INM 6.0a includes data for three new aircraft, including the:
  • Airbus A340
  • Embraer 145LR
  • Embraer 120

Corrections
The program makes a change in the calculation of the EPNL, NEF, and WECPNL metrics. This correction was unique to INM 6.0 and does not affect the A-Weighted metrics such as DNL and CNEL. A complete description of program additions, corrections and installation instructions is provided in the inm60a.pdf file below.

New Features
The program was enhanced to provide faster loading of contour files and to allow access to helicopter spectral classes.
