Just have an idea of the pitch and power you need, it’s not rocket science. Plus on Airbus the thrust would be locked so you don’t even need to worry about it unless you are in a climb or descent.
A320: Above FL 300: 80% N1 pitch 2 degrees up
between Fl200 and Fl300 : 70% N1 & same pitch
Below Fl200 60%: N1 pitch 3 degrees up then 4 up below Fl100.
Just some rough value from what I saw during flights. With these I might climb or descent gently but I won’t stall nor overspeed and it gives me time to reach the QRH to do fine tunning.
