Hongdu L-15
HAIG unveiled a full-scale mock-up of its L-15 advanced lead-in trainer (LIFT) in the 2004 Zhuhai Airshow. The two-seat, two-engine L-15 features the latest advanced technologies developed by China, such as digital quadruple fly-by-wire (FBW), glass cockpit (two multi-color head down displays for both the front and rear cockpit, and an additional head-up display for the front cockpit), and hands-on-throttle-and-stick (HOTAS) flight control. The look-down field of view for the frontal cockpit is 18 |

L-15 ni design dia sejibik macam Yak130 and M346 kan!!! Both Yak & Machi tak keluar lagi dalam product line tapi depa punya dah siap offer kat 3rd world airforce dah. Walhal berapa lama Yak & Machi dok usaha keluarkan model ni. Hebat PRC ni... |

dari segi tooling, China is better than Russian. Sbb tu J-11 buatannya lagi bagus dari Su-27. Tapi, dari segi design dan reliability, sendiri beli sendiri tanggungla.
but, it is a matter of time China to catch up with the west. |

J-11
The Chinese-built, Chinese variant of the Su-27SK with 70% components made in China, with some improvements over the original Su-27SK in the following areas: radar, flight instrumentation and added air-to-surface attack capability.
Radar:
= the original N001 radar on Su-27SK purchased by China in the 1990s is replaced by its successor, N001V, which like N001, can also simultaneously track 10 targets.
= However, when engaging a target out of the 10 tracked, the original N001 radar would lose all of the rest 9 targets tracked, and must restart a new tracking process after the engagement.
= N001V radar on J-11 overcomes this shortcoming so that during the engagement, the rest 9 targets tracked would not be lost. The major internal structural difference between the two radars is that the original TS100 processor in the older N001 radar is replaced by a more capable TS101M processor in the newer N001V radar.
Flight instrumentation:
= in comparison to Su-27SK with only one small CRT multifunction display (MFD), J-11 has a total of two by adding an additional one directly atop of the original small CRT MFD at the top right corner of the flight instrumentation dashboard. This new small CRT MFD is about the same size as the original one on Su-27SK, and it is located to the right of HUD.
= Additional air-to-surface attack capability: The additional MFD is mainly used to control the electro-optically guided precision munitions such as TV guided or ImIR guided missiles in attacking ground and sea targets, since the domestic Chinese electro-optical pods and electro-optical guided precision munitions are extremely difficult to be directly integrated into the Su-27SK.
=The images and information for the electrical-optically guided munitions, as well as those provided by the domestic Chinese electro-optical pods can not be displayed on the original CRT MFD of Su-27SK, and they can only be displayed on the additional CRT MFD added. Despite this added air-to-surface attack capability, it must be noted, however, J-11 still lacks the full air-to-surface attack capability of later models because due to the limitation of the radar, the radar guided air-to-surface missiles can not be deployed. |

J-11A
J-11 with further radar and flight instrumentation upgrade, most notably with the adoption of EFIS in its avionics.
Radar:
=The N001V radar on J-11 is replaced by its successor, N001VE, which has the same tracking capability like its predecessor. The radar improvement is that in comparison to the older N001V radar which is only capable of single target engagement, N001VE is capable of simultaneously engaging two of the ten targets tracked with semi-active radar homing air-to-air missiles.
= The major internal structural difference between the two radars is that the original TS101M processor in the older N001V radar is replaced by a more capable BCVM-486-6 processor of the Baguet series processor in the newer N001VE radar.
HMS:
=A more capable domestic Chinese helmet mounted sights (HMS) first begun to appear on J-11A, which soon became standard all version of J-11, including retrofitting earlier J-11.
EFIS:
=Most of the analogue dial indicators of the original Su-27SK are eliminated, replaced by four color MFDs, which are part of the overall EFIS system designed by China Aviation Industry Corporation I. There are three large MFDs that take most of the space of the flight instrumentation dashboard, with the MFD in the center is in a slightly lower position than the other two on the sides.
=A slightly smaller color MFD is located below the three MFDs, to the bottom right corner of the flight instrumentation dashboard. Since all of the official photos of the EFIS by China Aviation Industry Corporation I on J-11A released by the Chinese governmental authorities so far are full frontal views, it is difficult to confirm if these color MFDs are either CRT, or LCD as claimed by many domestic Chinese sources. |

J-11B
This is the 4.5-generation multirole version which uses more Chinese components, including radar, engine, and missiles. The chief program engineer for J-11B is Mr. Guo Dianman..China is interested in reducing its reliance on foreign technology for both cost reasons and a desire to improve its domestic research and design.
It is reported that one regiment of J-11Bs are currently in service, but this seems to contradict with the latest information provided by the Chinese government: In May, 2007, the existence of J-11B was finally acknowledged by the Chinese government for the first time when the state-run Chinese TV stations first aired the report on J-11B in PLAAF service.
However, the official Chinese report claims that there are only two squadrons of J-11Bs in service, instead of a regiment, which is consisted of three squadrons (as of end of 2007).
According to the Chinese report, which is agreed by some western sources such as Jane's Information Group, the J-11B is superior to Su-27SK in the following areas:
A. The wide adoption of composite material (mainly carbon fiber) for the surfaces, reducing the weight of the aircraft for more than 700 kg, while the life of the composite part is increased over 10,000 hours in comparison to the original part built from steel.
B. Redesigned air inlets of engine intakes to reduce the radar cross section, this coupled with the adoption of composite material, and application of radar absorbent material has reduced the radar cross section (RCS) of 15 square meters of Su-27SK to just >3 square meters of J-11B.
C. Full air-to-surface / sea capability is added and J-11B is able to launch various precision guided air-to-surface and air-to-sea munitions.
D. Certified to be equipped with WS-10 (will be upgraded to WS-10A in the future) turbofan engine, which is claimed to be cheaper to operate than AL-31F.
E. Incorporation of on-board oxygen generating system (OBOGS): With the exception of Su-35 and Su-37, J-11B is the first of the Su-27 family to incorporate such technology. Due to the adoption of western style design features such as fully digitized computerized controls and solid state micro-electronics, Chinese claimed that the domestic OBOGS is superior than the analog system Russia offered to China.
F. Improved radar
= The new radar is able to track 6-8 targets at the same time, and engage 4 of the 6-8 tracked simultaneously. When used against large surface target such as a destroyer, the maximum range of the radar was in excess of 350 km. The range against aerial targets was not disclosed, but it would be definitely much shorter, as in all radars.
=The Chinese official report claims that the radar is better than the 147x/KLJ-X radar family, but stop short of identifying the exact type. Contrary to many erroneous comments by many domestic Chinese sources, which mistakenly claimed that the radar had adopted a passive phased array antenna, the official claims of many Chinese governmental sources such as technical journals and publications have revealed that the radar still adopted a slotted planar array antenna.
=Fully digitized solid-state avionics has replaced the analogue one in Su-27SK. In the mid-2007, the Chinese governmental television station CCTV-7 released news clips of Chinese pilots in the cockpits of J-11B, with the LCD of glass cockpit of J-11B clearly visible, despite that the official report itself only claimed replacing the original avionics with domestic Chinese fully digitized solid-state avionics, and nothing of EFIS or glass cockpit was mentioned.
=In comparison to the earlier EFIS on J-11A, the most obvious difference is that LCD MFDs on J-11B are aligned in a straight line, instead of the middle one being slightly lower. The arrangement, appearance and layout of MFDs and EFIS of J-11B are similar to the general design concept of the west.
