Standard Operating Procedures (SOP)
NOTE: Above Ground Level (AGL) vs Mean Sea Level (MSL)
- AGL (Above Ground Level) is your aircraft’s height above the terrain directly below you.
- MSL (Mean Sea Level) is your altitude above average sea level.
FSFO will trigger the actions listed below when the aircraft reaches the specified AGL or MSL value. Setting a value to 0 disables that trigger.
OPTIONS:
- Acceleration Altitude (AGL)
Copilot calls “Acceleration Altitude” once this altitude is reached after takeoff.
- Landing Lights (MSL)
Copilot toggles landing lights at this altitude.
- Engage VNAV (AGL)
Copilot engages vertical navigation mode.
- Engage LNAV (AGL)
Copilot engages lateral navigation mode.
- Engage AP (AGL)
Copilot engages the autopilot.
- Engage APPR (AGL)
Copilot engages approach mode during landing.
- Disconnect AT (AGL)
Copilot disconnects autothrottle during landing.
- Disconnect AP (AGL)

- Min Flap Extension (AGL)
Minimum altitude at which copilot deploys flaps.
- Grnd Speed Warn (MPH)
Warns when ground speed exceeds this value.
- Stabilized Call (N1)
Copilot calls “Stabilized” when engines reach this N1%.
- Passing Call (MSL)
Copilot calls “Passing X feet” during climb or descent.

USER
Selecting the user setting allows you to choose any event/time/Lights/System/Etc to trigger your flow
- Manage Ground Lights
Copilot will manage the lights when the aircraft is on the ground:
- When Power is established, the copilot turns on the NAV Lights
- When engines are running, the copilot turns on the Beacon Lights
- When the aircraft ground speed exceeds 5 MPH, the copilot will turn on Taxi Lights
- When the aircraft is on any runway, the copilot will turn on the Landing, Strobe and Wing Lights; when the aircraft exits the runway, he will turn them off.
- Battery Equal Turn Around
IF the power is on when FSFO is connected, the copilot will consider the current flight as a subsequent flight.
- Boarding Music
Select the boarding music, which can be played via “Boarding_Music” command via the flow and checklist editor, or by click ing the music icon via the control options, which can be accessed on the Checklist page. You can also download and play your own boarding music, as long as its a.wav file. Place your wav files in the following directory: C:\Users\[USER NAME] \AppData\Local\FSFO_V6\ Music..
- Safety Message
Select the safety message, which can be played via “Safety_Message” command via the flow and checklist editor, or by clicking the life jacket icon, which can be accessed on the SOPs page. You can also download and play your own safety messages, as long as it's a *.wav file. Place your wav files in the following directory: C:\Users\ [USER NAME]\AppData\Local\FSFO_V6 \Safety.
- Flaps Call
Controls flap callout behavior:

- Confirm Checklist Item
Copilot will ensure the system is set correctly during the checklist phase, when using the voice options. If it's not set according to the checklist, your copilot will ask you to check the system again.
- First Officer Handles Intercom
Copilot will automatically handle all intercom messages and prompts (e.g., cabin/ground/crew calls) without requiring your input. If disabled, the captain (you) must answer the intercom phone and respond to prompts by selecting Yes or No in the on-screen dialogue window.
- Call Missed Checklist
Copilot will alert you when you missed a checklist. For example, if the engines are running, and you failed to complete the Before Start Flow/Checklist, your copilot will ask: “Did we complete the Before Start Checklist”?
- Call Roll Phrases
Copilot will execute takeoff and landing roll callouts (e.g. stabilized, thrust set, 80 knots, reverse green, manual braking, etc…).
- Call Roll Responses
Pilot will respond to the copilot takeoff/rollout calls. For example, when the copilot states 80/100 knots, the pilot will respond “checked.” Disable if you prefer to respond yourself.
- Call 400 Feet
Copilot will call 400 feet when the aircraft reaches this Above Ground Altitude (AGL) during the climb phase. This is useful for engaging the appropriate vertical navigation mode.

Copilot will alert the pilot when combustion is detected for each engine (e.g. engine one started), as well as call “engines stable” when all engines have stabilized.
- Call Warnings
Copilot will alert the pilot when a particular system is not correctly set. For example, he will call “check the flaps” when the aircraft is on the takeoff runway with flaps zero, or “check the door” when the door is open and the engines are running.
- Auto Inflight Services
Flight attendants will automatically run in-flight beverage/snack service. Service begins only after Top of Climb (TOC), on flights over 250 NM, and only on passenger flights (no cargo). If any of these conditions aren’t met, service will not start.
- Press PMDG Takeoff Screw
Copilot presses the TOGA Screw when the aircraft's N1 is > 60% and the Before Takeoff Checklist has been completed
General Options
- Disable Gear or Flaps Control
Copilot will ignore any flap or gear speech recognition request. For example, if you say "gear up", your copilot will ignore this command.
- Disable Radio Commands
Copilot will ignore any radio and transponder commands. For example, if you say "set comm one, 22800", your copilot will ignore the command.
- Disable Flap Calls
Copilot ignores manual flap adjustments and wont make callouts. Example: if you change flaps from 2 to 1, the copilot will NOT announce “Flaps 1."
- GSX Interface
FSFO will request GSX vice MSFS services when clicking on the appropriate button via the Checklist Page (Control Group Box). For example, if you click on the catering button, and this option is enabled, FSFO will use the GSX menu to request catering services.
- Say Intentions Interface
Pauses FSFO during ATC conversations.
- Sync Vspeed
FSFO will try to read V1, VR, and V2 from the aircraft’s LVARs shortly after engine start, and will read VREF shortly after Top of Descent (TOD). When available, these aircraft-provided values override (replace) any speeds entered on the FSFO Performance page.
- Use FMC Vspeeds
Copilot will use your FMC internal v-speed database instead of inserting the values downloaded from Simbrief. For example, on the PMDG 737, the copilot will hit the corresponding line key to load the appropriate v-speed from the FMC database. Note this only works for some aircraft (e.g. All PMDG, FBW A320, etc…).
- Play Ding Before Message
Plays a ding before cabin announcements.
- Boarding or Cargo Sounds
Plays boarding or cargo ambiance.
- Verbose Mode
Copilot will announce his flow actions. Typically, flows are conducted silently, while checklist requires a verbal call and response. However, if you want to hear what actions your copilot is taking during the flow phase, you can enable this option.
