What "status"?
In-Air/On-Ground?
Configured for takeoff? Taking Off? Completed Takeoff? About to Land? Landing? Landed?
There are already various aircraft systems which use various of these conditions - config warnings, EGPWS, Ground Spoilers, and so on.
If you tell us what exactly you want, it may be there's already a clever bit of logic on the plane doing it for you.
