WinCtrl ICP

Overview

This application provides a fallback ICP display for the WinWing/WinCtrl ICP controller, delivering useful avionics data in Microsoft Flight Simulator (MSFS) and X-Plane when aircraft are not officially supported by WinWing/WinCtrl.

Many aircraft expose rich avionics data through SimConnect, FSUIPC, or X-Plane datarefs but display no information at all on the WinWing/WinCtrl ICP unless explicitly supported by SimAppPro.
This project fills that gap by presenting a common, aircraft-agnostic ICP display that works across all aircraft.

SimAppPro is not required.

Purpose

The goal of this application is simple:

  • Ensure the WinWing/WinCtrl ICP always shows meaningful information.

Rather than relying on aircraft-specific integrations, the app exposes a Common Navigation Information (CNI) display and related pages—an aircraft-agnostic abstraction inspired by, but not limited to, the F-16’s Communications, Navigation, and Identification concept—that every aircraft can support.

Built-In Displays

The following displays are included out of the box:

  • CNI – Common Ntrument Information (primary overview)
  • COM1 – COM1 radio status and frequencies
  • COM2 – COM2 radio status and frequencies
  • IFF – Identification / transponder information
  • NAV1 – NAV1 radio and information
  • NAV2 – NAV2 radio and information
  • GPS – GPS waypoint information
  • AP – Autopilot derived data
  • SWCH – Switch states
  • LGHT – Light states
  • WX – Weather (OAT, wind, pressure, QNH)
  • TIME – Time and location
  • INFO – System and position information
  • HROT – Helicoptor rotor systems
  • HDIS – Helicoptor dynamics and instruments
  • HCTL – Helicoptor flight controls
  • BALN – Balloon envelope, burner, vent, and thermal status
  • AIRS – Airship gas compartment, pressure, volume, weight, and mast systems

Each display is:

  • Aircraft-agnostic
  • Hardware-accurate in layout
  • Consistent in units and formatting

Custom Displays

In addition to built-in displays, the application supports user-defined custom ICP displays.

Users can:

  • Create custom layouts
  • Select from all available avionics and system fields
  • Control positioning, inversion, padding, and formatting
  • Build displays without modifying application code

This allows the ICP to be tailored to individual workflows or aircraft while still using the same data backend.

Joystick & Button Mapping

Joystick button mapping is supported for ICP display control only.

Buttons may be mapped to:

  • Select a specific built-in display
  • Select a custom display
  • Cycle forward or backward through displays
No simulator control inputs are generated.
Button mapping exists solely to control which ICP display is shown.

Simulator Support

  • Microsoft Flight Simulator (MSFS)
    • SimConnect
    • FSUIPC
  • X-Plane
    • Native datarefs
The provider-based architecture allows additional simulators to be added if desired.

Units & Globalization

The application supports multiple unit systems:

  • Aviation (ft, NM, kts, °F, inHg)
  • Metric (m, km, km/h, °C, hPa)
Raw values are preserved internally, with formatted values derived consistently for display.
This ensures accuracy for both gauges and human-readable output.

Altitude Modeling

Altitude values are intentionally separated to avoid ambiguity:

  • MSL – Indicated altitude based on Kohlsman setting
  • AGL – Height above ground level
  • TALT – True altitude derived from actual static pressure
This avoids misleading “everything matches” behavior and keeps preview data meaningful.

Bridge Architecture & Reliability

The application uses a lightweight external bridge process to communicate with the WinWing/WinCtrl ICP.

Features include:

  • Automatic launch and connection
  • Service-style crash recovery
  • Limited restart attempts to prevent runaway failures
  • Graceful fallback when the bridge is unavailable
If the bridge is down, the application continues running safely without attempting to write to the ICP.

What This Application Is Not

  • Not a replacement for aircraft-specific SimAppPro profiles
  • Not a study-level avionics simulation
  • Not tied to any specific aircraft
It is intentionally generic, predictable, and robust.

Status

Actively developed and used.

Built to solve a practical problem:
Flying aircraft with a dark ICP despite the simulator providing all the necessary data.
