A320/321 Operation in the UK
1. No, only check waypoints against plog & enter wind data where sig difference from last waypoint.
2. No, only when carrying out a 'Manual' Start. Infact it is frownded upon to have hand on engine masters for a normal start.
3. Checklist says 'Checked' but often pilots say "Packs On, feed by Apu/Engines or Packs Off"
4. No, only with Ecam message.
Hope that is of some assistance.
