ED Decision 2022/012/R
MEANS TO DETERMINE THE REQUIRED RVR BASED ON DH AND LIGHTING FACILITIES
(a) The values in Table 2 are derived from the formula below:
RVR (m) = [(DH/MDH (ft) x 0.3048)/tanα] — length of approach lights (m),
where α is the calculation angle, being a default value of 3.00° increasing in steps of 0.10° for each line in Table 2 up to 3.77° and then remaining constant. An upper RVR limit of 2 400 m has been applied to the table.
(b) The lighting system classes in Table 2 have the meaning specified in Table 6.
