NREL 5MW reference turbine max platform pitch angle

Hi,
WT have a maximum pitch angle, which is OEM-specified, and is usually around 7-10 deg.
What is the max pitch angle of the NREL 5MW reference WT?
I tried looking for it in the DISCON_OC3 source code, but there is no shutdown routine for large platform pitch angles

I also read the research paper of the turbine, as well as many other related, but I was unable to find this data.

Dear Gustavo.Hylander,

The maximum heel angle of the NREL 5-MW baseline wind turbine has not been specified. You’ll have to make your own assumptions for your own purposes.

Best regards,
