Try a copy of PJ.Swatton's book "aircraft performance theory for pilots(2000)'.
It covers the Performance Area quite well(JAA rules)but is pretty well aligned with the FAR's(US)now..
'Flying the wing' doesn't cover the 'wet' ops as well as the JAA rules(reduced V1/lower screen height)as the FAR's only cover 'new' equipement(B777),or
Performance 'B'(JAA rules)customers..Canadair have Certified to the JAA rules.
cheers
