Both the 1-11-200 and -500 exist as regional airliners in Aeronautica; unfortunately, in this niche, the majority of their competition can carry more passengers across a greater range, with a cheaper initial purchase price.
My suggestion would change the range of the 1-11s. Most information about the type I could find online suggests a base 720nm range for the 1-11-200, and an ~1480nm range for the upgraded 1-11-500; this is clearly too high for the scale and purposes of the game.
Instead, I propose the 1-11-200 receive the 500's 91nm range, while the 500 receives a range buff to 108nm, enabling both to exist at the upper-end of the short-range regional jet market in the game. This would also serve as a minor incentive for newer players to choose these types over the CRJs and ERJ/E-Jet families.
