✈️ GateMaster - Smart ATC Gate Assignment System

GateMaster is a real-time Air Traffic Control (ATC) dashboard that automates airport gate assignments. It uses a Priority Queue (Min-Heap) data structure to efficiently allocate the nearest available gate to incoming flights, optimizing airport operations.

🚀 Features

• Smart Scheduling: Uses a Min-Heap Algorithm to find the soonest available gate in $O(\log n)$ time.
• Real-Time Queueing: Automatically stacks flights if a gate is currently busy.
• ATC Interface: Designed with a "Dark Mode" radar terminal aesthetic for realism.
• Live UTC Clock: synchronized with global aviation time standards.
• Responsive Design: Fully functional on desktop and mobile devices.

🛠️ Tech Stack

• Frontend: HTML5, CSS3 (Grid/Flexbox), Vanilla JavaScript
• Backend: Node.js, Express.js
• Data Structure: Custom Min-Heap Implementation (Priority Queue)

⚙️ How It Works (The Logic)

1. Priority Queue: All gates are stored in a Min-Heap based on their nextAvailableTime.
2. Assignment: When a flight is entered, the system extractsMin() (gets the root node) to find the gate with the earliest free time.
3. Time Management:
   • If the gate is Free, the new flight starts immediately.
   • If the gate is Busy, the new flight is scheduled to start after the current one finishes.
4. Re-Insertion: The gate is updated with the new time and re-inserted into the Heap.
