Talking for the A320 Family.
“ I would rather fly a 75, But I’m flying an 321”.
An mnemonic to remember the 75321 rule.
7 nm from FAF: Flaps 1
5 nm: Flaps 2
3 nm: Gear down
2 nm: Flaps 3
1 nm: Flaps full.
Works really well. I personnaly put the gear after flaps full at latest as possible as dragging the aircraft fully configured in level flight is painful to watch.
If you do Final Approach Mode, decelerated approach is recommended.
