1) What is the difference between RVR and Visibility? 2) In which situations may it happen that the controller gives a visiblity info? 3) In which situations RVR is not availible? 4) Why is the factor during the night higher than during the day? That doesnt make sence because at night it is more difficult to see the runway? Or is the factor higher because of the approach lights?
Depends the state the operation is carried out and the the approach lighting system. HIALS ( High Intensity Approach Lighting System ) , givess the intencity of the lighting greater than 5.000 candles . However the System used , such FALS - IALS -BALS-NALS , is the factor that counts in order to apply according ICAO , Aerodrome Operating Minima doc 8168 . For DGCA ( India) Crew Air Regulations , flight crew is not allowed to apply CMV , with all the above factors you mention , plus the ALS has to be minimum 420 mtrs of length and that falls into to category of NALS. We often use CMV , since during the Monsoon period the only method to plan and land especially at night , with these adverse weather condition is only to apply , CMV. Happy Landings Cpt. All the Best to this spectacular work you do . Very efficient !!!!! Looking forward for more videos !!
Thank you for sharing. Do you mind explaining this example that confuses me? When the airport rvr equipment is not available, for the approach procedure with Cat I landing minimums is RVR550m or VIS800m, if light is HIRL, can approach when VIS is 400m?
Captain Gabrielle, for a CAT 1 landing , the visibility should be 800m, the RVR 550m and the decision height 300 ft. Are you saying that CMV can be applied only if atleast CAT 1 landing minima conditions are met?

I think the restriction of 800m is not aplicable anymore, now is LVO and I think LVO is 550m or less...😊
Hi, thanks for watching in many operators OMAs it is still a requirement. Many thanks for your feedback

Hi, I made a video about RVR, check it out.. Yes at night it is easier to see the lights.

Great comment!! I'm glad to see a colleague in the community!
@@PILOTCLIMB happy landings Cpt. All the best
good explaination sir thanks
FANTASTIC VIDEO
Thanks for watching
Can ATC controller or the meteorological observer do these calculations and pass them to the pilot
Thank you Captain ..i have learned something new today
Great! You are very welcome!
Nice explanation
Many thanks for watching
Thanks for your video, question, so the CMV is done form de visibility given by ATC and not from METAR or ATIS ?
Thank you!
You are very welcome!
New to me; thanks for sharing.
You are very welcome!!
Wonderful
Thanks for watching!

You are very welcome! when the minima is expressed also in VIS the visibility must be at or above that value.

Cat 1- 200 ft. Only cat 1
For any approach with a Minima of 800M RVR or higher...
