My Aircraft - possible changes and additions

[JumboShrimp]

Financial view:
- change aircraft value to depreciation for owned aircraft
- add filter: Owned, Leased, both
- add totals (not sure how it can work with pagination, but grand total, rather than page total would be useful).

Question this can answer:
- what the cost of my aircraft (by fleet, base etc, using other filters)
- how much is my aircraft earning (total of prev. week profit - by base, fleet etc.)
- what is my LF per base, fleet type etc. (total line would have average for LF)
- what is the total of my lease payments by fleet group
