua Script has been extensively tested by Brendon McAliece (AKA Gunnie) of LETSFLYVFR.com, there may still be occasional issues, especially as the script is still in beta. The script included I flew with today and works perfectly!
Common Issues:
- No Speech or Callouts: Ensure FlyWithLua NG is properly installed. If the Lua script isn’t executing, it might be due to missing files or incorrect setup. Check the installation steps carefully.
- Script Not Running: Double-check that the script file is saved with the correct .lua extension and placed in the FlyWithLua/Scripts/ folder.
- Missing Datarefs or Errors in Log: If you see errors about missing datarefs, it may indicate that a specific part of the aircraft model or X-Plane setup is not fully compatible with the script. Report any issues in the comments or contact us.
- Performance Issues: If the script causes performance issues, try disabling other scripts temporarily to identify potential conflicts.
