Description
Your Voice-Controlled Copilot for Microsoft Flight Simulator 2024
Checklist Reader adds a virtual copilot to your cockpit.
Select an aircraft, choose one of your installed Windows SAPI5 voices, and start flying.
Your copilot reads procedures, listens to your responses and monitors the aircraft through native MSFS 2024 SimConnect integration.
Everything available through the MSFS SDK / SimConnect API can be used by the system — from aircraft state and weather to flight variables and simulator events.
🛫 A Typical Flight
After takeoff you call:
After takeoff checklist.
Your copilot begins the flow.
Landing gear? — Up
Flaps? — Retracted
The checklist continues step by step — just like in a real cockpit workflow.
🧭 Situational Awareness
At any time you can ask your copilot:
• Where are we now?
• What’s next?
• What was completed last?
The system always knows your exact checklist position.
You can also query live simulator data:
• What is our altitude?
• What is our vertical speed?
• How is the weather?
• What is our current heading?
Answers come directly from live MSFS 2024 simulator data.
🧠 A Copilot That Watches the Flight
Checklist Reader does more than read checklists — it monitors your flight.
The system tracks:
• flight phase
• aircraft configuration
• altitude and speed
• simulator variables
• the active SimBrief flight plan
Your copilot can:
• announce upcoming waypoints
• track route progress
• detect abnormal flight states
• warn about configuration issues
Example alert:
Possible icing conditions detected. Consider enabling pitot heat.
📈 Flight Tracking and Debriefing
Checklist Reader records the entire flight path.
After landing you can export the track and review your flight:
• collect flights as 2D routes in Google Maps
• replay the complete flight in 3D with Google Earth
Perfect for post-flight analysis and training.
🎙 Voice System
Checklist Reader is a voice-driven terminal system with optional GUI windows for aircraft selection and simulator status.
✔ Works completely offline
✔ Supports all Windows SAPI5 voices
✔ HOTAS / Stream Deck usable via hotkeys
✔ VR friendly
🎧 Push-To-Talk Recommendation
👉 Strongly recommended: enable Push-To-Talk if your environment is not completely silent.
Background noise, keyboard clicks, ATC audio or nearby conversations can otherwise trigger unintended commands.
Push-To-Talk ensures reliable and precise voice control.
👉 Antivirus Notice ⚠
Some antivirus scanners (for example Arctic Wolf or SecureAge) may report the executable as suspicious.
These are known false positives caused by the voice recognition and simulator integration techniques used by the application.
Checklist Reader:
✔ works completely offline
✔ sends no telemetry
✔ performs no background network activity
There has never been a confirmed malware incident related to this software.

1. With recent builds, it feels like response speed has slowed down even more. If you look at this, filmed with current build, voices come more often than not with huge delay https://www.youtube.com/watch?v=5Yx18bd0Jo0 I've put timestamps into the comments. I've monitored the app's window and the command is recognized instantly, but voices are delayed to point a they hinder operating the birds. MAY6 log entries are pertinent to this vid https://pastebin.com/rgDhN655 The app went into inoperable mode on the flight and I restarted it. That is not probably in the log.
2. Executing checklist can halt in situations like this https://www.twitch.tv/videos/2754158933 Then you'll have to restart the app.
3. I´d like shortened mic toggle feedback option "on/off" That's it.
4. It is great that you've coded my progression idea. I often do multiple legs on a flight. On normal checklists, I'd be cool if sequencing would roll back altogether upon recalling checklists not in order. For example AfterLanding completed -> Before takeoff called up next -> app would suggest Climb instead of Shutdown.
5. Here are some random slow downs https://pastebin.com/Z5u5pXZR https://pastebin.com/Z4dNk2a7 and crash logs https://pastebin.com/nXt7Fj72 https://pastebin.com/7x4Y1mbV if they're useful. A bit older, though.

