Aviation Abbreviations

Besides three letter airport codes which would take forever to learn, there are three letter/number aircraft abbreviations. Here are some of the most common, which I will constantly refer to.

General Rules:

ER- Extended Range

LR- Long Range

For planes not marked with an ER at the end, sometimes they do have an ER variant, but there is no common acronym, and the model plus ER is used instead of a letter (777-300 ER vs 77W. They're the same thing.)
