Well, yes that would be worst case (maintenance wise anyway). You seem to get all bent out of shape every time someone suggests you need to budget for an engine at some future point. Maybe youre independently wealthy and can just write a check for a new engine. Great, but it still is a future operating cost. Sooner or later you will have a large spike in your yearly operating cost when you overhaul / replace the engine that will skew your yearly average.
Very good original information tho, since I'll likely be in that boat in the future
Not "bent out of shape". Just not the way I do math or manage my assets. That is why I don't see the value to the number.
I have asked for others to provide a number with the related math, so other viewers of the thread could see what works for them.
(As a second aside, there is a strange phenomenon at POA for people to try and discourage airplane ownership. When I first started looking for a 182, I posted a thread and stated what my budget for purchase was. I was then told I couldn't afford to buy a plane as my budget didn't include a bunch of imaginary non-purchase items.
This made no sense to me, as for the purchase, I drew an arbitrary line on what my "toy/tool" budget was for a plane and was comfortable spending that. And, if the value drops to $0 tomorrow, I would not lose sleep or end up in a soup line.
I guess, as we buy planes, we should all look at 3 budgets.
- Purchase/acquisition Budget
- Annual and hourly budget
- Reserves and "Imaginary" Coffee Cans
The first one was solely dependent upon myself, and what I wanted to spend compared to a Toy or a Tractor, or a Trip to Europe. It really shouldn't influence other people's decisions on their case.
The second one is the one I captured in the OP, and can certainly be compared to other people's experience for operating each year.
The third one depends on random luck, risk tolerances, and global events that are outside of much of our control. With quite a bit of influence from the original Purchase Budget. But, it is completely unique to each person and plane combination.)
