Learn how FS2Crew's virtual co-pilot, voice and button controls work, which aircraft need dedicated profiles, and how to fix common problems.
FS2Crew is a family of third-party crew-simulation add-ons for compatible flight-simulator aircraft. It turns normal airline procedures into a two-person workflow: you act as captain, while a simulated first officer responds to voice or button commands, reads checklists, makes call-outs and operates assigned cockpit systems.
Across supported Microsoft Flight Simulator, FSX and Prepar3D products, FS2Crew reads aircraft states and sends commands through aircraft-specific interfaces. It is not one universal virtual co-pilot: each package supports particular aircraft, simulator versions and control methods.
How does FS2Crew work during a flight?
FS2Crew runs a scripted set of crew procedures tied to flight phases, cockpit states and commands from the user.
- Load a supported aircraft: The FS2Crew product must match the exact simulator and aircraft add-on. A package designed for one developer's 737 or 747 cannot be assumed to work with another version of that aircraft.
- Start from the expected panel state: The crew programme needs to know whether the aircraft is cold and dark, powered at the gate or ready for departure. Starting halfway through a procedure can leave required triggers unsatisfied.
- Select voice or button control: In voice mode, recognised phrases initiate checklists and crew actions. Button-control editions use an on-screen interface, assigned key or controller input instead.
- Follow the included procedure: Commands such as starting a checklist or asking for a crew flow move the programme through pre-flight, engine start, taxi, take-off, climb, approach and shutdown.
- Monitor the result: The virtual first officer operates only the controls assigned by that package. The captain must still verify switch positions, indications and checklist responses.
Some editions also add cabin announcements, ground-crew conversations or pushback coordination. Those features vary by aircraft package and should not be assumed from the FS2Crew name alone.
What is the difference between a flow and a checklist?
A flow is a sequence of cockpit actions performed by a crew member; a checklist verifies that critical items are in the correct state. A common mistake is to expect every checklist challenge to operate the relevant switch automatically.
Where the aircraft integration exposes a system's state, FS2Crew may check the actual control before giving a response. A missed flow, open door, incorrect light position or unarmed system can therefore stop or alter the checklist rather than producing the expected reply.
For a concrete older FSX example, our step-by-step PMDG 747-X crew tutorial demonstrates an end-to-end flight. The condensed 747-X call-out and checklist reference shows the same concept in a shorter format. Interfaces differ in newer products, but the flow-and-checklist principle remains useful.
Does FS2Crew fly the aircraft for you?
FS2Crew does not replace the pilot, flight-management system or autopilot. It automates selected duties that would normally belong to another crew member, while you remain responsible for flying, programming the route and managing the operation.
The exact division of duties is aircraft-specific. One package may let the first officer set lights, radios and engine controls; another may assign fewer systems. Do not assume it will communicate with online ATC, enter an entire route or recover an unstable approach unless the product documentation explicitly assigns that task.
Aircraft automation remains separate. Our explanation of how flight-simulator autopilots control the aircraft covers the systems that actually hold headings, altitudes and flight-path modes.
Should you use voice control or button control?
Choose voice control for natural captain-and-first-officer interaction; choose button control when microphone use or speech recognition would be inconvenient.
| Control method | Best suited to | Main drawbacks |
|---|---|---|
| Voice control | Hands-on flying, headset users and realistic checklist exchanges | Requires supported speech components, correct microphone selection and the expected phraseology |
| Button control | Shared rooms, unreliable speech recognition and users who prefer predictable inputs | Less natural and may require extra key or controller assignments |
Availability depends on the individual FS2Crew product. Check that the edition provides the control method you want rather than assuming every aircraft package includes both.
Why is FS2Crew not responding?
Most FS2Crew failures come from a compatibility mismatch, an incomplete procedural trigger or an input problem rather than a broken aircraft installation.
- Confirm exact compatibility: Match the simulator, aircraft developer, aircraft variant and FS2Crew edition. Similar aircraft names do not make packages interchangeable.
- Check the starting state: Load the panel state expected by the procedure and complete prerequisite actions such as powering the aircraft or initiating the relevant crew flow.
- Follow the sequence: If the first officer appears stuck, review the previous checklist or flight-phase trigger. Skipping straight from boarding to engine start often leaves the programme waiting for an earlier event.
- Use the documented phrase: Voice recognition may understand ordinary speech but still reject wording outside the package's command grammar.
- Verify the audio chain: Select the intended microphone, check the operating system's speech language where applicable, and remove conflicting push-to-talk assignments.
- Inspect input conflicts: Duplicate keyboard or controller bindings can send an FS2Crew command and an aircraft command at the same time.
Aircraft and simulator updates can also affect integrations. When a problem begins after an update, confirm that the installed FS2Crew build supports the revised aircraft before resetting profiles or reinstalling everything.
Who is FS2Crew best for?
FS2Crew is most useful for solo pilots flying a supported complex airliner who want realistic crew workload, call-outs and standard operating procedures. It is less suitable if you want a general-purpose AI pilot, use an unsupported aircraft, or prefer to operate with heavily customised procedures that conflict with the package's scripted sequence.
