Every hour on the tach is a fraction of an overhaul spent. This tool shows whether your reserve balance is keeping pace with the engine's clock - and the per-hour rate that gets you to TBO fully funded.
A healthy fund keeps the second bar at or ahead of the first. A gap is tomorrow's capital call, quietly growing.
+Reserve discipline
Because the engine wears per hour, not per month. A per-hour accrual charged on every flight means the pilot who flies the hours funds the wear, the balance grows in lockstep with the tach, and overhaul day arrives with a funded account instead of a capital call.
Then the honest per-hour number is higher than the from-new number, because fewer hours remain to spread the shortfall across. That is the "required from here" figure - painful to see, cheaper than the alternative, which is a five-figure surprise split under pressure.
Yes - same logic, smaller numbers. Prop overhauls and avionics refreshes are predictable-ish expenses on long clocks. Resyrv tracks separate accrual rates per component so each fund grows on every flight automatically.
Add your aircraft and your rates, then see the schedule, the squawks, and the ledger all work off one record. No card required.
