In 1983, none other than the legendary Sid Meier created Solo Flight, one of the first, realistic flight simulators, and possibly the first to include a game mode designed to test your skills as a pilot.
There is no autopilot here, no computer-aided navigation. This is old-school dial-based flight instrumentation, which will challenge your skills when bad weather takes away the horizon and prominent landmarks. You will need to rely on VOR navigation — short-wave radio signals from ground-based stations and airports — to guide your plane to its destination.
