In Flightfrom Addendum to 3-D Helicopter Simulator documentation, version 1.0, 8/28/87.
AutorotationPage 21, last paragraph. Failure of your engine during flight will always result in your "death"
AH-64We have included a loadable helicopter modeled on the Apache AH-64 military attack helicopter. Although this will change your appearance, your helicopter will still fly as though it is a Robinson R-22.
The Edge of the WorldWhen you fly off the "edge" of a scene, you will "wrap around" to the opposing side. For instance, if you fly East from town long enough you will eventually re-enter the same town from the West.
Controlling the HelicopterWe have attempted to accurately simulate the controls of a real helicopter by slightly delaying the keyboard response to match the delayed response of real helicopter controls. This produces an "inertia" effect which is a prevalent helicopter flight characteristic.
JoysticksPage 31 of the documentation mentions that dual joysticks are required. If only one joystick is used, it will be presumed to be the cyclic stick.
Scott "Zuma" Wolffor the scan. continues:
The 3-view illustration on the manual cover shows a Hughes 500, which I believe is also the helo you're "in" on the box cover, Apache notwithstanding. From shots on the back of the box it looks more like an old Bell 47G with a covered boom. "
