Hi skyeurocapt,
That sim scenario is unrealistic in it's failure. You did a flight control check on taxi out. The chance of both load paths jamming on the take off roll is so remote you don't need to do any non standard 80kts checking. The sim fault would presumably be inserted at a higher speed.
I suspect the sim examiner was looking to see if you appreciate your performance, by the experience you have gained, of what the remaining runway looks like at V1. If your runway was infinitely long, then your maximum V1 would be much higher than the one you had bugged. Once you had identified the control jam, the options were :
1) to attempt getting airborne using some untried and not recommended method, or:
2) to realise there was sufficient runway ahead to sensibly attempt an RTO.
I think the sim examiner was seeing if you would sit at a set of broken red traffic lights all night, or proceed with caution when you had realised the problem. I'd say you made the right decision.
