What are A332RR and A333RR?


Actually, in my YouTube channel comment, there was a comment “A333RR, but isn’t it A333ER?” I ask you to get the right answer for that person. What is the difference between ER and RR? And please cooperate with me who wants to convince him.

RR = Rolls Royce which is an engine option

Thank you(^^)

RR stands for Rolls Royce
ER stands for extended range

A friend of mine seemed to know about ER and asked RR, “Isn’t it mistaken for ER?” However, when I heard from the official that it was an abbreviation for Rolls-Royce, I was convinced. The friend was surprised and convinced.
