What is this?

This tool tracks aircraft around the airport and visualises the noise impact as a heatmap. It's designed to help evaluate aircraft noise levels at specific locations — useful if you're considering buying or renting property in the area.

Live Tracking

The tool automatically polls for aircraft within the airport's radius every few seconds. All detected aircraft are shown on the map with real-time position, heading, altitude, and speed. Plane icons rotate to show their direction of travel. Dashed trails show recent flight paths, colour-coded by altitude:

• Red — Below 500m above the airport
• Orange — 500–1,500m above the airport
• Yellow — 1,500–3,000m above the airport
• Blue — Above 3,000m above the airport

All data is saved to a local database, so the longer you leave it running, the more comprehensive your noise picture becomes.

Heatmap

The heatmap shows cumulative noise exposure based on all recorded flight data. Areas in red experience the most frequent, loudest overflights. Green areas are quieter. Toggle it on/off from the Layers panel in the sidebar.

Flight Paths

Enable "Flight Paths" in the Layers panel to see individual recorded flight trajectories. These appear at zoom level 11 or closer. Click any path to see the aircraft callsign, type, altitude range, and direction.

Point Analysis

Click anywhere on the map to get a detailed noise report for that location:

• Daily Avg (Leq) — The equivalent continuous noise level, a standard metric for noise exposure
• Peak Noise — The loudest single overflight recorded
• Flights / Day — Average number of flights passing nearby each day
• Hourly Breakdown — Bar chart showing noise by hour of day (local time), useful for identifying night-time disturbance

Noise Level Reference

30 dB	Whisper
45 dB	Quiet residential
55 dB	Normal conversation
65 dB	Busy road
75 dB	Vacuum cleaner
85 dB	Heavy traffic
95 dB	Motorcycle nearby

Filters

Expand the Filters accordion in the sidebar to narrow the data:

• Date Range — Show only flights within a specific period
• Hours — Filter by time of day (e.g. 22:00–06:00 for night noise)
• Aircraft Type — Include/exclude heavy jets, turboprops, helicopters, etc.

Click "Apply Filters" to update the heatmap and flight paths.

Tips

• Leave the tool running for several days to build up a reliable noise profile
• Night noise (22:00–06:00) is often the most important factor for residential areas
• Click multiple locations to compare noise levels across different properties
• Areas directly under approach/departure paths will show the highest noise
