Had my airspace filter set to 6000' recently and in discussion after the flight with a friend, realised that we had been flying at 5500' oblivious to the fact that there was controlled airspace above us; above the 6000' filter.
A suggestion ...
Can we have a warning please when we are flying close to our filter altitude so that we can take appropriate action.
A great application and thanks from me and many others.
