NOT to be used a primary reference in emergency, this is just some parameters I observed during flights. Always apply the memory items in case of emergency.
For A320 and A321 in clean config: I have been playing a game in my head to try guessing what will be the N1 and pitch when I level off and after many observations I came with the following rule of thumb:
FL300 and above: Pitch 2 and 80% N1 will keep you out of trouble. Adding 1% N1 for every 3000 feet higher in case of heavy weight could be consider: For instance if you are cruising at FL 360, target an N1 of 82%. On the NEO, I noticed the N1 is usually higher compare to the CEO so I would add maybe 1% N1 every 2000 feet instead.
For lower altitude: Minus 1% of the N1 for every 1000 feet works fine also. For Instance if I was flying at FL 250, I would target a pitch of 2.5 and a N1 of 75% then FL 100 N1 of 60% and pitch of 4 degrees.. The pitch I would increase by 1 degree every 10 000 feet.
These are just approximate values I observed. The one at high altitude is pretty much spot on. You can have a look next time you fly. =)