1. I checked the logs regarding the delayed voice responses. The recognizer itself appears to react immediately, but the spoken responses can become heavily delayed afterwards. The app has grown significantly over recent builds, so there may still be areas where additional performance optimizations are needed. I already optimized a lot internally, but I’ll continue investigating where further improvements can be made.
I also noticed repeated recognizer state warnings in the logs. Push-to-Talk should normally prevent this entirely, so I’ll investigate why the recognizer can still occasionally end up in an invalid state.
2. I also reviewed the checklist halt example. One interesting detail is that “Abort Checklist” was used at one point, which currently is not a valid command, while “Stop Checklist” for some reason was not accepted. That definitely should not happen, so I’ll investigate the command handling there as well.
3. Shorter mic toggle feedback like just “On / Off” sounds reasonable. I’ll check whether I can shorten it or make it configurable.
4. I think there may be a misunderstanding regarding the progression logic. Recalling an earlier checklist is currently treated as a repetition unless the checklist flow is actively reset using the voice command “let’s start from the scratch”. Without that reset, the system assumes you are simply repeating an earlier checklist rather than beginning a completely new cycle.
5. I also checked the slowdown/crash logs. I do not see a clear unhandled crash there, but I do see repeated recognizer state issues that match the symptoms you describe. That can explain situations where the app becomes sluggish, stops responding correctly, or requires a restart. I’ll investigate that area specifically and improve the recovery handling around recognizer re-arming and microphone state transitions.
Really appreciate the detailed testing and feedback.
Greetings
Chris

The lag is still present in checklists. However, I tried the Simconnect commands for the first time and they seemed to work quite fluidly.
The simulator status window is isn't nice to use as it appears to load something frequently and isn't responsive to inputs. I have a program which tries to place the window on certain location on my desktop setup, it may be interfering with your app, investigating.
I also got frequent "level at x" altitude messages which I couldn't get rid off. Also on short final.
App sees 300A+ loads and brings it up as an issue, while gauges show about 80A. On the Turbine Duke.
I'm using checklists from my profile by the way.
Here are 11th May logs https://pastes.io/k9pcw7Nq

You can fully control the checklist via hotkeys:
- Ctrl + Alt + C → Check current item
- Ctrl + Alt + V → Skip item
- Ctrl + Alt + B / N → Pause / Resume
- Next Checklist Anyway → jump to the next checklist section
So you can both move through individual items and switch between checklist sections without any voice interaction.
For “Next Checklist Anyway”, you just need to assign your own shortcut in the Full Configuration → Hotkeys, since it’s not bound by default.
One thing to keep in mind: the spacebar is currently used for Push-to-Talk. If you want a “press space to confirm” workflow, you’ll need to rebind that first.
In short: a fully keyboard-driven workflow is already possible 👍

But it’s actually getting simpler again with the Companion, since most things are now in one place. Not fully one-click yet (like loading a flight plan), but overall much more streamlined 👍

i dont want to use my Speakers for checklists, i want to use my Headset + MSFS Sounds via External Speakers
about 2 months ago
A setup where MSFS runs on speakers and the Checklist Reader runs on a different output device (like a headset) is unfortunately not supported right now.
However, it might still be worth checking your setup with the new diagnostic tools and logs, as they can help identify if something is misconfigured or if a virtual device (like VoiceMeeter) is interfering.

Eine Flap Overspeed-Warnung sollte nur dann erscheinen, wenn die Klappen wirklich ausgefahren sind und die Geschwindigkeit zu hoch ist. Wenn sie laut Anzeige auf 0 stehen, deutet das eher auf ein Problem hin (z. B. falsche Daten, Mapping oder ein Bug).
Ein paar Ideen zum Eingrenzen:
Tritt das auch nach dem neuesten Update noch auf?
Welche B737 genau verwendest du (z. B. PMDG, Default, etc.)?
Passiert es direkt nach dem Start oder erst im Flug?
Gerade bei der 737 könnte es auch an speziellen SimConnect-Werten oder Addon-Logik liegen – das müsste man sich genauer anschauen.
Komm am besten mal auf den Discord 👉 https://discord.gg/EchPmVtueY
Dann können wir das gemeinsam durchgehen und gezielt herausfinden, wo das Problem liegt 👍

Es warnt mich auch vor Eis, wenn trotz ich Heat aktiviert habe.

Auch bei der nativen PMDG 737 für MSFS 2024 ist es sehr wahrscheinlich, dass einige Systeme intern anders laufen und nicht sauber über die Standard-Sim-Daten ausgelesen werden können. Das würde erklären, warum du z. B. Flap Overspeed trotz Flaps 0 bekommst oder die Flap-Position gar nicht verfügbar ist.
Im nächsten Update kommt eine vollständig konfigurierbare Überwachung. Damit kannst du solche Callouts gezielt anpassen oder auch komplett deaktivieren, wenn sie mit bestimmten Flugzeugen (wie der PMDG) nicht korrekt funktionieren.
