I know this isn't a cockpit build post, but I wanted to share a great app I ran across for the iPhone/iPad to display what looks to be world-wide coverage of sids/stars charts, ILS/GPS approach plates, airport & parking diagrams, hot spots, take-off mins, etc, etc, and basically just about any chart you'd need in this handy little app! I love it. It sure beats looking up charts on Airnav or FAA websites!! Just do app store search for "circle to land"
