   T-50 cockpit.

It should be noted that the release of the T-50 cockpit map is not the first exposure of the T-50 cockpit.As early as 2010, when Russia first released its T-50 fighter plane, it had already released pictures of the cockpit. 


Russian media exposed the cockpit picture of T-50 as early as 2010.

Look at the photos from the current exposure,T-50 uses cockpit display control systems that are almost identical to Su -35S.
The display system in the cockpit consists of two large color multi-function LCD displays, a wide-angle diffraction head up display and at least 3 small liquid crystal displays.Two 15 inch large multi-function displayA series of fighter Su 30 legacy

The main display fire control radar, electronic countermeasures and other information. 3 small liquid crystal display, a display is installed in the bottom of the head up display, mainly display important targeting and navigation data, and HUD set parameters; second small display analog display indicator; third at the lower right. It is not clear from the screen that it has a small display on the left knee similar to the Su -35S. Maybe just put this small monitor of sue -35S to the right.


The details of the T-50 display control system are shown above


This graph is Su -35 cockpit map, although the use of almost the same display and control equipment with T-50, but gorgeous lights make it seem full of technological sense.

At present, Russia has not yet released T-50 display specific information, but can be announced by Russia's su -35S display control system information to determine the general performance of T-50 monitors. 

15 inch MFI-35 multi function display two multi function displays and Su -35S are very similar, which can display 5 dimension picture, can automatically adjust the brightness and contrast, and includes 40 peripheral function keys and 2 used to manually adjust the brightness and input parameters with the knob, the overall weight of 12 kg

The display can display charts, TV images, or double display, as well as split pictures. It should be noted that the monitor is a universal display and is also used for the -52 helicopter gunships. From this point of view, the T-50 uses the monitor and is likely to be a transitional product. T-50 may be using this product because of lack of money.For such a Russian military only tens of billions of dollars in military projects.

The control panel of a suspected MFPI-35 multi-purpose control panel display right, is one of the main interface system pilot and machine, the display \/ control panel will past the dashboard complex operation function integration. On the Su -35 fighter cockpit, this panel \/ display system is located below the left. T-50 is on the right side, it may be for the right hand manipulation is more agile and skilled, then you can make the left hand to operate the throttle, or the left side of the display control panel is installed on the other.

 

The cockpit shown in Figure two is F-22A, and the F-22 display and control system uses 1 head up displays and 6 lower view displays, with a total resolution of 1 million 350 thousand pixels and an area of 201 square inches.

At least from the outside point of view, the T-50 monitor is better than F-22's.. The F-22 display and control system uses 1 head up displays and 6 lower view displays. The wide-angle full view head display has a field of view of 20 degrees and 30 degrees. 

The 6 condition is divided into 3 categories: 1 to 8 inches (20 cm to 20 cm) and multi function display, 3 to 6 inches (15.2 cm to 15.2 cm) auxiliary multi-function display, 2 to 34 inches (7.6 cm to 10.2 cm) above the display, each color display for the 5 gray level, all the active liquid crystal display, the total resolution of 1 million 350 thousand pixels, show a total area of 201 square inches. The final 8 inch display instead of the original 10 inch monitor was mainly restricted by the technology of the military cockpit display.

Rafale. The demonstration and control system of the gust fighter is simple and fluent, and the man-machine engineering is fully considered.

Europe's four generation semi fighter, such as "typhoon" and "gust" of the display control system, roughly the same as F-22 or worse. From the above point of view, the whole set of T-50 display and control system in the display area, integration and other basic indicators, even higher than F-22 and Europe's four generation semi fighter, such as "typhoon" and "gust."". But it does look a little more earthen. One important reason may lie in the fineness of workmanship and materials, and the color of the instrument panel. Russian fighter planes traditionally use light blue panels that do not look so tall, but some analysts believe that the color helps lower the pressure of the pilot.

There is a gap with the top cockpit
Of course, F-22 and the European "double wind" is not representative of today's display technology to the forefront of the level of T-50 and F-35, if America using explicit control technology than it is not just looking at "soil", but also in technology has indeed been behind us the most advanced cockpit.


F-35's cockpit represents the world's most advanced levels, and its cockpit design has been evaluated by over 1300 pilots and experts in ergonomics.

In the cockpit of F-35, a variety of dashboard and indicator completely disappeared, replaced by a large color digital touch type lcd.

This is a 8 inch, 20 inch (20 cm, 50 cm) single screen full-color multi-function display, resolution of up to 1200X3200, easier to fuse radar, electronic warfare, photoelectric detectors and other systems information. 

The pilot only needs to touch the corresponding area on the multi-function display with his finger, so he can adjust the display and display sequence of various information at will, and restart the display system. Moreover, the left and right display area work does not affect each other and backup each other. F-35 also uses a helmet mounted display system with a speech recognition and control system that eliminates the previous controller for communications, navigation, and identification.Its cockpit design has been evaluated by ergonomics of over 1300 pilots and experts.

