    Again, that is assuming P15 ‘as is’ does not have that capability. I’m not quite sure we’ve definitively established it does not have that capability already…. I’m also not even quite sure 11356 and P17 have the same CMS (there has apparently been a change in project cost [see: http://www.bharat-rakshak.com/NAVY/Ships/Future/189-Frigate.html%5D, so perhaps only the last three share that, but again: no firm info). Also, I’m not sure CCIS refers to the CMS or the communications suite.

    P15 Delhi class (Italian derived Indian CMS)

    http://www.bharat-rakshak.com/NAVY/Ships/Active/182-Delhi-Class.html

    P17 Shivalik class (Indian CMS)

    http://www.bharat-rakshak.com/NAVY/Ships/Active/190-Project-17.html

    Project 11356 Talwar class (Russian CMS)

    http://www.bharat-rakshak.com/NAVY/Ships/Active/180-Talwar-Class.html

    As per the article and from what they said, CCIS looks like the CMS, but can it be just for communication…

    Our successful cooperation is well exemplified by the joint development of the radically new combat command information system for project 17 capable of controlling weapons operated by not only a single ship, but by a whole naval force.

    I’m not sure either. But its a combat system not just able to manage own ships combat assets, but also able to control the weapons from other ships and a whole battle group. For instance, not designating AD missiles from different ships to the same target etc.

    The “indigenous” and “locally” developed systems these days does not hold much value because most of it are with JV and ToT and which are locally produced. The Indian developers and manufacturers have started calling everything as “indigenous”, corrupting the meaning that we used to have it earlier.

    In the P-17 link, there isn’t mention of the Russian involvement in the combat suite where as the page from United Ship Building Corp clearly mentions the Joint Development (possibly a modified version of what was available earlier) for the CCIS (what ever it means). That is the reason why I asked who is that “our” meaning the entity involved in the CCIS developeed for P-17.

    Takeoff / Landing at Extremely Low Speeds

    The world’s only amphibian equipped with a BLC (Boundary Layer Control) powered high-lift device, the US-2 can cruise at extremely low speeds (approx. 90 km/h) and take off and land on water within a very short distance.

    http://www.shinmaywa.co.jp/english/guide/image/capability_img05_03.gifhttp://www.shinmaywa.co.jp/english/guide/image/capability_img05_02.gifhttp://www.shinmaywa.co.jp/english/guide/image/capability_img05.gif

    Outstanding Seaworthiness

    ShinMaywa’s original spray suppressor and spray strip realize excellent seaworthiness, thereby preventing damage to airframes when landing on water. Together with its capability to cruise at extremely low speeds, the US-2 can take off and land on water with waves up to three meters high.

    The Be-200 can operate from either a 1,800 m long runway or an area of open water not less than 2,300 m long and 2.5 m deep, with waves of up to 1.3 m high

    No it is way behind in capcity to Shinmaywa at least for amphibious aircraft

    I’ll believe that capability of ShinMaywa US2 to operate during 3m high waves when they post a video of it actually operating. Else it is very difficult to believe. Even in the videos of the aircraft taking off in relatively calm weather with very low waves, the amphibian ride doesn’t looks smooth compared to the Be-200 or A-40.

    But there is one very definite advantage that ShinMaywa US2 have and that is its very short take-off and landing capability on water. Others like range and the promoted 3m capablity (when tke-off with even lower wave height looks shaky) is not at any significant capability for a game changer. If ShinMaywa is selected, it will be mainly for its short take-off in which it wins hands down.

    Also,

    ShinMaywa US2
    Crew: 11 (how they are distributed?)
    Capacity: 20 passengers or 12 stretchers

    Be-200
    Crew: 2 (maybe 2 more handling persons?)
    Capacity: upto 45 persons (Search & rescue variant)

    Be-200 have higher capacity, more than double that of US2, and still weights only the same or even less. A more powerful engine will definetely shorten the current take-off distance provided by the old D-30.

    Search & Rescue
    http://www.beriev.com/images/b200_chs.jpg

    Be-200 search and rescue aircraft can loiter within two-hundred-mile zone for 6.5 hours.
    The aircraft equipment includes inflatable rubber dinghy, thermal-imaging and optical search aids, and first-aid means.
    Be-200 aircraft in this modification can take up to 45 passengers aboard.

    Ambulance

    Be-200 aircraft in ambulance version provides evacuation of up to 40 injured persons on stretchers, with medical staff attending on the injured. The aircraft is equipped with emergency-diagnostics and intensive care facilities. 30 injured persons can be transported on stretchers.

    Transport

    What makes you think the CCIS on the P15 Delhi’s in not compatible, or cannot be made compatible during MLU? Follow on Kolkata class P15A will surely take mny of the same systems as P17.

    It maybe possible in the future though not sure if the current system on Delhi class is compatible. Maybe or maybe not.

