LVTO: RVR reduction to 125m

Hey all,

In my company we can reduce the required RVR for LVTO from 150m to 125m (CAT C). Besides certain aerodrome requirements, we need to meet the following condition:

- A visual segment of minimum 90 meters. Airbus states that this condition is met with a segment of 108 meters (provided the RVR is minimum 125m).

Additional requirements are:

- LVP in force
- Lights spacing = CL 15m or less, HIRL 60m or less
- Crew qualified
and
- RVR of 125m at all RVR reporting points. The initial part of the TOR may be replaced by pilots assessment, if RVR not reported.

Here is my problem:
Most of the TREs say that the 90 meter visual segment = the pilots assessment = 6 CL ahead of the a/c (provided they are spaced 15m).

Airbus clearly states (I'm sure that other manufactures do the same) that the 90m segment is ensured, hence the a/c can operate with 125m for TO. With other words the pilots assessment is an additional requirement and needs to be 125m = more than 8 CL.

I'm wondering what your companies requirements are and what your opinion is about the above .

Thanks in advance
