Free Preflight Checklist App for Pilots
AirCheck is a free preflight checklist app that guides pilots through every phase of a pre-flight aircraft check, one tap at a time. It replaces a paper checklist with a clear, phase-by-phase list where each item is confirmed by tap, so no step gets skipped before engine start, taxi, or takeoff.
How it works
AirCheck breaks a pre-flight check into ordered phases such as walkaround, cabin, before start, before taxi, and before takeoff. Each phase shows its own list of items. Tap an item to confirm it, and the app marks it done and moves the focus to the next line. Progress stays visible so a pilot can see at a glance what is complete and what remains. Because the flow is sequential, it mirrors the read-and-do or read-and-verify method taught for standard checklist discipline. A check can be started as a guest, without any account, and run to completion in the browser on a phone or tablet in the cockpit.
Why use a digital preflight checklist
Paper checklists can be lost, torn, or missed line by line under workload. A digital preflight checklist keeps the current item highlighted, prevents accidental skips, and gives clear visual confirmation that a phase is finished. Tapping each item forces a deliberate action rather than a glance, which supports the habit of confirming rather than assuming. The checklist lives on a device most pilots already carry, so there is nothing extra to print or pack. For student pilots it reinforces the correct order of operations, and for experienced pilots it serves as a fast, reliable backup to memory.
Features
AirCheck is free to use with no signup required to start a check. Items are organized phase by phase in the order a real pre-flight check follows. Each item is confirmed with a single tap, and completed items are marked clearly so the remaining steps stand out. The interface is built for cockpit use: large tap targets, minimal clutter, and readable text. A free Yesodi account adds saving, so a pilot can keep and reuse checklists and review past checks. The app runs in a standard web browser, so there is nothing to install.
Use cases
AirCheck suits general aviation pilots running a routine pre-flight before a training or cross-country flight, student pilots learning checklist flow and phase order, and flight instructors demonstrating the read-and-verify method. It also works as a quick backup when a printed checklist is unavailable, and as a consistent routine tool for pilots who fly the same aircraft regularly and want a repeatable, tap-to-confirm sequence every time.
Tips for a reliable pre-flight check
Run the checklist in the same physical order every flight so the habit becomes automatic. Confirm each item by looking at the control or indicator before tapping, rather than tapping from memory. Do not skip a phase even on a familiar aircraft, since routine flights are where items are most often missed. Treat the app as a verification aid alongside the aircraft manufacturer checklist, not a replacement for approved flight documents. Keep the device charged and mounted where it is readable without blocking the instrument panel.
