When to consider Jet engine Spooled down
I fly an A320. At parking beacon was turned off as soon N1 reached 5% or had amber crosses. Now the FCOM changed to turn beacon off when engine has spooled down. I'm trying to find what is the exact meaning of spooled down, as soon as you switch it down? As soon as its stopped? N1, N2? When should a jet engine considered spooled down for safety issues?
