Hello all.
I’ve heard differing answers to these so wondering if I can get any clarity here.
In in the sim and performing LVTO with HIRL and 15m centreline light spacing minima RVR125m. On take-off rvr given by atc is 1st segment not working then 125/125 for mid and stop end. Our manual says ‘RVR value representative of initial part of take off run can be replaced by pilot assessment’. How many centre line lights do I need to see in from of me? Is it 6 lights ( I.e 90m visual segment from cockpit which my aircraft complied to) or 8.3 lights to give me the 125m?
Lastly before approach ban point you are doing a Cat 3a approach with minima 200/125/75. Then twr give you TDZ RVR is NA/125/75. For cat 3a you need 2 RVR readings avail. Is it legal to complete the approach? The mid and stop are reported and controlling and at or above minima. Or do I need the TDZ RVR minima for the mid i.e NA/200/75.
Also what is meant by controlling RVR?
Thanks,
Mooneyboy
