1992 - Argonaut / MicroProse
In this hybrid strategy/simulator game, you can control one of two vehicles - an F-22 Raptor, or an AH-64 Apache helicopter.
I think because of limiting processing and graphics back in the day, the early flight simulators, like Gunship, tried to be realistic, but were actually easy to play and FUN to play. Now there are two genres - true flight simulators that are so difficult to master, and cheezy arcade flight games that turn things into a turkey shoot. That's why it may be difficult to re-do the magic of the early classic flight sims.
