An aeroplane is starting a non-precision approach with an MDH of 250ft and minimum visibility of 800 meters. ATC gives threshold, mid-runway and final third RVRs. When may the approach be started?
a. When threshold and mid-runway RVRs are greater than 800m
b. When all 3 RVRs are greater than 800m
c. When the met viz is greater than 800m. RVR is for precision approaches only. d. When threshold RVR is greater than 800m
