If you are trying this exercise in the simulator, a good way to feel out the profile is to start at 10000 feet or so directly above an airport, and spiral down. Have your PM run the long QRH (or ECAM if displayed) until too low (3000 feet? Your call). Then convert to the “Sully Procedure” on the back cover.
Profile wise, clean at green dot fly the circuit at about twice the height you would usually be for a given position. For example if you would typically be 1500 feet at 5 miles (300ft / nm), be at 3000 instead and so on. Save the configuration (at least beyond config 1) until you absolutely have it made, and start to feel just a little high. Give each configuration time to settle before selecting the next (you will need to lower the nose more than you think to maintain a safe speed as the drag builds up). The QRH gives a 1.5 : 1 glide ratio fully configured (A321). Give about 1000 feet to crank the gear down. If you are a little high on final, s-turns or whatever it takes to get down. Better a little high than a little low! Find your nonmoving aim point out the window. That does not lie.
