Please add the "IsFlying" and the "Airspeed" parameter as selectable value in the remote. It's much better to connect any inflight warning with this parameter so you don't get an alarm all the time when the plane in on the ground.
e.g.: "Stall warning alarm" if ("Airspeed" < "still safe airspeed") AND ( "Isflying" = 1)

I do this via the logical switches in OpenTx
