CTOT versus Off Blocks
This evening i watched a BA Shuttle have to taxi back onto stand to refuel after its CTOT was altered several times after push back. I'm not exactly sure but I'd guess a minimum of half a ton of fuel wasted, probably more or i doubt he would have needed more. This is fairly unusual but more likely is the case that we are refused push because of delays at the hold which mean we would not get away within the slot. These delays we have no control over nor are able to see when we're facing the pier.
Would it not be better if, instead of CTOT's we were given Off Blocks Time's.
It would be much easier and straight forward for the crew to manage. Easier for ATC to enforce (no ambiguity), wouldn't be affected by problems with holding point delays at peak periods.
There are bound to be problems with infrastructure since CFMU has grown into a huge business since the 'good' old days where we used to phone the regulator and speak to a Controller with half a dozen clip boards in front of them but is it possible and does anybody agree it would be better.
