FSFO Settings Reference

A practical guide to every setting in the FSFO Settings window, organized in the same top-to-bottom order as the live WPF interface.

Flight Simulator First Officer • Settings • Audio • SOP • Crew • RAAS • Interface

This page documents the current FSFO Settings window in the same top-to-bottom order that the sections appear in the WPF interface. The Settings window is organized by sections rather than old wiki categories, so this page follows the live app layout.

Input and Output
Audio, speech, controls

SOP
Automation thresholds

Crew Options
Copilot and cabin behavior

General Options
Integrations and quality-of-life

Portal, Simbrief, and PAX
Portal, SimBrief, passengers

Flow Options

Tip: Most numeric automation thresholds can be set to 0 to disable that specific callout or automation. Start with defaults, then adjust only the sections that affect your aircraft or operating style.

Input and Output

This section controls audio devices, speech recognition, SAPI voice selection, testing tools, and controller or hot-key assignments.

The Input and Output section of the FSFO Settings window.

Voice, Audio, and Recognition

Voice, Audio, and Recognition

Setting	What it does
Pilots	Selects the playback device used for captain and first officer voices. Use this if you want pilot voices in a headset while keeping other sounds on speakers.

Setting	What it does
Cabin Crew	Selects the playback device used for cabin crew announcements. Many users keep this on speakers to make the cabin sound more separate from cockpit audio.

Setting	What it does
Region	Chooses the accent or regional voice style FSFO should prefer when supported by the selected voice engine.

Setting	What it does
Speech Eng	Selects the speech engine FSFO will use. Microsoft Speech is usually the most accurate. VOSK is useful for offline or alternate-device support. SAPI mode is used when you want to choose installed SAPI voices directly.

Setting	What it does
Mic Input	Selects the microphone or input device FSFO should listen to when the chosen speech engine supports direct device selection. Microsoft Speech generally uses the Windows default microphone, while VOSK can use the device selected here.

Setting	What it does
SAPI Pilot	Selects the installed SAPI voice used for the captain voice when SAPI speech is enabled.

Setting	What it does
SAPI Co-pilot	Selects the installed SAPI voice used for the first officer when SAPI speech is enabled.

Setting	What it does
SAPI Cabin	Selects the installed SAPI voice used for cabin announcements when SAPI speech is enabled.

Setting	What it does
SAPI Rate	Controls how quickly SAPI voices speak. If voices feel too slow or too rushed, adjust this before changing other audio settings.

Setting	What it does
Pilot Volume	Controls the loudness of pilot and copilot speech.

Setting	What it does
Crew Volume	Controls the loudness of flight attendant and cabin crew speech.

Setting	What it does
Ambiance Vol	Controls the loudness of boarding ambience, background sounds, and related non-voice cabin audio.

Setting	What it does
Pilots dB Gain	Adds or subtracts decibels from pilot voice playback before the normal volume slider is applied. This is useful when a voice is technically too quiet even with the slider raised.

Setting	What it does
Amb dB Gain	Adds or subtracts decibels from ambience playback before the normal ambience volume slider is applied.

Setting	What it does
Readback	Controls the spacing or pacing used during readbacks, especially where letters, numbers, and short phrase groups need slightly clearer separation.

Setting	What it does
Headset Tone	Applies headset or intercom-style coloration to voice playback so the audio sounds more like cockpit comms and less like plain desktop speech.

Setting	What it does
Comms Texture	Adds extra radio character such as light hiss or comms-style texture. This is mainly a realism preference.

Setting	What it does
Open Mic	Keeps speech recognition listening continuously unless it is muted. This is the best choice if you prefer hands-free operation.

Setting	What it does
Start Speech On Start	Automatically turns speech recognition on when FSFO starts, so you do not need to enable it manually every session.

Audio and Speech Test Buttons

Audio and Speech Test Buttons

Setting	What it does
PILOT TEST	Plays a sample captain, first officer, and ground-audio test through the currently selected output so you can confirm routing and levels.

Setting	What it does
CREW TEST	Plays a standard cabin crew announcement through the current cabin-audio output.

Setting	What it does

Controller and Hot-Key Setup

Controller and Hot-Key Setup

Use this area to assign a joystick button, yoke button, or keyboard key to a specific FSFO action.

Setting	What it does
Controller	Selects the controller or input device FSFO should read from while you are assigning or reviewing bindings.

Setting	What it does
Action	Selects which FSFO function you are binding. Current actions include:

• PTT - Push-to-talk. If Open Mic is off, this temporarily opens speech recognition while held. If Open Mic is on, it works more like a hold-to-mute input.
• MUTE - Toggles speech recognition on or off.
• BYPASS - Skips a wait state or bypasses the next required checklist or flow hold.
• PAUSE - Pauses FSFO actions until toggled again.
• MIN - Minimizes or restores the FSFO main window.
• ACTION - Starts the currently available checklist or flow action.
• COPILOT PLANE - Triggers the "Your Plane" request so the copilot can take control when supported.
• PUSHBACK LEFT - Requests pushback with the nose turning left.
• PUSHBACK RIGHT - Requests pushback with the nose turning right.
• PUSHBACK STRAIGHT - Requests straight pushback.
• PUSHBACK STOP - Stops the current pushback.
• PUSHBACK ABORT - Cancels the pushback entirely.

Setting	What it does
GUID	Displays the unique device identifier for the selected controller. This is mainly for confirming which hardware FSFO is seeing.

Setting	What it does
INPUT	Shows the currently assigned button or key for the selected action.

Setting	What it does
SET	Starts listening for the next key press or button press so a new binding can be assigned.

Flow Options

This section controls how FSFO starts flows automatically. If you leave Auto Flow Policy on one of the built-in modes, FSFO uses its internal logic. If you switch to USER, you can define your own event logic phase by phase.

The Flow Options section of the FSFO Settings window.

Setting	What it does
Auto Flow Policy	Selects the overall automation style:

• SMART - Uses FSFO's more complete automatic logic based on aircraft state, phase of flight, runway proximity, doors, brakes, and altitude.
• LIGHTS - Uses aircraft lighting and related state cues as the primary automation trigger.
• USER - Lets you define your own trigger logic for each flow phase.
• NONE - Turns off automatic flow starts so you can trigger items manually.

Custom USER Flow Phases

Custom USER Flow Phases

When Auto Flow Policy is set to USER, each phase row has three controls:

Setting	What it does
Event	The type of condition FSFO should watch for. Available event types include OFF, NONE, TIME, IAS, AGL, MSL, TOD, SYSTEM, LIGHTS, and EVENT.

Setting	What it does
Trigger	The sub-condition FSFO should watch within that event type. Available triggers include NA, BRAKE, DOORS, FLAPS, LANDING, BEACON, TAXI, NAV, RUNWAY, and PUSHBACK.

Setting	What it does
Value	The comparison value used by the event. For numeric event types this is usually a number. For SYSTEM, LIGHTS, or EVENT-based rows this is usually a logical state such as TRUE or FALSE.

FSFO currently exposes custom rows for these phases, in this exact order:

1. Preflight
2. Before Start
3. Start
4. After Start
5. Taxi
6. Before Takeoff
7. After Takeoff
8. Descent
9. Approach
10. Landing
11. After Landing
12. Shutdown

Setting	What it does
Tip	Set Event to OFF or NONE to disable a row. SYSTEM, LIGHTS, and EVENT use Trigger plus TRUE/FALSE style values. TIME, IAS, AGL, MSL, and TOD use numeric values. TOD is entered in nautical miles.
