1. Open Excel or Works Spreadsheet.
2. In A1, type
24.
3. In A2, copy and paste this:
=A1-2*D2*(C2/E2+F2).
4. Fill that down several rows.
5. In E2, type in the aircrafts speed.
6. Fill that down several rows.
7. IN F2, type in the aircrafts turn time.
8. Fill that down several rows.
9. In B2, type in the airport codes for the route you want. (This isn't necessary, but it helps for organizing.)
10. Research that route in AirlineMogul under "Research Route".
11. In C2, type in the distance of that route.
12. In D2, type in a frequency you want for that route.
13. Voila, it calculated your route time!
14. Repeat steps 9-13 for as many routes as you want. Remember that you can't go negative in column A.
This was done hastily. If anybody sees any mistakes, shout at me and criticize me and do anything else you want to do to make me feel miserable.
