In the past, I have been checking various individual sources before a flight. Sector maps, Local METARS and NOTAMS, KP Index etc most from different sources. Out of curiosity, I'm guessing that there are some apps out there that will check most of these items all at the same time or at least all from within one app. Maybe even something that would let me keep an extra note or two as part of a flight log or maintenance logs. I have seen a few apps out there, but some are just junk and not very complete. May I ask what the rest of you are using or doing to check an area before your flights?
