Currently the NOTAM display does not display any indication as to whether NOTAMS were checked for destination and alternate airports if those airports have no NOTAMS. The AIS/NATS NOTAM brief displays NIL under the airport if no NOTAMS are found. Without an indication that the destination or alternate airport has no NOTAMS it is difficult to assess whether you are getting the output you expect.

I'd propose updating the NOTAM output to indicate, as per the AIS/NATS output, the destination airport and alternate(s) with NIL displayed below them where there are no NOTAMS. This way we can be sure the NOTAMS have been successfully checked.
