A320 AC 1+2 FAIL
 

In the simulator during takeoff at V1, we had all screens go dark. It was an AC 1+2 FAILURE, I stoped inside the runway, but the examiner said it is safer to continue.
how would you handle this one?

What does your pre departure brief include as reasons to stop after 80 kts? I doubt totally blank EFIS screens is included. You do have standby instruments and skills to use them, don’t you?

That exact failure (ending up in EEC) has been highlighted recently in our latest recurrent check, I think before the discussion most of us would probably have considered a stop to be a good course of action but the problem is that your ability to stop the aircraft is severely degraded, only 2 spoilers per wing, no reverse and worst of all, no anti-skid. You managed to stop but there is a good chance of a high speed excursion on anything but a very long runway.

To stop the a/c you have partial spoilers and acc. brake pressure (7 application ,no reverse ) .
Now you have to think ,as usual , from where you are taking off . It is a 4 km rwy dry ? No problem , but what if you are departing from short wet ,contaminated rwy ? You will be able to stop ? So knowing that you lost both AC bus , ok scaring everything go black , you need to rotate on stanby instruments but after second with the RAT the screen will be back on , get airborne you can reach an holding ,make an assestment , decide if go back to the same rwy or looking for a longer one , perform the approach full briefed on what you miss from sys ,brake, rev. etc. . It is not safer than rejecting without knowing if you will be able to stop before the rwy end ?

Well explained, Nick 1.

And so it should be briefed before the exercise, followed by: "and that is what we will practice during the session."

Training is not hard, if you put the student's improvement first.