    But I was talking about a time 12 months from now and in this time period Delhi class is not going to be upgraded. So the only ships with CCIS will be the 6 Talwar class and possibly 2+1 Shivalik class.

    also cnnot agree with Jangbogo. If sukhoi wants to make commercial jets they should. its Tupolev’s fault for not making anything competitive.

    I think you got me wrong.
    Its completely ok and the way forward if Sukhoi want to make commercial jets. Start the project with own effort and compete with a good product. I don’t criticize that. But the fact is Sukhoi have always managed to oust their opponents due to their political clout and that is what I dislike. Sukhoi did not venture into the commercial space due to their own effort. I don’t think anyone will ever say that Sukhoi could have ventured into the commercial space on their own. There was state finance and support involved and they managed to leach it completely at the most crucial time and starved all others of support and funds.
    I’m not saying Sukhoi do not have the capability, but the way they do it I don’t like.

    Superjet 100 Crash Probe May Take More than One Year
    06:30 11/05/2012
    JAKARTA, May 11 (RIA Novosti)

    It may take experts up to 15 months to investigate the crash of a Russian-made Sukhoi Superjet 100 aircraft in Indonesia, a representative of the Indonesian transport security committee said on Friday.

    The probe is unlikely to be completed promptly because of “complex conditions” in the area where the aircraft crashed, he said.

    The plane slammed into a steep mountainside at Mount Salak, outside the capital Jakarta, during a demonstration flight on Wednesday. There were 45 people on board, including eight Russians, one American, one French, two Italians and 33 Indonesians.

    On Friday morning, a search operation continued in the area of the crash. The nearly vertical face of Mount Sakal has made search efforts extremely difficult.

    The searchers have so far discovered no sign of any crash survivors. Rescue teams in helicopters have so far only found parts of the aircraft’s tail, local media reported on Friday. The aircraft’s flight data recorders have yet to be found.

    At 9 a.m. local time (02:00 GMT), an advance team of 10 Indonesian searchers was 600 meters away from the crash site, the Detik.com online news portal said. The team has been trying to clear a site for helicopter landing, the report said, quoting a spokesman for Indonesia’s rescue service.

    Six helicopters have been sent to the area. One of them is carrying Leonid Kashirsky, an official from the Interstate Aviation Committee, the Moscow-based body that carries out crash investigations in the CIS .

    Russia’s acting Deputy Prime Minister Dmitry Rogozin said on Thursday experts believe the “human factor” was the most probable cause of the fatal crash. He maintained the aircraft is competitive and has “a bright future,” despite the tragic crash.

    The Sukhoi Superjet-100 is Russia’s first new passenger jet since the fall of the Soviet Union and is designed to replace the obsolete Tu-134 and Yak-42.

    Kartika Airlines puts 30 Superjets on hold
    Published: 10 May, 2012, 20:10

    An Indonesian air carrier has delayed the delivery of 30 Russian Sukhoi Superjet 100 aircraft following Wednesday’s plane crash, according to Indonesian media reports.

    Arifin Seman, the commissioner of Kartika Airlines, said the Jakarta-based carrier would wait until Russian aircraft maker Sukhoi investigates the cause of the incident.

    However Sukhoi Civil Aircraft, which produced and developed the Superjet-100, says it has not received any official notification from the carrier, a source in the Russian air company told news agency Itar-Tass.

    Fitch Ratings agency expects the crash of the Sukhoi Superjet 100 to negatively affect orders for the aircraft in the short term, but not the ‘BB’/Stable rating of Sukhoi Civil Aircraft, the plane’s manufacturer.

    “It’s not good news of course, we don’t know the cause of the crash yet. But the real problem with the legacy of Russian aviation is in the engineering or the quality of the product. It’s the image of safety. The quicker they can clear up this issue, hopefully proving that it has nothing to do with the aircraft itself, the better off they’ll be. Right now they are suffering under the overhang of that perception of safety problems and this is a very unfortunate event”, says Richard Aboulafia from Teal Group Corporation.

    Though a crash is always a blow to an air company’s reputation, aviation market experts agree this is unlikely to seriously affect Sukhoi’s business.

    “I do not think the crash will lead to a decrease in sales as long as the accident becomes known very quickly, and the company are very open and transparent with the results of what went wrong. If it is not a failure of the airplane, but something that happened due to pilots or weather etc, this will make it a non-issue. If it’s a structural deficiency they have to be open and tell the truth to potential clients, including what they will do to make sure it is fixed and will never happen again”, says Stan Wraight, Managing Partner at Strategic Aviation Solutions.

    Three officials of Kartika Airlines, including the company’s operational chief were on board when the plane went missing near Mount Salak in West Java at 2:33 pm local time on Wednesday. A rescue helicopter finally discovered the missing plane at 9:15 the next morning on a slope of Mount Salak in Bogor, West Java, at a height of 5,500 feet above sea level.

