Quick reference handbook: EASA performance
 

Good afteernoon folks,

I am keen to find one (or two?) QRH that can improve my knowledge in Performances i.e. Class A & B in the EASA world. A colleague of mine hqs referred a Scandinavian book that is no longer updated though. Ideally, the book would be including visual items & meaningful explanations. I still have the big books aside so this QRH would be complementary, bringing another point of view.

Any recommendation in other subjects (Principles of flight, Meteo, Air Law≈Doc8168) ?
