B777 Ldg Climb Limit Weight Table
The B777-300 Landing Climb Limit Weight table says one must decrease the weight by 1500kgs if eng and wing anti-ice on.
Then it says"When operating in icing conditions during any part of the flight with forecast landing temperature below 10 C , decrease weight by 19150kgs"
Why the difference? I thought the 1500kgs would allow for the wing and anti ice on? Whats the the story with the 10 c things and then such a big penalty?
