Hi Lord Spandex Masher,
So to confirm what you are saying:
- If you are doing more than 60kts (where'd that come from anyway?) before you reach the 15m spacing you can't carry out a LVTO?
No - I didn't say anything of the sort.
I said I will not be exceeding about 60kts by the time I can see the 15m RWCL lights.
The 60 kts is the RTO speed below which I can ignore stop end RVR reports (if they are below my minimum).
It is assumed we can maintain the runway centre line easily, with reduced visibility, below that speed. Similarly, on take off it is assumed we can maintain the centre line easily (below around 60 kts) with a 90 m visual segment available from the cockpit at the start of the take-off run.
To rephrase the other question you ignored - Does your OPS manual state that you require 15m spacing HI center line lights to perform a LVTO?
I ignored it because the original was a stupid question.
It says "High intensity runway centreline lights spaced 15 m or less and high intensity edge lights spaced 60 m or less are in operation." no more and no less than the current regulations.
