From Sierra Entertainment:
The program allows beginners to become familiar with aviation procedures, flight maneuvers, cross-country flight planning and Air Traffic Control (ATC) communications. In addition to the 3D video graphic acceleration upgrade, the simulator provides support for flight under adverse weather conditions and high fidelity instrument gauges to make Pro Pilot '99 a better instrument simulation. Pilot 99 features all-new 3D accelerated graphics, a new pop-up Operator's Handbook, tutorial assistance for pilots at any skill level and a new trainer aircraft, the Cessna 172R. Now you can fly throughout Western Europe.