 

Cockpit F-35.

Compare with this set of display and control system,T-50 gap is probably the difference between traditional large screen mobile phones and smart touch phones.The reason why modern fighters pursue larger display area, not to make it look "tall", "extravagant", but for the sake of ergonomics consideration. The cockpit is a human-computer interaction system complex, information intensive, information processing pilots face increasingly stringent requirements, often requires a large amount of information in a short period of time and rapid response decision-making, and prone to high mental workload, even the overload situation. 

In order to improve the ability to withstand overload, the seat is often backward mounted, and then tilt to make the visual range larger, in the same resolution, the required display characters must be increased accordingly. The wide field of view enables pilots to perform flight operations, low altitude penetration and accurate ground attack at night or under severe weather conditions. Studies show that the speed of understanding on a large display is much faster than on a small display. Tests in Europe and the United States show that pilots use "big images" to increase their situational awareness by 100% compared to 2 or 3 conventional small multi-function displays

Situational awareness plays a decisive role in air combat outcome. To some extent, the essence of air combat is to use superior situational awareness to reach the vantage point, destroy the enemy aircraft and evacuate safely". Air combat is regarded as a competitive or combat advantage to gain situational awareness. The total area of T-50 displays is probably not much less than that of F-35, but its distribution is dispersed and human friendliness is poor.


There are still many ping-pong switches left in the cockpit of T-50.

The second point difference in the cockpit display control system of T-50 lies in the poor integration, and uses a lot of table tennis switches, knobs and so on. 

The five generation machine high overload duration and the rate of change has increased, the seat usually tilt back design, to improve the ability of overload, the pilot may move backward, the knee was partially blocked by sight, making the best visual dashboard area move, visible area. In addition, the fighters reduce the cockpit space for stealth, thus reducing the area of the display panel. Therefore, it is necessary to make the best use of the display and control system to reduce the use of switches and traditional instruments. 
In contrast, there are many switches around T-50's display, and more scattered.

 
 

The details of the cockpit display system of F-35 are exquisite.

In addition, from the point of view of the display system control technology, the latest display control system in the United States completely uses the touch control system, in general, to be ahead of the peripheral keys and knobs used by T-50.

The use of the middle of the driving rod helpless.
Another area of criticism in the cockpit of T-50 has been that it still uses the center of the joystick and does not use the side bar technique. From the fourth generation fighter, the use of a large number of west side rod manipulation techniques, and to the four generation and the four generation semi machine is almost uniform side of the control rod, including the aviation industry on display at the Zhuhai air show the concept of advanced fighter cockpit, the driving rod side.


Similar to the T-50, Su -35 also uses a mid drive pole, which is beneficial to Russian pilots' reloading training.

Putting the joystick on the right, plus the arm rest, is more conducive to holding and handling the right hand for a long time. 
In addition, the side driving rod is more favorable for adopting a seat with a larger tilt angle, and the seat is more favorable for improving the overload resistance of the pilot. 
Before against a reason for this is that if the right hand was injured, unable to fly back, while using a stick, the left hand can be substituted for the operation. However, the superiority of the lateral pole in this extreme situation is obviously too narrow. Therefore, the new generation of fighters in the world are using side drive technology.

Data show that Russia has also experimented with side bar manipulation, technically speaking, it is not difficult to achieve side lever control. Russia's eventual absence of side - lever manipulation is likely to be a conceptual difference, and analysts say it may be a pilot's choice". 
But it's important to point out that sometimes the habits of pilots tend to repel newer technologies. For example, head up display technology, pilots who have not used this kind of display, just started the operation will be some discomfort, tend to be some rejection. Therefore, in the design of aircraft, we should obey the pilots' opinions, but they will not adopt all of them.

Russia did not use side bar technology for the T-50, a possible reason for the formation of combat effectiveness as soon as possible. Russia has never had a side - pole aircraft service before, and from the trainer to Su -35, it is a mid - drive.It's probably not possible to develop a two seater T-50 for facelift training.Thus, if the side bar technology is used, it will cause great trouble to the T-50 reloading. The use of traditional mid joystick allows the Su -35 pilots to quickly switch to T-50 pilots, or use the two seat Su -30MK to teach.

Of course, the lever of T-50 were also investigated by man-machine engineering optimization, it adopts non-contact button design small stroke, without the need for circuit board like keyboard that need contact button below, the operation is more ergonomic, and the joystick to tilt slightly to the right, the right hand.


Advanced fighter cockpit in China Aviation industry. Not afraid, afraid of goods than goods. Although the use of large-scale block display, but compared with the F-35, the space utilization is not enough, not tight enough, the production is not refined enough, many aspects need to be optimized. Of course, this might just be a functional prototype.
