Another UK A320 Operator:
1. Check SID agrees with chart, check en-route waypoints only (and enter significant winds*), check expected STAR against chart
2. No (but I do as airmanship!)
3. Not c/list item so not applicable as normally Flexing to close on max anyway with packs on (luxury, I know)
4. Brake fans not fitted to our 320-100 and -200CFM fleet so can't - does concentrate the mind on hot summer days, both on landing and taxi-out on 40 minute turnarounds. On brake fan equipped -IAE enginedaircraft, will usually not switch on (unless very high/mismatched temps) until at least 3 -5 minutes after landing to allow temps to stabilise and just before turning onto stand (so as not to eject brake dust onto ramp workers for Health and Safety reasons. If aircraft nightstopping then will tend to leave fans off to aid optimal brake cooling. Fans, when used, usually switched off prior to vacating flight deck/before transit walkround/when below 150C/when remembered!
