The "Check Airspaces" feature currently disregards airspaces' altitude limits when creating the list of airspaces in the route of flight.
I realize not all airspaces (e.g., TFRs) have clear cut, well described, altitude limits but where able or where the flight path crosses well defined airspaces (e.g., Class B, C, D) if should not list those airspaces if the desired flight plan altitude does not penetrate them. Listing ALL airspaces regardless of altitude, diminishes the utility of the feature, as a person can simply look at the chart and see where the flight path passes thru.
