Some (if not all) planes with winglets in S1 do not fly to the extent of the winglet range.  For example, the A340-300 has a normal range of over 8000 miles but with winglets it says over 9000 miles.  However, when I try to put the aircraft on a 9000 mile route, it does not let me fly with full payload.  I have a feeling that this is only for A330/340 series but could you please explain/fix this?

The state/province name is wrong for almost all japanese airports.  Kanto is not a state, rather a region comprised of many prefectures.  Kyushu, Shikoku, and Honshu are island names, not prefecture/state names.  For example, HND is in the Tokyo prefecture, while NRT is in the Chiba prefecture.  Okinawa and Hokkaido are fine, as they are actual prefecture names.

It says here that the A350-1000 has a max capacity of 440, not 450.

In the last one or two years, Tokyo Haneda (HND) made the C runway (34R-16L) longer to 11,024 ft.  Could You please fix the length? Thank you.

The longest runway at Osaka Kansai (KIX) is the same length  as the longest runway at Tokyo Narita (NRT).  This is based on research and a visit to KIX itself.
