- 'OB' stands for 'OFF BLOCKS, not 'Start Up', and as kpn syas, ATC are fully empowered to allow start up but if they judge you will not be 'off blocks' by EOBT+/ (stand traffic/lying about a tug/doors still open/you are a slow starter/etc??) they are entitled to ask you to re-file as you may not make CTOT+/.
