The TFDi Design MD-11 is an ultra high fidelity simulation of the iconic McDonnell Douglas three-engine transcontinental airliner for Microsoft Flight Simulator 2020 and 2024.
Comprehensive Systems Simulation
Based on both real-world manuals and pilot and mechanic experience.
Onboard Systems
Each onboard system has a detailed simulation of both its physical behavior and the automatic control computer that manages it. The electrical system dynamically propagates load, the hydraulic system realistically pressurizes over time with varied per-system values, the air system responds to bleed configurations and environmental conditions, and the fuel system manages complex transfer and temperature control behavior.
Flight Controls
Advanced and unique features like the dial-a-flap system, control surface droop, and deflected aileron package are fully simulated.
Persistence
Continue where you left off with full system state persistence.
Advanced Flight Management System & Autopilot
Experience professional-grade flight planning and management via SIDs and STARs, realistic time and fuel predictions, performance/cost index management, custom waypoints, wind data entry, and holding pattern capabilities. Full simulation of the autoflight and autothrottle system from TAKEOFF pitch guidance to dual AUTOLAND can guide you runway to runway.
ACARS/CPDLC Simulation
Communicate with air traffic control using the MCDU.
LSAS & RCWS
Fully implemented Lateral Stability Augmentation System (LSAS) and optional Roll Control Wheel Steering for enhanced manual flight assistance.
Dynamic Display Systems
Experience the 6 rounded digital displays of the MD-11 cockpit, offering visibility into all critical flight and systems data.
CRT Technology
- Authentic warm-up sequences
- Display computer simulation
- Screen shuffling behavior
Alert and Data Systems
- Realistic engine display data and animation
- Full master caution/warning and hundreds of possible alerts
- Full system synoptics
Display Options
- Tape or dial style engine displays
- Flight director type and rising runway behavior
- Analog or digital standby
- Wind display types
Multiple Engine Variants
Recreate your preferred operator with your choice of the CF6-80C2 or PW4460/4462 engines, each with their own unique performance and sound profiles. Both variants are driven by a custom full authority digital engine controller (FADEC).
General Electric CF6-80C2
- Realistic N1 control
- Iconic whine sound
- Lower pressure oil system
- Realistic earlier engine data display
Pratt & Whitney PW4460/62
- Custom EPR simulation
- Livery-selectable 4460 or 4462 variants
- Higher pressure oil system
- Realistic delayed data during startup

PACX
PACX seeks to bring the feeling of responsibility and the significance of traveling with passengers and crew to your simulator.
Announcements
Over 800 different sounds make every flight sound different. You will hear your actual destination, flight number, time of day, outside temperature, and flight-specific announcements like cabin lights dimming or customs.

Announcements
Over 800 different sounds make every flight sound different. You will hear your actual destination, flight number, time of day, outside temperature, and flight-specific announcements like cabin lights dimming or customs.
Passenger Simulation
Passengers will react to, and judge, events throughout your flight. A business traveler may be more affected by delays than a passenger going on vacation. Customizable career options can further affect the passenger feedback.
Keeping Everyone Informed
Interact with your passengers and crew in a realistic, easy way.
Direct Interaction
Using the announcement menu or the in-sim HUD, you can inform passengers of delays, diversions, aircraft problems, and more. You can also answer crew questions or request an update on their status. On certain aircraft, interaction can be initiated by pressing the appropriate in-cockpit controls on select third party aircraft.
Vocal Interaction
Vocal recognition technology allows you to make realistic public addresses. Use this system to interact with your passengers and crew in a realistic way. If desired, you can hear your announcement played back like as if through a PA speaker.
Progressing through Flights
In-flight incidents and a powerful, intuitive records system help make every flight count.
Incidents
You may encounter dynamic and random medical incidents, reseating requests, and baggage issues. Some incidents just cause a slight delay, some require much more.
Records
The records system automatically backs up your flights and lets you view your history. You can track your progression through your career with career mode, view statistics, and earn awards for flying performance.
More Information
In addition to these features, PACX offers integration with other software like SimBrief and smartCARS. As well, live streamers and developers can integrate PACX using our utilities and development kit.
