FS Crosscheck runs checklists, reads callouts, and answers back — in real time, by voice — and knows exactly what your aircraft is doing, so it never calls “gear up” before you’ve rotated.
Not a scripted soundboard. A conversational first officer that hears you, reads the aircraft, and flows through your procedures.
Natural, low-latency speech. Interrupt, repeat, or change your mind mid-callout — your FO keeps up.
Altitude, speed, gear, flaps, autopilot, phase of flight — your FO always knows the state of the aircraft, so the callouts are never wrong.
Curated flows for the airframes study-level pilots fly. A universal profile has your back in anything else.
One key opens the mic. Release to listen. Interrupt any time — you never wait for the FO to finish a sentence.
“V1”. “Rotate”. “Positive rate”. “1,000.” The right call at the right moment — every time, without you asking.
Change a checklist item or a briefing line mid-flight and the FO adapts the same second. No restart, no resetting your flight.
Designed around the reality that one of your hands is on the radio. Your FO stays quiet when you’re transmitting on a network.
A quiet desktop app that lives where your sim does. No browser, no streaming, no extra distance between you and your FO.
One subscription, one license key. No extra accounts, no third-party sign-ups, no surprises on your credit card.
Download the Windows installer. Paste your license key. That’s it — nothing else to configure.
Start any aircraft in MSFS 2020 or 2024. FS Crosscheck recognizes what you’re flying and loads the matching flow — or a universal one.
Press your PTT key. Call for a checklist, ask for altitude to level off, brief an approach. Automatic callouts handle themselves.
Scripted copilots were a miracle in 2010. In 2026 they sound like answering machines. FS Crosscheck listens, decides, and responds — like an actual right-seater in the seat next to you.
