How the airport seeks to limit noise impact

Shared and regulated airspace

There are different areas in the sky reserved respectively for civilian aircraft, military aircraft, etc. Sharing airspace like this brings about rules on air corridors.

Pilots are required to comply with the "Air Traffic Regulations" which allow civilian and military aircraft to operate safely every day.

Air navigation services need to adapt to manage this traffic with optimal safety and by trying to reduce pollution; air safety and environmental impacts are the top 2 priorities.

Procedures and trajectories

Aircraft in flight must follow a number of previously defined procedures before they can initiate any manoeuvre or change in their trajectory.

However, some factors, such as the weather, the type of aircraft, its speed or weight, or the safety conditions, explain normal trajectory dispersions in an area around the procedure. Unlike trains that run on rails, planes do not always pass in exactly the same place.

The influence of winds and the use of runways

QFU - Toulouse

Aerodynamic rules require aircraft to take off and land into the wind.

This constraint may explain changes in the direction runways are used at the airport.

By taking off and landing into the wind, the aircraft will "take advantage" of the air mass, either to benefit from a better lift at lift-off or to "slow" its landing.

Runways are built to align with the prevailing winds and the air traffic control services decide in which direction runways are used depending on wind direction and speed.

The two runways at Toulouse-Blagnac Airport are used for both take-offs and landings depending on wind direction and safety and operational constraints.

Special feature at Toulouse: Test flights

Essential for fine-tuning the development of an aircraft and ensuring the future safety of crews and passengers, test flights are a special feature of Toulouse-Blagnac, particularly with aircraft manufacturer Airbus.

To minimise noise pollution:

  • No pilot training flights are conducted at Toulouse
  • A proportion of the test flights have been relocated to Istres
  • On take-off, aircraft have a higher climb rate than a commercial flight
  • The "colour circuit" altitudes are optimised (new aircraft tests and certifications) to reduce the noise impact

Measures taken at the Airport

Several stakeholders are involved in reducing and controlling aircraft noise pollution, each with their own specific and complementary role, responsibilities and areas of action.

Night flight measures

  • Objective: Continue and further the reduction of noise pollution, especially in the dead of night from 12 am to 6 am
  • 5 focal points:
    • Banning noisier aircraft
    • Increasing charges for night traffic
    • Take-off and landing procedures and optimisation of the use of runways in the dead of night, etc.
    • Soundproofing programme for local housing
    • A "Dead of Night” observatory.

The "Dead of Night” observatory

This closely monitors the implementation of the measures with the parties involved, and measures the results obtained.

Under the auspices of the state - Civil Aviation Safety Directorate (DSAC) Chair - the "Dead of Night" observatory is based on a collective approach (public authorities, communities and organisations). The indicators are used to assess the effects of the chosen measures in the most objective way, through simple and understandable instruments.

Toulouse-Blagnac Airport acts as the interface and provides coordination between all the stakeholders, monitoring, measuring and informing local residents about noise pollution via the Sentinel system (noise and flight trajectory monitoring).

Publications

In order to share information on noise and statistical indicators, the airport has introduced publications so that everyone can find out about and understand the context, the measures taken and their outcomes.
