Loan mechanics question - possible bug?

[Sanabas]

From reading the manual, it seems that an unsecured loan, or an airline that is past its unsecured limit and taking out a new secured loan, should have the bank demanding a higher margin than a fully secured loan. I'm playing in the beginner world, the first unsecured loan I took out was at 12.5%, 6% for the current interest rate + 6.5% margin for the bank. My next loan was fully secured, same deal.

Having fiddled around with things, I have paid the unsecured loans off early, and now my financial situation is that I have ~320 million worth of owned planes, ~130 million worth of fully secured loans, ~210 million airline value (not sure where the ~20 million discrepancy comes from), making 6-10 million a week operating profit on 30+ million of ticket sales. However the bank won't offer me any unsecured loans, only ~200 million worth of secured loan, and still at a 6.5% margin.

If I reached the exact same financial situation I'm in currently by only taking out secured loans, I think I'd have a very different picture when seeing what the bank's prepared to offer. It seems that if all loans are paid off, the bank will reassess, and offer you unsecured loans (this I tested early in the game) and also offer you a lower margin on fully secured loans (this I'm yet to test). But that simply paying off all the unsecured debt doesn't cause anything to change, even though it should.

Currently, the only thing that secure loan does is increase overall credit availability.  The loans go from the same pool.  So, theoretically, if the unsecure limit is 100 mil, secured limit is 200 mil and you have no loans outstanding, you can take first unsecured loand for 100 mil, and second secured loan for 100 mil.  But if you take your first loan as a secured loan, the second loan will only be available as a secured loan...

You would think that you would have a lower margin with secured loan.  But no, you don't currently in AWS.  The only thing that lowers the margin is if your credit rating improves.

As far as credit rating, 2 components go into it: time, and company value.  If your company value goes up, your credit rating improves.  But the time our company is in business is also a limiting factor.  A new company will not get an AAA rating.  You have to be in business, probably some 10 years to get to AAA....

I'd say you have (well, had at the time of writing) about 20M in pure good old cash

Value = Owned planes + cash - loans.

Completely forgot about cash on hand.
