Testing if the system mode lights on the MCDU function when the announciator test light button is pressed. Gave the countless A320 typerating videos on YouTube a break extra to test this… 
Here are some bonus screenshots because afterwards the romantic nightly cockpit was highly enjoyable:
The warmed up kerosene coming from the heat exchanger for the integrated generator disks runs into the wing tip tanks, wonderful how the fuel is so much warmer there compared to the inner wing tanks!
Fun fact: There was a Simpsons character named Apu, and the Ryzen integrated GPU is also called APU ( What Is an APU? A Basic Definition | Tom's Hardware ). So many Apu´s!
Made August 24th to December 24th yesterday, anti cockpit lights out philosophy. Merry Christmas!
