Audio & Speech

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.

Audio Devices & Voice

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.
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.
Region	Chooses the accent or regional voice style FSFO should prefer when supported by the selected voice engine.
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.
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.
SAPI Pilot	Selects the installed SAPI voice used for the captain voice when SAPI speech is enabled.
SAPI Co-pilot	Selects the installed SAPI voice used for the first officer when SAPI speech is enabled.

Voice Recognition

Setting	What it does
Recognizer	Choose which installed English Windows speech recognizer FSFO should use when Microsoft speech is selected.
General Voice	Sets the recognition confidence required for general voice commands such as checklists, flows, and non-critical speech actions. Range 0.40 to 0.90.
Checklist Voice	Sets the recognition confidence required for short checklist responses such as on, off, set, checked, and ready while FSFO is actively waiting for a checklist reply. Range 0.35 to 0.80.
Critical Voice	Sets the recognition confidence required for critical voice commands such as flaps, gear, autopilot modes, and other sensitive speech actions. Range 0.50 to 0.95
End Silence	How long FSFO waits after you stop speaking before processing the command
Train Speech	Opens the speech training window to improve recognition.
Get Help	Open documentation for configuring input and output.

Volume & Balance

Setting	What it does
Pilots Volume	Controls the loudness of pilot and copilot speech.
Crew (FA) Volume	Controls the loudness of flight attendant and cabin crew speech.
RAAS Volume	Controls the loudness of the Runway Awareness callouts
Ambiance Volume	Controls the loudness of boarding ambience, background sounds, and related non-voice cabin audio.
Boarding Music Volume	Controls the loudness of the boarding music
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.
Ambiance dB Gain	Adds or subtracts decibels from ambience playback before the normal ambience volume slider is applied.
Readback Pause	Controls the spacing or pacing used during readbacks, especially where letters, numbers, and short phrase groups need slightly clearer separation.
SAPI Rate	Controls the rate at how fast SAPI voices speak.

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.
CREW TEST	Plays a standard cabin crew announcement through the current cabin-audio output.
READBACK TEST	Plays a sample captain and first officer readback so you can judge clarity, pacing, and balance.
TEST BOARDING MUSIC	Plays the current boarding-music audio so you can confirm the selected sound and its level.
TEST BOARDING AMBIANCE	Plays the current boarding or background ambience so you can confirm the selected sound and its level.

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.
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.
GUID	Displays the unique device identifier for the selected controller. This is mainly for confirming which hardware FSFO is seeing.
INPUT	Shows the currently assigned button or key for the selected action.
SET	Starts listening for the next key press or button press so a new binding can be assigned.
CLEAR	Removes the current binding for the selected action.

Support and Maintenance Buttons

Setting	What it does
TRAIN SPEECH	Opens the Windows speech-training workflow so you can improve recognition quality.
GET HELP	Opens FSFO help or support resources from the Settings page.
CHECK FOR UPDATE	Manually checks whether a newer FSFO version is available.
DELETE	Deletes the saved controller-assignment configuration so you can rebuild bindings from scratch.

SOP

This section controls the standard operating thresholds FSFO uses during takeoff, climb, descent, approach, and landing. Most altitude values can be set to zero to disable that specific automation.

The SOP section of the FSFO Settings window.

Setting	What it does
Acceleration (AGL)	Altitude above ground where the copilot calls "Acceleration Altitude." This is often used as a visual or procedural cue during the initial climb.
Landing Lights (MSL)	Mean-sea-level altitude where FSFO manages landing lights. This lets you align light usage with your preferred transition altitude.
Engage VNAV (AGL)	Above-ground altitude where the copilot engages vertical navigation, when supported by the aircraft.
Engage LNAV (AGL)	Above-ground altitude where the copilot engages lateral navigation, when supported by the aircraft.
Engage AP (AGL)	Above-ground altitude where the copilot engages the autopilot.
Engage APPR (AGL)	Above-ground altitude where the copilot engages approach mode during landing.
Disconnect AT (AGL)	Above-ground altitude where the copilot disconnects autothrottle during landing.
Disconnect AP (AGL)	Above-ground altitude where the copilot disconnects the autopilot during landing.
Extend Gear (AGL)	Above-ground altitude where the copilot extends the landing gear during approach and landing.
Min Flap Extension (AGL)	Lowest above-ground altitude where the copilot is allowed to extend flaps. This can be used to prevent very early flap deployment.
Ground Speed Warn (MPH)	Speed threshold used for ground-speed warnings while taxiing or rolling on the ground.
Stabilized Call (N1)	N1 percentage where the copilot calls "Stabilized." This is mainly used during takeoff thrust application.
Flow Pause (sec)	Controls the delay FSFO uses between flow actions. Larger values make flows feel slower and more deliberate.
Checklist Pause (sec)	Controls the pause between checklist items or responses.
Checklist Repeat (sec)	Controls how long FSFO waits before repeating a checklist prompt when a response or matching aircraft state is still missing.
Passing Call (MSL)	Mean-sea-level altitude used for "Passing" callouts during climb or descent.
Couple Taxi Lndg Lights	Ties taxi-light behavior to landing-light behavior so they move together automatically.
Couple Wing Logo Lights	Ties wing-light behavior to logo-light behavior.
Manage Grnd Lights	Lets the copilot manage ground-light logic automatically, including combinations involving NAV, beacon, taxi, landing, strobe, and wing lights.
Eng Start	Defines how many engines must be running before FSFO considers the aircraft ready to transition from preflight toward taxi-out. On multi-engine aircraft, this can change when flows continue automatically.
Battery Equals Turn Around	If the aircraft is already powered when FSFO connects, the flight is treated more like a turnaround than a cold-and-dark startup.
Boarding Music	Selects the boarding-music file or theme used by FSFO.
Safety Message	Selects the safety-message file or theme used by FSFO.
Flaps Call	Controls how flap callouts are spoken. Depending on the selected option, FSFO can call the flap setting itself, the speed check, or both.
VSpeed Call	Controls how takeoff V-speed callouts are handled, such as none, full V1-and-Rotate behavior, or reduced callout behavior.
Note	Most threshold values in this section can be set to 0 to disable that specific automation or callout.

