New: Calculation method ICAN (AzB 2008) implemented! more
With Option FLG noise emitted from civil and military airports is calculated based on the calculation methods ICAN (AzB 2008), AzB (old), ECAC Doc. 29 or DIN 45684-1. With these calculation methods Option FLG covers all procedures for aircraft noise assessment relevant at European and international levels. Option FLG can be applied, without any restrictions, to calculate the noise protection areas around civil or military airports as legally required.

 
The calculation of aircraft noise with Option FLG is equivalent to the calculation for other types of noise like industry, roads, and railways. This means that in examining the total noise e.g. for the calculation of noise maps the aircraft noise immissions can be seamlessly integrated in the overall assessment.

• Calculation of noise contours around airports according to ECAC Doc. 29 (EC interim method)
• Calculation of aircraft noise according to guidelines AzB 2008, AzB (old) and DIN 45684-1
• Overall assessment of the total noise load including industrial, road, railway and aircraft noise
• Accurate calculation of noise protection areas around civil or military airports

• Calculation of aircraft noise at predefined receiver points and on a grid
• All relevant international methods implemented (AzB, ECAC Doc. 29, DIN 45684-1)
• Calculation of noise contours for the noise indicators L_den and L_night
• Library with predefined aircraft groups (aircraft and helicopters)
• Import of flight traffic data via ODBC-connection
• Completely implemented into the CadnaA user interface
• Can be combined with all other noise types (industry, road, railway)
