! Each active data row follows: value  key  - comment

! General
! -------

True            si_unit      - True for SI (m, m/s), False for English (ft, ft/s)
40.000          t1           - transient start time [s]
2               wtc          - wind turbine class (1, 2, or 3)
B               catg         - turbulence category (A, B, or C)
0.000           slope_deg    - inflow inclination angle [deg]
3               iec_edition  - IEC edition for alpha (1 or 3)

! Turbine
! -------

150.000         hh           - hub height [m]
240.000         dia          - rotor diameter [m]

! Operating Speeds
! ----------------

4.000           vin          - cut-in wind speed [m/s]
10.000          vrated       - rated wind speed [m/s]
24.000          vout         - cut-out wind speed [m/s]

! Cases
! -----

! Format: case_type  use_case  options_array  - allowed options and notes
! Set use_case to True to generate the listed options, False to skip the row, or None as a placeholder.
! For NWP, the listed speeds are always interpreted in m/s, matching the legacy IECWind behavior.
