The speed brake lever may be auto deployed in some aircraft, this effect. Airframe vibrations and drag noises coming from the extended gear. Airframe vibrations and drag noises coming from the extended speed brakes. Adds orientation change head compensation, bring the head of the pilot to life. Hear the pilot breathing heavily and feel the stress on the body. G-force is pulling the ribs down, which empties the air from the lungs. Using this effect you'll experience cockpit vibrations and shakings. Flying in VR is awesome right? Yet, the cockpit is way too static and that reduces the realism. Clear Air Turbulence (CAT) is defined as sudden severe turbulence occurring in cloudless regions that causes violent buffeting of aircraft. This effect costs 1-2 fps! Depending on temperature, altitude, and wind, you might feel ground surface turbulence when flying in low level altitudes. Even when we sit still, our body is moving slightly, this effect will bring these tiny body movements into your cockpit.
During engine start-up, torque may cause airframe vibrations and sounds. Feel the power of the engine when accelerating and when RPM is steady. Your front gear may touch the ground after your main gear to feel a bouncing. Feel how good your landing is! Adds the sound and movements of your touchdown moment. Adding movements to the pilot's body caused by constantly changing ground forces. Adding movements to the pilot's body caused by constantly changing G forces. Turn off the engine and open the door to hear airport ambiance better. Add realistic airport sounds, to bring life into the airport. Random sounds coming from someone sitting in the cockpit. Open a door or get out of the aircraft to hear it! Adds wind when the aircraft is at the airport on a windy day. The faster you go, the more wind you'll hear hitting your windshield. When applying abrupt control movements, the airframe airflow changes and you can hear it. Adds the realistic sound of raindrops hitting the windshield. Did you land in the harbor? Great! Open the door and enjoy the relaxing sound of the ocean. When taking off or landing with floats, feel the splash of the water as you build up speed During the ground effect, the aircraft engine noise is reflected back by the runway surface. On some aircraft, when brakes are applied, a slight squeaking sound may occur. Takeoffs and landings on grass strips might get bumpy, hear the airframe shaking. Add realistic taxi and runway rolling sounds to add to your real experience. Depending on your flight characteristics, a blade slapping effect may occur. Feel the helicopter blades cutting through the air. Feel the power of your engines during reverse thrust. When overspeeding Vne, never exceed speed, aircraft vibrations may appear and airframe may be damaged. When overspeeding Vfe, maximum flaps extended speed, aircraft vibrations may appear, and airframe may be damaged. Once in a while you'll sneeze, let's hope it won't happen during a landing flare. Feel the drag caused by the extended flaps. Unless you'll hit the brakes after takeoff, nose wheel spinning sound will fill the cockpit. Feel and hear the shaking caused by turbulence hitting the aircraft. Adding a more realistic sound to the flaps lever.
XP Realistic Pro adds another level of realism into X-Plane 11!
