What's inside Rafale

  1. Overview of the IPS Standby Flight Display

    The IPS (Integrated Primary System) serves as the aircraft's standby flight display, providing essential flight parameters if the main displays fail. It is located on the main panel and is powered by an independent electrical circuit. Brightness is controlled via the IPS Brightness Knob.

  2. Overview of the Rafale electrical system

    The Rafale electrical network consists of multiple AC and DC buses designed for redundancy and fault tolerance. Under normal operating conditions, the system is managed automatically via the 5K selector, requiring no pilot action. System status can be monitored on the LD MISC page.

  3. Overview of the PDS2 auxiliary display

    The PDS2 is an auxiliary display located on the main panel that summarizes active autopilot modes and IFF (Identification Friend or Foe) settings. Its brightness is controlled via the PDS2 Brightness Knob.

  4. Overview of the Center Display (HCD)

    The center display (HCD) is located below the HUD and serves as a tactical map for navigation and situational awareness. It displays the aircraft's ground speed, selected map range (in nautical miles), and current safety height in the upper-right corner. Brightness is controlled via the HCD Brightness Knob.

  5. Overview of the PDS1 auxiliary display

    The PDS1 is an auxiliary display located on the main panel used to select the primary mode and the page displayed on the Lateral Display (LLD). Its brightness is controlled via the PDS1 Brightness Knob. The display features two pages of buttons; use the arrow button in the lower-right corner to toggle between them.

  6. Overview of Jaguar flight control surfaces

    The Jaguar aircraft utilizes a specific configuration of control surfaces: two independent horizontal stabilizers (which function as both elevators for simultaneous movement and aileron-like surfaces for differential movement), two spoilers located ahead of the wing trailing edge, and one vertical stabilizer. Control is managed via hydraulic servo-actuators with redundancy provided by two independent hydraulic circuits.

  7. Overview of the Horizontal Situation Indicator (HSI)

    The Horizontal Situation Indicator (HSI) is the aircraft's primary navigation display. It can be accessed via the RLD Page Selection Switch or assigned to a lateral display from the LD DAS page.

    Key display elements include:

    • Compass Rose: Indicates aircraft heading (True or Magnetic). Reference markers appear every 45 degrees.
    • Center of Rose: Displays calculated wind direction and speed in knots.
    • Lower Section: Displays ground speed and fuel consumption per nautical mile (kg/nm).
    • Layout: Divided vertically into two sections: the left for the Primary Goal and the right for the Secondary Goal.

  8. Understand the OV-10 Bronco Garrett T-76 engine architecture

    The OV-10 Bronco uses Garrett T-76 fixed-shaft turboprop engines (715 shp). Unlike free-turbine engines (like the PT6), the turbine and propeller are directly connected to a common shaft. This means engine speed changes directly affect propeller speed.

    Key technical specs:

    • Configuration: Two-stage centrifugal compressor, three-stage axial turbine, and a reduction gearbox.
    • Propeller: 8.5 feet, three-blade, fully reversible aluminum propeller.
    • RPM: At maximum engine RPM (41,730), the propeller rotates at 2000 RPM.
    • Rotation: Left engine rotates clockwise; right engine rotates counter-clockwise to reduce torque effects.
    • Start Latches: Because a feathered propeller creates too much drag for the starter to overcome (leading to overheating), 'start latches' lock blades in flat pitch during shutdown to facilitate startup.

  9. Technical implementation of the Rafale simulation

    The Rafale simulation for Microsoft Flight Simulator (MSFS) uses a custom architecture to achieve high fidelity:

    • Flight Model: The default MSFS flight model is completely overridden by a custom flight control system and fly-by-wire (FBW) logic implemented in WASM. This enables features like automatic terrain following and autothrottle control in angle-of-attack mode.
    • Avionics: Implemented using a hybrid of WASM and JavaScript to balance high-performance system simulation with responsive cockpit displays.
    • Platform: Leverages MSFS 2024 APIs to implement advanced features beyond the original simulator design boundaries.

  10. Operate BD-5 flight controls and pitch trim

    The BD-5 uses classical mechanical flight controls with the flight stick located on the right console. Pitch movement is assisted by an anti-servo tab. Pitch trim is managed via an electric actuator and is adjusted using the handle located next to the throttle.

  11. Technical implementation of the Rafale simulation in MSFS

    The Rafale simulation uses a custom architecture to achieve high fidelity, bypassing several default Microsoft Flight Simulator (MSFS) systems:

    • Flight Model: The default MSFS flight dynamics engine is completely overridden. A custom flight control system and fly-by-wire (FBW) logic are implemented in WASM to accurately reproduce Rafale handling, including automatic terrain following and autothrottle in angle-of-attack mode.
    • Avionics: Implemented using a hybrid of WASM and JavaScript to balance high-performance simulation with responsive cockpit displays.
    • Platform: Leverages MSFS 2024 APIs to implement advanced features that were not possible in previous versions.

  12. Rafale HOTAS (Hands On Throttle And Stick) philosophy

    The Rafale uses a HOTAS design to allow pilots to perform essential flight and combat operations without removing their hands from the throttle and control stick, reducing workload and increasing situational awareness. While most functionality is implemented, some controls may be unavailable due to simulator limitations.
