Airbus ...
Captain 87 ,
don't be so sure that Emergency Proc. on the books are impossible to occur, and that 320 is not like any others aircraft .
Because one of this days maybe you have to learn to flying it like stick and rudder a/c.
If you loose both AC bus during the take off ( image by night) until the Ram Air Turbine pressurize the Blue hyd and emergency generator come online , you are on STBY intruments only.
And i don't think is the right moment to learn some row data handling.
Cheers.
