Activity timeline

06:00–18:00 UTC

Select a track on the timeline or in the flight log to inspect it on the map.

The selected flight day is shown by default so individual tracks remain readable. Choose a timeline block or flight-log row to highlight one track and inspect its altitude below the map; use All tracks to see every route. On a selected track, arrowheads show recorded travel direction and the black marker follows the selected published point. Play steps through published positions at an even viewing pace; it is not a real-time reconstruction. Route density overlays every published track once, so darker corridors were recorded more often; it is not a noise measurement. The bright gold marker indicates the landing site at Orrell Hill Lane, Ince Blundell. Times and durations are based on the visible transponder-derived track, so they may not exactly match takeoff or landing.

What this records

Inclusion rule

Included

A flight is included when a helicopter or rotorcraft is first seen within about 5 km of the Orrell Hill Lane landing site, may travel away on a wider loop, and is then last seen within the same area. It must also show meaningful movement, or both a clear recorded altitude change and movement above taxi speed. Most included tracks are complete round trips from the site; some are single arrival or departure legs whose other end lay beyond reception.

Excluded

Aircraft passing through without starting or ending near Orrell Hill Lane, recordings cut off mid-flight, and stationary transponder bursts that do not show meaningful movement or a clear altitude change.

About this site

Background

Commercial operation

The flights from this site are commercial pleasure flights sold to the public, advertised and bookable online as "Liverpool Helipad" flights through Adventure 001 and resellers. This is not occasional private use — it is a recurring, ticketed commercial operation beside a residential village.

History

Residents have been raising concerns about helicopter operations from the Orrell Hill Lane site since at least 2018. Complaints have been made to Sefton Council, the Civil Aviation Authority, and through the local MP. The issue has involved multiple operators and aircraft over the years. Despite repeated engagement with all available authorities, no resolution has been achieved.

How It Works

Data collection

ADS-B transponder data

The aircraft shown here broadcast ADS-B (Automatic Dependent Surveillance-Broadcast) or related transponder data, including altitude and identity. Some broadcast their own satellite-derived positions; others carry Mode-S-only transponders, whose positions are reconstructed by multilateration across a network of receivers and are less precise. These radio signals are publicly receivable by anyone with a suitable antenna, and this is the same class of data used by flight tracking services such as Flightradar24 and ADS-B Exchange.

Automated logging

A local receiver logs the position of monitored aircraft every three seconds. A published flight must be a helicopter or rotorcraft whose visible track starts and ends within about 5 km of the Orrell Hill Lane landing site, and must show either meaningful movement or a clear change in barometric altitude accompanied by movement above taxi speed. Stationary ground transmissions remain in the preserved source record but are not presented as flights. When the position signal is lost for more than two minutes the track is closed; brief mid-flight dropouts are bridged rather than counted twice, and a recording cut off mid-flight is not published.
