Rvr

[Kevin9009]

Hello guys,

In which of the following circumstances may a conversion between meteorological visibility and RVR not be used?

A. For calculating landing minima
B when operating a multi engine aeroplane whose performance is such that it cannot comply with takeoff performance condition in the event of a critical power unit failure
C when operating a category E or D aircraft
D for calculating take off minina?

AMC10 CAT.OP.MPA.110 Aerodrome operating minima
CONVERSION OF REPORTED METEOROLOGICAL VISIBILITY TO RVR

(a) A conversion from meteorological visibility to RVR/CMV should not be used:
(1) when reported RVR is available;
(2) for calculating take-off minima; and
(3) for any RVR minima less than 800 m.

(b) If the RVR is reported as being above the maximum value assessed by the aerodrome operator,
e.g. RVR more than 1 500 m, it should not be considered as a reported value for (a)(1).

(c) When converting meteorological visibility to RVR in circumstances other than those in (a), the
conversion factors specified in Table 8 should be used.

Light elements in operation .......................... RVR/CMV = reported meteorological
.................................................. ...................... visibility x
.................................................. .........................Day .......Night
HI approach and runway lights......................... 1.5 .........2.0
Any type of light installation other than above ..1.0 .........1.5
No lights .................................................. ..........1.0 .........not applicable
