Either way, in my region you could dispatch by factoring the visibility. If, for example, the destination had HIALS and it was night, the factor would be 2. So 600m becomes 1200m, thus above the minimum of 800m so you can launch.
edited to add that the 1200m is now what we call "equivalent RVR"
Thank you for your opinion.
We also have "equivalent RVR" table.
But There are special conditions for applying this regulation in our company.
* RVR Conversion Table Note
1. This table may not be used for takeoff minima determinations, CAT 2 or CAT 3, or if RVR is available and reported
2. This table may not be used for landing minima determinations on Flight Planning Stage.
3. Equivalent RVR = (Reported Prevailing Visibility) X Factor
anyway many thank you for your reply.
