Recently journalists had chance to visit OKB “Sukhoi” and see and look at the new training simulator designed for training pilots multipurpose fighter Su-35. click to enlarge
The Su-35 is a deep modernization of the Su-27 and belongs to a generation 4 ++. The aircraft is designed for air superiority, as well as to destroy air ground and surface targets. Inside fighter Su-35 is fifth-generation technologies that provide superior fighter in its class. Distinctive differences of the Su-35 to Su-27 are new engines with increased thrust TVC, wide range of aircraft weapons, new avionics based on digital information management system and software, a new set of on-board radio-electronic equipment with a phased array radar and two-stage hydraulic drive, etc… Radar of the Su-35 can detect the type of fighter with the goal of flight efficiency dispersion in three square meters at a distance of about 400 km.
The aircraft has ultra-high maneuverability at low and near-zero rates. This capability is provided through the use of special aerodynamic design and the latest engines with thrust vector control (TVC).
OKB “Sukhoi” plans to make an training complex. It consists of an integrated simulator, procedural and educational computer class flight and engineering technical staff, who are united in a single information and methodological framework that will make all the things complex for training of pilots and engineering staff together.
The class is theoretical training with an automated control knowledge elements and are processed in a procedural simulator and then on the complex, which looks similar to origin cabin of the Su-35 fighter (closing lantern, safety harness, with a spherical dome visualization 270×110 degrees.), and it can practicing almost all kind of processes and problems.
It can be used in network so can connect up to 16 simulators and at the same time perform group training pilots. Over time, it will be possible to combine different types of exercise equipment in one information environs – training -simulator complex. In the future its planned to integrate simulators of other Russian developers.
Integrated simulator purposely is not equipped with mobility system, because the system can simulate only a small part of a large range of highly maneuverable fighter overload, and with mobility will show and display inculcate false skills.
The simulator can perform almost all the same tasks as the pilot is in the plane, including air refueling and the most important thing – testing of emergency situations. This simulator even surpasses the real plane because simulate some troubles and failures situation which are in reality very dangerous, and sometimes impossible. And this is one of the key functions of the simulator.
How does work simulator Workplace of the Su-35 pilot in full flight simulators is a ventilated enclosed cabin type, where there are everything necessary for comfortable combat mission. On desk with monitors, outside the cockpit, is instructor place. The basic controls are: Pilot control stick, engine control levers and pedals.
Information tools are collimator aviation pilot light with a control panel display, which displays flight information, two MFI-35 (multifunction display) every 15 ” control integrated system backup devices, multi-function remote display with a working field 4×5 ” helmet-mounted display system and a voice alarm system. Multi-function board with a working field 4×5 ” is used to configure all aircraft systems, including radar sighting and navigation equipment, weapons, video recording system.
Automatic thrust control and automatic control system, allows, pilot to keep control a desired rate of movement in all maneuvers and in any conditions or fully automatically keep the aircraft on the route in accordance with the flight plan. The must-do of the pilot is reduced only to the take-off and landing tasks, as well as deciding on the use of weapons. How we fly here? First, the instructor make a flight scenario of the exercises with given tactical and meteorological conditions on a real map in a given area. Also, the instructor can quickly enter into a flight or cause failures and faults by monitoring the reactions of the pilot.
Workplace of the instructor is desk with multiple monitors. On the three-dimensional map shows the pivot points, the turning points of the route, and some goals. On another monitor instructor is monitoring the reaction of the pilot, authorities and management and flight parameters. On the third display is general view of the simulator, etc … Any of the buttons, displays, conditions,…instructor have possibility to zoom in virtual on his monitor. In fact, flight is happening by itself. The learner is in the cockpit, and the instructor at his workplace. After the training, there is debriefing. In the photo test pilot OKB “Sukhoi” Sergey Chernyshev performs a test flight and shares his impressions with reporters.
According to Sergei, the philosophy of modern combat mission is as follows: a pilot taking off and waits until the plane automatically to reach a given point; then he decides to use of weapons in accordance with the combat mission (presses the button “defeat the enemy”), waiting until the plane comes back to the base. Thats all. “The list of tasks to be solved and is already doing this plane is huge. It is characterized by an enormous range of altitudes and speeds, impressive range and endurance, a huge range of weapons that can be used at any time and in any weather conditions. And all these possibilities controls only one person! ”

Slow shutter speed values. The more milliseconds shutter is open to let the lens and in camera to collects more light on the cmos sensor the more distorted "movable" parts in the frame gonna look. Aperture and sensor sensitivity (ISO) values plays a big role too..

A simplified explanation would be that the camera sensor doesn't capture the whole image at once. It is called the rolling shutter effect. http://en.m.wikipedia.org/wiki/Rolling_shutter

Correct! All modern dslr cameras fill the matrix of pixels of snapshot from top to bottom, row by row. Usually, 1/4000th of a second is sufficient to prevent this. Otherwise, there is a big change to get something like this:
