Calculators for Instructors and Small Flight Schools
Free tools for the two questions every small flight school argues about: what an hour of dual actually earns, and when a student will really be ready.
Flight training runs on two scarce things, airplane hours and instructor hours, and both get misjudged in the same direction. Rates get set from what the school down the field charges rather than from fuel burn, reserves and the ground time nobody invoices. Checkride dates get promised from optimism rather than from lessons flown per week after weather cancels a third of them.
These two calculators are deliberately plain. Change the numbers to match your own operation, read the result, and use it in the conversation you were already going to have with a student, a partner or an aircraft owner. Nothing is stored and nothing is required to use them.

How Many Weeks From a Practical Test
Turn hours flown, lessons per week and your local examiner wait into a date you can actually defend to a student.

The Student File Audit Checklist
Work this list once per student per stage and no examiner will find a gap you did not already know about.
Why these calculators are open with no sign up
Instructors already do this arithmetic by hand, usually in the wrong place at the wrong hour. The wet rate gets rebuilt on the back of a weight and balance sheet while the engine cools. Night landings and cross country legs get added up in the margin of a logbook page the evening before a recommendation is due. Weeks to a practical test get guessed out loud on the ramp, from an hour target and a hope about the weather. None of that arithmetic deserves an account, a password reset and a trial clock in front of it.
So both tools stay open. Nothing is stored, no address is asked for, and the numbers hold up whether or not you ever open PreflightLog itself. A contribution figure per dual hour will settle a leaseback conversation with an aircraft owner on its own terms. A defensible week count will stop a student booking a designated examiner three months before the file could possibly be closed. If they only ever do that much for you, they have earned their place on the site.
The number is the easy half
Knowing what a dual hour clears, or how many weeks a student is from a practical test, only helps if the answer survives next Tuesday. PreflightLog keeps those inputs current for every student on the roster instead of asking you to rebuild them one conversation at a time. Ask for a demo and watch the readiness column do it across a dozen files at once.
