There is also a Noise and Track Sub Committee (NTSC) that meets 3 to 4 weeks prior to the main meeting. The agenda for NTSC includes the Quarterly Environment Report which is considered in detail, including studying the noise and track keeping complaints.
Recommendations are made to LLACC on those issues considered to be of importance in seeking to solve difficult technical problems.
NTSC also looks at specific noise and track keeping issues so as to help reduce the impact of flying on the local communities.
The representatives on NTSC are expected to have a detailed knowledge of the specialist issues they discuss so as to help the airport minimise disturbance. That is challenging at a growing airport. Some of the NTSC members can be seen here taking their own noise measurements.
