ATC Monitor – Air Traffic Simulation Dashboard (Qt + C++17)

ATC Monitor is a desktop application built with Qt 6 and C++17 that simulates a simplified air traffic monitoring system:

• 2D radar display (custom QWidget) with moving aircraft
• Detailed flights table with sorting and conflict filtering
• Conflict detection between aircraft based on configurable distance threshold
• Background simulation in a worker thread
• Event log for conflicts and simulation lifecycle
• Simple settings dialog + persistent configuration (.ini file)
• Basic unit tests for the conflict detection logic

Features

• Radar View

  • Custom QWidget (RadarView) painted with QPainter
  • Normalized coordinates based on latitude/longitude
  • Aircraft in conflict highlighted in red

• Flights Table

  • QAbstractTableModel (FlightsModel) holding Flight structs
  • Columns: ID, Latitude, Longitude, Altitude, Speed, Heading, Status (OK/CONFLICT)
  • QSortFilterProxyModel (FlightsProxyModel) for:
    • column sorting
    • "Show conflicts only" filtering

• Simulation

  • DataGenerator runs in a separate QThread
  • Internal QTimer ticks at a configurable interval
  • Generates and updates a set of flights with random positions and headings
  • Emits flightsUpdated(std::vector<Flight>) to update the UI

• Conflict Detection

  • ConflictDetector – pure C++ module
  • Checks pairwise distances between flights and flags conflicts under a threshold
  • Threshold is configurable from the settings dialog

• Logging

  • QTextEdit used as an event log
  • Events logged:
    • Simulation start/stop
    • New flight entering the radar area
    • Flight leaving the radar area (if implemented)
    • Conflict detected / resolved

• Settings & Persistence

  • SettingsDialog to configure:
    • Number of flights
    • Conflict distance threshold
    • Simulation update interval (ms)
  • AppConfig + AppConfigManager use QSettings with an .ini file
    • atcmonitor.ini stored next to the executable

• Tests

  • Qt Test–based unit tests in tests/
  • ConflictDetectorTests covers basic scenarios:
    • no conflict
    • single conflict
