SwiftUI Primary Flight Display Simulator ✈️

A realistic Primary Flight Display (PFD) simulator built entirely with SwiftUI. This app replicates the core instruments found in modern aircraft cockpits, using real device motion data to simulate pitch, roll, and heading.

🎯 Features

Attitude Indicator

• Sky & Terrain - Dynamic blue sky and brown terrain with smooth transitions
• Pitch Ladder - Graduated pitch lines at 2.5°, 5°, and 10° intervals
• Horizon Line - Clear white horizon reference

Bank Angle Indicator

• Scale Ticks - Markings at 0°, 10°, 20°, 30°, 45°, and 60°
• Rotating Pointer - Real-time bank angle indication with split-triangle design
• Fixed Reference Triangle - Static top marker for reference

Heading Indicator (HSI)

• Magnetic Heading - Uses device magnetometer for real compass heading
• Rotating Compass Rose - Degree markings with dynamic text labels
• Fixed Lubber Line - Center pointer with top triangle marker

Aircraft Symbol

• Center Reference - Fixed aircraft wings symbol
• Center Marker - Black square with white border at horizon center
