When AerScheduler grounds an aircraft by itself

One switch, one behavior#

Every recurring and one-off inspection carries a Grounds the aircraft switch. With it on, the day that inspection comes due:

• The aircraft is grounded with the reason Maintenance.
• Every booking type except maintenance is refused on it with "Resource is grounded."
• The tail sorts to the top of WebMaintenance → By aircraft with a Grounded badge.
• The inspection row itself carries a red Grounds flag in the work queue.

With it off, the inspection still comes due, still shows as overdue, and still notifies your admins and technicians. The aircraft simply stays bookable.

Turn it on for an inspection#

The switch is on the Recurring and One-off forms in WebMaintenance → Add inspections. Afterwards it shows as a red Grounds badge on the rule's row under WebMaintenance → Set up.

Which of the standard inspections ground#

Of the seven AVIATES presets, exactly two: the Annual inspection and the 100-hour inspection.

VOR check, Airworthiness Directive review, transponder check, ELT, static system and altimeter, oil change and ELT battery replacement all come due without grounding anything.

What an automatic grounding looks like#

The same as any other grounding, with one tell: the reason reads exactly "Maintenance" rather than something a person typed.

An hour-based grounding waits for a close-out#

Calendar inspections come due on their own, around the clock. Hour-based ones do not: the countdown only moves when a flight is closed out on that aircraft, and the grounding happens at the same moment.

So a 100-hour that is already past due on screen will not have grounded the aircraft yet if nobody has closed out a flight on it since. Correcting the tach by hand under WebAircraft → the tail → Edit does not trigger it either. More on this in Troubleshooting inspections and squawks.

Coming back off the ground#

Sign the inspection off and the aircraft returns to service by itself, as long as nothing else is still holding it. Every overdue inspection on the tail counts, not only the ones that ground, so an overdue oil change will keep it on the ground until that is signed off too.

Deleting the rule, or detaching that tail from it, clears the grounding the same way.

Reminders created during setup all ground#

The maintenance step offered while you are setting the school up creates every reminder as a grounding one, including the oil change.

If you set your fleet up that way, open WebMaintenance → Set up afterwards and look at which rows carry the red Grounds badge. An oil change taking a trainer off the line mid-morning is the support email this causes.

The switch defaults differently on web and on the phone#

Check it before you save, wherever you are.
