In General Pilot Documentation Requirements we can find the following position:
- A narrative or statement acknowledging that both surface reflection and visibility of any surface 3 frit patterns have been taken into account.
Could someone please clarify what does it mean exactly, how and were should it be taken into account and how to prove that? Which 3 frit patterns they are talking about?

I have this same question. What does the "3 frit patterns" to be included in the narrative mean?

Hi, Samantha and Maciej; I think the key reference here is "surface 3 frit patterns", not "3 frit patterns". If frit patterns are placed on surface 3 instead of surface 1 or 2, then visibility of the frit may become somewhat compromised if surfaces 1 and 2 introduce highly reflective or tinted "foreground" conditions, potentially reducing the visibility of the pattern and the contrast ratio between frit and glazing. Low-e coatings on surface 2 have the potential to do this, for example. The narrative should acknowledge that you took foreground impacts into account in case you have frits on surface 3 in your collision deterrent glazing assembly.
