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.
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
| 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. |
| SAPI Cabin | Selects the installed SAPI voice used for cabin announcements when SAPI speech is enabled. |
| SAPI Rate | Controls how quickly SAPI voices speak. If voices feel too slow or too rushed, adjust this before changing other audio settings. |
| Pilot Volume | Controls the loudness of pilot and copilot speech. |
| Crew Volume | Controls the loudness of flight attendant and cabin crew speech. |
| Ambiance Vol | Controls the loudness of boarding ambience, background sounds, and related non-voice cabin audio. |
| 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. |
| Amb dB Gain | Adds or subtracts decibels from ambience playback before the normal ambience volume slider is applied. |
| Readback | Controls the spacing or pacing used during readbacks, especially where letters, numbers, and short phrase groups need slightly clearer separation. |
| 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. |
| Comms Texture | Adds extra radio character such as light hiss or comms-style texture. This is mainly a realism preference. |
| Open Mic | Keeps speech recognition listening continuously unless it is muted. This is the best choice if you prefer hands-free operation. |
| 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
| 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:
|
| 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. |
| Call System Changes | Makes the copilot announce important system changes such as gear, flaps, autopilot, autothrottle, and related mode changes. |
| Reserved | Reserved for future use. |
| Call Engine Start | Enables engine-start callouts during the start sequence. |
| Call Warnings | Enables spoken warnings where supported by FSFO. |
| Auto Inflight Services | Allows cabin service to run automatically on qualifying passenger flights. |
| Press Takeoff Screw/AutoFlt | Allows FSFO to press the PMDG takeoff screw or the TFDi MD-11 Auto Flight button when the aircraft and checklist state support it. |

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. |

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:
|
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:
- Preflight
- Before Start
- Start
- After Start
- Taxi
- Before Takeoff
- After Takeoff
- Descent
- Approach
- Landing
- After Landing
- 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.
The Interface Options section of the FSFO Settings window.
