787 tankering question
Can't find any guidelines / links for 787 tankering.
Anyone have this (or emprical knowledge) of how much landing fuel would give adequate ullage space bettween fuel and top skin. Have heard 15 to 20 tonnes mentioned (no supporting ref. this may just be someone suggesting half tanks)?
Previous company left it to pilot's discretion but suggested taking destination Non Environmental Icing into consideration at temps below 15 degrees with high humidity.
Also heard some companies ban tankering in contaminated conditions.
