Command requires 3500 total hours of which 2000 on AC <12t and 1500 BA hours.
2000hrs on aircraft <25t and 1 year in BA or 1000 P1 on type.
Should there be another 'or' in there. Essentially if you join as DEP (having flown, say, an Airbus for someone else as P2) you need 2000 hours for command. Is that correct? You only need the 3500 if your hours are on smaller things.
Edited to add I think your < should be a >
