What might be useful would be to have maybe on the operations page a single bar that is split into a red and a green and has a 50% mark, the red would be Projected expenditure and the green would be projected income, if the green bar extend beyond the 50% mark then you know you will make a profit at the end of the month if the red bar crosses the 50% mark you know you will make a loss. So basically it will show if the total amount of money coming in is equal or not to the total amount going out. this would be useful because it the finance page is not always clear. if you can do this also it would make it even better, if you mouse over either colour it gives you the break down of the money, So for green it would be Aircraft revenue (minus fuel costs etc) Meal Revenue, lease revenue, sales revenue etc and a total. and for red it would be Aircraft expenditure, Aircraft maintenance, Gate rent, Wages, Purchases, Lease expenditure, etc and a total. If this is possible the it would be good that if you have expenditure that exceeds the income then tips could be given.
Another graph that might be useful is one that shows the usage of your planes, probably a Pie chart would be best. So the categories for it would be, On Order, Not in service, Under 5 hours in service, 5-10 hours in service, 10-15 hours in service, 15-20 hours in service, 20+ hours in service. (planes on order would not count as not in service)
