DCS F-4E TACAN HSI Display Simulator

🎯 Purpose

This simulator replicates the F-4E Phantom II's TACAN HSI (Horizontal Situation Indicator) display for navigation training and practice.

🎮 Controls

HSI Knobs:

• Heading Knob: Adjust aircraft heading with +1°, -1°, +10°, -10° buttons
• Course Knob: Set desired course/radial with +1°, -1°, +10°, -10° buttons
• Knob Animation: Knobs rotate when clicked and accumulate rotation

Simulation Controls:

• START/STOP: Begin/pause aircraft movement simulation
• RESET: Return aircraft to center position
• Speed Control: Adjust aircraft ground speed
• TRAINING: Progressive training mode for step-by-step learning

Canvas Interaction:

• Drag Aircraft: Click and drag the F-4 (blue) or target (red) to reposition
• Screen Wrapping: Aircraft reappears on opposite side when leaving screen
• Breadcrumb Trail: Green trail shows aircraft's flight path

🎓 Training Mode

The Training button provides a progressive learning experience:

• Step 1: "Enable Training" - All elements visible (starting position)
• Step 2: "Show Bullseye" - All elements hidden, practice basic orientation
• Step 3: "Bullseye + F-4" - Bullseye map visible, add aircraft reference
• Step 4: "Bullseye, F-4 & Fix" - Add aircraft, practice navigation basics
• Step 5: "Show All" - Add fix helper for complete navigation training
• Step 6: Returns to full display with all elements visible

Training Tip: Use this mode to gradually build your navigation skills, starting with basic map reading and progressing to full HSI interpretation.

📊 HSI Display Elements

• Compass Ring: Rotates to show current aircraft heading
• Course Arrow: Shows selected course/radial
• CDI (Course Deviation Indicator): Shows deviation from selected course
• Heading Bug: Triangular indicator showing current heading
• Aircraft Symbol: Center reference point
• Fix Helper: Visual aid showing bearing to target/waypoint

🧭 Navigation Concepts

• TACAN: Tactical Air Navigation system providing bearing and distance
• Radial: Magnetic bearing FROM the TACAN station
• QDM: Magnetic bearing TO the station
• HSI: Combines heading and navigation information in one display
• Bullseye: Reference coordinate system for tactical navigation

⚡ Features

• Real-time HSI simulation with rotating elements
• Interactive knob controls with visual feedback
• Aircraft movement with realistic physics
• Progressive training mode for skill development
• Breadcrumb trail for flight path visualization
• Screen wrapping for continuous simulation
• Drag-and-drop positioning
• Bullseye coordinate system integration

🎯 Training Tips

• Start with Training Mode to build skills progressively
• Practice intercepting specific radials
• Use the CDI to maintain course
• Observe how heading changes affect the HSI display
• Try different approach patterns to the target
• Use the Fix Helper to understand bearing relationships
• Practice bullseye coordinate navigation
