The future pilots of the F-35 will be the first to use a helmet-mounted display system (HMDS) without the aid of a traditional heads-up display. This means all the information that is usually presented on a HUD screen will now be projected onto the pilots visor. All the data needed will follow as a pilot turns his head, meaning he will never have to loose visual contact with the enemy to look at a display. The new visor in use on the JSF 
helmet is much larger than on earlier helmets giving the wearer an unprecedented view of the sky. The helmet will provide for night vision and target acquisition. All the pilot has to do is look at his target to lock on it and begin tracking. He will be able to fire on a bogey anywhere around the plane, even directly behind and let the missile do the work of positioning itself. Using the vast array of sensors on the aircraft, a virtual complete picture is given to the operator, making it seem like he is on the outside of the aircraft without any visual obstruction. If the pilot were to look down for example, he would not see the floor of the plane but rather the ground and potential threats below him. This revolutionary awareness of the battle field coupled with a simplified cockpit and revolutionary airframe will make the F-35 a very easy plane to fly giving the pilots of the JSF the ability to focus solely on their target.
