Environmental Monitoring System

As part of the requirements specified in NMP 2/4 an environmental monitoring and aviation enforcement system was established within the IAA, with its deployment and operation being set by the Minister of the Interior, the Environmental Protection Minister, the Transport Minister and the Minister of Health or those parties certified by him.
The systems' roles include the collection of noise and pollutant data and processing it in reports in order to determine the eligibility for acoustic shielding, to enable the operation of the professional committee, to enable the operation of the public committee, and to monitor operation patterns and operation limitations set in the NMP. This monitoring system is managed, operated and maintained by the Environmental Department of the Planning and Engineering Division in the Israeli Airport Authority, under the control of an authorized public officer.
The system is built from two separate monitoring systems: an air quality monitoring system and a system for monitoring flight routes.

The Air Quality Monitoring System

Consists of two monitoring stations that monitor the concentration of pollutants. These stations are linked to a computerized control center which contains two work stations.

The system monitors three pollutants:

Nitrogen Oxide (NOX)
Tropospheric Ozone (O3)
Fine Respirable Particles (PM2.5)

The monitoring system continuously samples the air, conducts physical and chemical analyses of these samples, and sends the results to a database from which the required reports are produced.

Each one of the monitoring stations is linked to an independent meteorological substation which transmits information regarding four meteorological parameters in parallel and in real time: wind direction, wind velocity, temperature and relative humidity. These parameters have a great effect on the monitored aspects of air pollution, and are also stored in the database at the system’s control center.
Both the system’s specifications and its construction were done in complete coordination with the Ministry of Environmental Protection. The operation of the system, its maintenance, and the production of reports are all done according to the standards which the Israeli Airport Authority must meet as set forth by the definitions provided by the NMC (National Monitoring Center) at the Ministry of Environmental Protection.

 

Noise Monitoring and Route Tracking System
Monitoring stations measure noise levels and transmit noise events they pick-up in real time to a central computer system located at the IAA, alongside the airport’s radar readings, thus correlating between the flight and the noise it created.
The aircraft noise policy implemented in the BGAP area is supposed to demonstrate a balance between (national) aviation needs and (local) public needs. Of all the aviation needs, the need to maintain flight safety regulations and provide aviation services at a proper level should be emphasized. Of all the local public needs, the commitment to minimizing the noise originating from aviation related activities should be emphasized. When formulating the policy for minimizing the noise the following aspects should be kept in mind:

The limitation of take offs during night time
Activating a preferable operating patterns (limiting the use of runways and lanes)
Limiting aircraft models according to the level of noise each one produces
Limiting land activity (positioning aircrafts, running engines)
Acoustic shielding
Activating the noise monitoring and route tracking array
