FS1App is a modern companion application for Microsoft Flight Simulator 2020 and 2024 designed to enhance immersion, realism, and long-term progression for serious sim pilots.
The application combines advanced simulation utilities, career progression, replay technology, sound systems, real-time overlays, AI traffic engine & systems, failures, and voice interaction into a single platform built to expand the flight simulation experience far beyond the base simulator.
FEATURES
Career Mode
Experience a realistic aviation career where every decision matters. Earn licenses to unlock aircraft and operations, manage fuel, maintenance, company assignments, and base airports while progressing through a persistent economy and ranking system. Flight performance directly affects Coins, Pilot Points, Prestige, and overall progression.
FS1 Replay System
Record entire flights without compromising simulator performance, including long-haul operations. Access important moments instantly such as takeoff and landing, create custom replay points, and replay recorded live traffic captured during the flight.
Traffic & Squads
Advanced AI traffic injection engine with:
Static Traffic for parked aircraft
Active Traffic flying routes between airports
Replay Traffic generated from recorded flights
Injected traffic integrates with the simulator’s native ATC system. Includes the unique Squads formation system allowing formation flying attached to the player aircraft, replay traffic, or active AI traffic for escort flights and coordinated operations.
Traffic & Squads is built around customizable presets, allowing users to save complete traffic setups and launch them instantly with a single click. The system does not include aircraft model libraries and instead uses the aircraft already installed in the user’s simulator, providing full flexibility with existing traffic libraries and personal fleets.
Supports custom sound packs and complete category management.
FS1 CheckLister
Create fully customizable spoken checklists with text-based steps or custom WAV audio callouts. Supports keyboard, joystick, and voice command interaction to keep pilots focused on the cockpit.
FS1 Voice Commander
Control aircraft functions such as landing gear, flaps, and flight director through voice commands without removing hands from the controls.
FS1 CameraFX
Dynamic camera effects including head shake and touchdown impacts for enhanced realism during taxi, takeoff, and landing.
FLIGHT – Maps & Smart Overlays
Real-time overlays synchronized directly with the simulator displaying:
Flight performance
Live aircraft data
Timing metrics
Pilot statistics
Aircraft information
Flight cards
Flight Log
Automatically stores all completed flights both inside and outside Career Mode with detailed statistics and global map visualization of your aviation history.
Failures & Emergencies
Fully configurable emergency and failure system affecting:
Engines
Electrical systems
Brakes
Flaps
Landing gear
Pitot/static systems
Vacuum systems
Difficulty, frequency, and behavior are fully customizable.
IFR Clearances
Capture and copy IFR clearances directly from ATC including departure, taxi, and arrival instructions for faster and more organized operations.
Flight Data Requests
Request real-time aircraft and environmental data via voice commands with audible and text responses including:
Speed
Fuel
Remaining flight time
Estimated arrival
Wind
Altimeter
Temperature
Aircraft autonomy
FS1App is built for sim pilots seeking a deeper, more immersive, and more realistic flight simulation experience.
