Default Aero tow cost estimation

The SSA Member Locator works a treat for finding member e-mails, much of the time, if the member keeps the information up to date, and you can guess the real first name if different from the commonly known name.

The USENET used to be the spammers early collection site for e-mails, but after I recently did some updating in LinkedIn, that seemed to cause a huge uptick in spam to an e-mail address which had been clean for years.

YMMV,

Morgan, it's true - large, unexpected costs are a normal part of the airplane ownership experience. Having owned all or part of several airplanes, I managed to get buy by adding 35% to the expected costs to cover unbudgeted liabilities. Sometimes there was an annual surplus, sometimes a deficit but it seemed to average out. But then, maybe I was lucky.



Could you upload your spreadsheet to a public DropBox folder and let us have the link. I kinda hate to put an e-mail address on RAS.

Bill,








I think I have what you are basically looking for. You'll have to adjust the variables for your scenario, but I did this breakdown years ago.








What has continually been a factor outside the ability to capture in a spreadsheet are the unexpected costs. The engine that hadn't been run routinely for the last 10 years or whatever prior to our acquisition and subsequent internal corrosion that resulted in a rebuild at 1200hrs instead of 2000.