    Kartika Airlines, which became the first company in Southeast Asia to purchase the new Superjet 100, had agreed to order 30 planes in a $951 million deal in 2010.

    The first delivery was scheduled for September this year. Kartika Airlines, Sky Aviation and Queen Air are among dozens of airlines to have emerged in Indonesia in the last decade to satisfy the growing demand for cheap air travel, having ordered a total of at least 48 Sukhoi planes.

    According to Sukhoi company, they secured around 170 orders in total as a more attractive price and lower operating costs are giving Russian aircraft a competitive advantage over Brazil’s Embraer and Canada’s Bombardier. Indonesia, the world’s fourth most populous nation with a fast-growing middle class, is already one of the biggest customers.

    The Superjet project is a joint venture between Sukhoi and Italy’s Alenia Aeronautica, part of the aerospace and defense giant Finmeccanica. The producers of the jet aim to sell 800 planes by 2029 and take 15% of the global jet market.

    There are only 8 Superjets in service worldwide so far – most of them used by Russia’s Aeroflot, which tweeted it will not stop using Sukhoi Superjet 100 commercial jetliners. “All the SSJ100 planes are examined daily and perform flights on schedule,” the airline’s Twitter said.

    At Least 10 Bodies Found at Superjet Crash Site
    11:31 11/05/2012
    JAKARTA, May 11 (RIA Novosti)

    The bodies of ten to fourteen people have been found by rescue teams in the wreckage of the Sukoi Superjet 100 airliner which crashed near Jakarta, Indonesia, on Wednesday, killing all 45 people on board, the director of the Indonesian emergency ministry’s crisis center said on Friday.

    The aircraft hit steep ground at an altitude of 5,200 feet (1,600 meters) on Mount Salak near Jakarta during a demonstration flight. Eight of those on board were Russian, including the flight crew.

    Indonesian rescue teams finally reached the crash site on Friday by roping down from helicopters. Further search teams are heading for the scene on the ground, hoping to clear landing sites for helicopters in order to bring out the bodies of the dead and wreckage.

    Meanwhile, simulator trials held at a flight research center near Moscow suggest pilot error was a likely factor in the accident, Izvestia daily reported on Friday.

    The trials, held at a pilot training center at Zhukovsky near Moscow, simulated “various emergency situations and concluded that none of those could have been behind the crash,” the paper said.

    The SSJ-100’s cockpit terrain warning system informs pilots of approaching obstacles, a source at the center said.

    “You just cannot miss the alert signal: if there is a danger, the system puts an alert message onto the central display, and a red light indicator as well as a speech alert come on,” he said. “Besides, automatic systems can intervene to try to help the plane avoid a colllision.”

    The source suggested the pilots may have turned off the alert system in order to speak with the passengers or show them around the cabin.

    Another expert at the center said the pilots may have “stopped taking notice” of the alert system as it is “nearly always on” in mountainious regions.

    On Thurdsay, Russia’s acting Deputy Prime Minister Dmitry Rogozin said experts believe “human factor” was the most probable cause of the fatal crash of the aircraft.

    “Experts say that all [the aircraft’s] equipment functioned smoothly. In other words, it could be some kind of a human error,” Rogozin told journalists.

    ^^^
    that was to be expected. The earlier the investigation is over, the better.
    But will the airlines who had earlier planned to buy the jet, still buy it??

    If the airlines don’t consider the unfortunate event as a bad omen, then probably they will go ahead with the contract after the investigation is over and the findings are on the positive side. Elze, its going to be bad for Sukhoi who started off their selfish individual project in building commercial brand name by almost destroying other players like Ilyushin, Tupolev and Yakovlev.

    Another question…

    The aircraft definitely would have had a Terrain Avoidance Warning System. So the question is how much seconds/time will it take the TAWS to respond/activate the warning?

    You mean 6.2km a minute ?

    yup, sorry… anyway WL747 have corrected it below.

    I would suggest you look at your maths.

    200kt = 220mph = 354km/h

    3600 secs in an hour therefore 354/3600 =0.098

    in a second at 200kt, it would have travelled 98m.

    Being too low in patchy rainclouds within a mountainous area usually ends badly, regardless of reaction time.

    Kind Regards,
    Scotty

    Yeah, somehow i missed that vital 60 seconds during conversion.
    I took 1.86 to arrive at 6.2km/h. But if we take 1.852, then it is 370.4km/h or 6.172km/min. Which gives 102.888m/sec

    Anyway if we take 98m/sec it would have given just around 17 seconds as reaction time to pull out. 😮

    The above is based on 200kts. So one more question, what would have been the real or normal flight speed for a commercial airliner of that class at that altitude?
