The MVP-XP50T Sim is a highly detailed avionics simulation built to enhance the King Air C90B cockpit in X-Plane 12 with unmatched realism and precision. Developed entirely in C++ and integrated natively with the X-Plane SDK 4.1.1, it includes two independent engine plugins and a dedicated subpanel for alarm and timer control, ensuring seamless synchronization with aircraft systems.
Windows Only at this time. Mac Installer will come soon
1. Main Engine Screen
This screen displays all primary engine data essential for turbine operations:
- Torque (arc gauge with color-coded ranges)
- ITT (Inter-Turbine Temperature)
- Ng (Gas Generator Speed)
- Np (Propeller RPM)
- Oil Pressure and Oil Temperature (strip gauges)
- Fuel Flow and Fuel Pressure (strip gauges)
- Crew Alerting System (CAS) annunciators, up to 24 alerts
- Outside Air Temperature (OAT)
- Electrical voltage and amperage
- Integrated flight clocks
- Anti-Ice visual alert when OAT < -3°C
- Intake Ice annunciator confirming switch activation
- Supplemental annunciators for
- Pitot Heat
- Anti-Ice
- Intake Ice (engine-specific annunciation)
2. System Screen
This screen provides animated monitoring of secondary aircraft systems:
- Aileron Trim indicator (animated)
- Elevator Trim indicator (animated)
- Rudder Trim indicator (animated)
- Flap position display with progressive animation
- “UNSAFE” flap alert during transition
- Landing gear position with UP, DOWN, and Transit animation
- Automatic gear warning logic tied to speed and power
3. Fuel Management Screen
This is the core planning and endurance page, combining fuel and navigation data:
The MVP-XP50T features built-in Haversine calculation, enabling precise determination of the distance between two geographic points on the Earth’s surface, accounting for its curvature. This functionality is seamlessly integrated with its navigation and fuel calculation tools, enhancing the instrument’s realism and operational utility within the simulator.
- Fuel levels per tank (Left, Right, Aux L, Aux R)
- Total fuel quantity (color-coded)
- Fuel Flow Total (real-time burn rate)
- Used Trip (fuel since engine start)
- Used Since Fill (fuel since last refuel)
- Fuel Remaining (usable)
- Time-to-Empty (T to E)
- Distance-to-Empty (D to E)
- GPS data:
- Active waypoint name
- Track to waypoint
- Groundspeed (knots)
- Efficiency (NM per gallon or MPL)
- Altitude
- Predictions to waypoint:
- Fuel to waypoint
- Time to waypoint
