  chuck yeager's air combat, often shortened as cyac, is a 1991 combat flight simulator video game by electronic arts. famed pilot chuck yeager was a technical consultant in the game and his digitized voice is featured in the game, giving encouragement and praise before and after missions. the game is characterized for its good balance of an action laden gameplay which focuses on classical dog fights and a simple but still realistic flight model. the game was initially available for dos, and later ported to the apple macintosh. the latter version is considered superior as its graphical display is at a much higher resolution, multi-player network play is supported, and saved movies may be exported in quicktime format. ==gameplay== the game featured six player-flyable aircraft: p-51d mustang, f-86e sabre, f-4e phantom ii, fw.190a-8, the soviet mig-15 'fagot' and mig-21mf 'fishbed'. other featured ai-driven aircraft were: me.109e, me.110b, me-163b komet, me-262 schwalbe, p-47d thunderbolt, yak-9, mig-17mf 'fresco' and f-105d thunderchief as opposing fighters and b-17e, b-29c, b-52 and l-5 as aircraft to either protect or shoot down, depending on the mission. unlike many other flight simulation games of its day, altitude and aircraft characteristics have a big influence on the behaviour of the game's simulated aircraft. many missions take place at the limits of the aircraft's performance, challenging the player to keep the plane within its flight envelope. for instance, the opening historical mission as a luftwaffe pilot pits their fw 190 against the group of unescorted b-17s, but at an altitude that makes even basic flying difficult. realism has been sacrificed to some degree to enhance gameplay, however, e.g., a real fighter plane expends all of its ammunition after a few short bursts, while in chuck yeager's air combat the rate of fire has been reduced considerably, making dog fights longer. to assist a newcomer to the game several help features can be activated, such as unlimited ammunition or easier aiming. a virtual chuck yeager can be activated, who gives advice. because of the limited graphics capabilities of software and hardware of the time, the