Crew Options

This section controls what the copilot, captain, and cabin crew are allowed to say or do automatically.

The Crew Options section of the FSFO Settings window.

Setting	What it does
Attendant Messages	Enables flight attendant cabin announcements such as boarding complete, cabin-ready reminders, descent stowage reminders, and deboarding completion.
Pilot Messages	Enables first officer or pilot-facing passenger messages such as taxi-out welcome, cruise announcements, and descent announcements.
Apply Brakes	Allows the copilot to apply braking during supported situations.
Set Landing Gear	Allows the copilot to raise and lower the landing gear automatically when required by flows or flight logic.
Set Flaps	Allows the copilot to retract and extend flaps automatically when required by flows or flight logic.
Set Altimeter	Allows the copilot to set standard or local pressure during the flight.
Set Seatbelts	Allows the copilot to manage the seatbelt sign automatically.
Set Ctr Fuel Tanks	Allows the copilot to manage center-tank fuel logic where supported.
Set Lights	Allows the copilot to manage lighting changes tied to the current phase of flight.
Repeat Readback	Makes the copilot repeat values heard in voice commands, which is helpful for catching recognition mistakes.
Confirm Checklist Item	During voice-driven checklists, the copilot checks whether the requested aircraft state is actually set and prompts again if it is not.
First Ofcr Handles Intercom	Lets the first officer handle intercom-related prompts automatically instead of requiring the captain to respond manually.
Call Missed Checklist	Warns you if FSFO believes an expected checklist was skipped.
Call Roll Phrases	Enables takeoff-roll and landing-roll phraseology such as thrust-set, speed checks, and rollout callouts.
Captain Callouts	When the copilot is flying the takeoff, this enables the captain-side callouts and responses as part of the exchange.
Call 400 Feet	Adds the 400-foot callout during climb.
Call Minimums	Enables minimums callouts on approach.
Call Glideslope Alive	Enables "glideslope alive" and "glideslope captured" callouts during approach.

Portal, Simbrief, and PAX

This section groups licensing, Pilot Portal access, user-data access, and the timing controls used for passenger-facing operations.

Setting	What it does
Open License Manager	Opens the FSFO license manager.
Pilot Portal Sign-In	Opens the Pilot Portal sign-in window.
Open User Data Folder	Opens the FSFO user-data folder in Windows.
Simbrief ID	Stores the SimBrief numeric user ID FSFO should use for dispatch and flight-plan integration.
Boarding	Controls boarding speed. Sliding to the right makes boarding slower and more extended.
Food Service	Controls inflight-service speed. Sliding to the right makes service slower and more extended.

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

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.
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.
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

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.

RAAS Options

These settings tune the Runway Awareness and Advisory System thresholds. Each threshold can be set to zero if you want that specific alert disabled.

The RAAS Options section of the FSFO Settings window.

Setting	What it does
Short Runway (FT)	Runway length, in feet, below which FSFO treats a runway as short for RAAS alerting purposes.
Approach Rwy Threshold (FT)	Distance threshold, in feet, used for the "Approaching Runway" advisory.
On Runway Threshold (FT)	Distance threshold, in feet, used to determine when the aircraft is considered on a runway.
Unstable Approach (AGL)	Above-ground altitude threshold used for unstable-approach checking.
Altimeter Warning (AGL)	Above-ground altitude where FSFO checks for an incorrect altimeter setting and can trigger an altimeter warning.
On Taxiway (IAS)	Speed threshold used for the on-taxiway advisory or warning.
Long Landing (%)	Percentage of runway used at touchdown that will trigger the long-landing advisory.
Approach Rwy Landing (AGL)	Above-ground altitude used for the landing-side "Approaching Runway" advisory.
Note	Set any individual RAAS threshold to 0 to disable that specific advisory.

Interface Options

This section controls startup behavior, convenience prompts, visual appearance, and several small interface features. Some appearance-related changes require an FSFO restart before they fully take effect.
