Spandex,
My problem is you saying you have to taxi down a runway first to see a centre line light before you commence takeoff.
A blazing set of Cat3 touchdown lights is superior to just 15m centre lights. We need the 15m centre lights because for some part of the takeoff you will use them. That's why they are needed as a basic minimum. Let me put it another way. Where in EU-OPS does it say you must commence the takeoff from the first 15m centre light ? It says you commence takeoff when you have established a visual cue of 90 m
Do you always use the legally required red stop end lights on a every night takeoff ? No. but must you have them because its a legal requirement yes. Do you always use the standby power system for the ILS ? No. but must you have it because its a legal requirement yes.
You base your performance on a formally declared TODA which is based on particular published holding points. In many cases that has nothing to do with the beginning of the runway threshold hence you would bust your performance with no way to recalculate.
