    TCAS on mh370

    I have heard about this missing plane for some time and have a question regarding TCAS, if TCAS was left on it could aid the hijackers in ya know not hitting other planes, but if other planes were in its path wouldn't those planes TCAS log that a MH370 is in proximity or would it just log as an unknown plane? just wondering cos if thats a possibility then it could be used to get a good idea of where the plane was heading and possibly where it is. i fly on fsx occasionly not on a regular basis but occasionally i have little knowledge regarding TCAS but if any off you guys have any info on this subject i would be happy to hear.

    With regard to transponders of the 'Mode S' type (i.e. all transponders on airline craft):

    Each air frame is assign a 24 bit ICAO code that stays with the frame for the life of the craft. Every Mode S and ADS-B packet includes this code which uniquely identifies to (purported) originating frame. On the ground databases may be used to map this ICAO code to a current civil registration. This code is set into the transponder during manufacture or certain maintenance procedures. It is not accessible to the flight crew.

    In certain Mode S and ADS-B packets their is a 'Aircraft ID' field. This can be set by the flight crew. The value of this field is usually set to the flight code (e.g. MS318) or the civil registration otherwise. If this is changed in flight it might cause some real time confusion but cannot cause problems for any post event analysis which will go back to the ICAO code.

    TCAS uses that same air to air data link (i.e. that same transmitter) as Mode S and ADS-B. Turning off this data link turns off these three systems. Presumably this is what happened.

    Transmitting data over distances and in bad covered areas is really a challenge so it's not an option. Apart from this the black box is often in very bad shape after the crash and days or weeks of job could be needed to recover the information from the boxes. That is why instead there is a emergency transmitter onboard that is dedicated to just send an emergency ping in case of a crash, to help find the aircraft. I think this emergency transmitter normally activates on energy above 5G and it looks like it has not been activated so there are 2 options in this case.

    1) soft landing below 5G
    2) too hard landing so the transmitter was destroyed

    BTW I think it's possible for the pilot to switch the black box off, so we will see if there is any data to recover once the black box has been found.

    What are the possibilities that the aircraft made a ordinary landing somewhere, and is now un-remarkably parked on an airfield somewhere (possibly showing a different registration) or under a camouflage net.

    Clue of Mistery on the Ground of KLIA

    Hi guys,

    After more than one week of missing MH370 now there is conclusion that MH370 possibly not crashed and its act of somehow piracy or terrorism, it not crashed on land...if it crashed on land somewhere somebody must knew it, plane was flying till 08:11 AM UTC.

    Malaysian authority and media reports now concentrating on passengers and crew since Malaysian prime minister told in his press conference that now our focus is on passengers manifest and crew.

    What are you thinking on it?

    As per my opinion... on basis of logic that as per radar records transponder and other communication equipments were shut down separately…then the way plane took turn and maneuvering its path is work of experienced pilot etc.
    Now am on conclusion that agreed with all these outcome of inquiries…do you believe that this is single person’s handiwork?
    On passenger manifest more than 25 percent passenger age is 60+, the two passenger of stolen passport are cleared by Interpol, many are women with their life partners, many are artists, as per friend of pilot says he is good person. So who did this?

    Possible and logic answer is….

    In Boeing 777 as per Malaysia Airline, they accommodate total 282 passengers as per its seat capacity, with Business class 35 and in Economy class 247 passengers (See Attachment)

    As per manifest there are 227 passengers on board and 12 crew. Means 55 seats were empty.

    Who knows it was really empty?

    May be there was some persons inside before plane arrive at its gate for passengers, may be ground staff facilitate these peoples other than passengers. They didn't even pass through routine security or immigration checking or anything,they can easily bring weapons also.

    Otherwise to keep quiet 227 passengers + 12 crew by single person (pilot or co pilot as they suspecting) is impossible, and this matter is now not only for few hours, it’s more than a week now. this is well planned with multiple peoples involvement.

    So as per my opinion if plane is not crashed then they still can get passengers safely if they will investigate ground staff of Malaysia Airline or KLIA, surely they will find clue from KLIA ground only.

    Please share your opinion also…Thanks.

    Is it possible that the airplane has somehow been fueled up with more fuel than expected/planned before take off and therefor may have a greater range of reach then assumed?

    According to the latest news reports, the Malaysian authorities are claiming that the plane had NO extra fuel. That claim is dubious because carrying extra fuel is mandatory, so the plane has enough fuel in case of unexpected headwinds, a need to divert to a different airport or any situation that requires the aircraft to remain aloft for longer than normal or burn fuel faster than normal.

    The flight crew, FBO and airline would all be aware of how much fuel is on board. If one of the pilots ordered more fuel for some sort of suicide flight, then the FBO and airline would notice the unusual expense, and raise an alarm. So it's not likely that it would go unnoticed at this late date. Same thing if a hijacker bribed the FBO to load more fuel than ordered. Too many checks and balances. Too many bean counters watching their purse strings to allow it to go unnoticed.

    A plane's range is dependent on the amount of fuel loaded onto it. So while a 777-200ER has nearly 50% more potential range than a regular 777-200, the only way to realize that potential is to take off with full tanks. It's doubtful that the plane had more fuel than necessary to get to Beijing, plus the hour or so of mandatory extra fuel.

    Because of the cost of petroleum, planes like the 777 are designed to operate as efficiently as possible by default. There's not much that can be done to extend its range by a significant amount. It's possible that a hijacker-pilot attempted to save fuel by flying higher than the plane's certified service ceiling, which could explain the data suggesting that it was spotted at 45,000 feet. OTOH the lack of primary RADAR returns suggest that the plane may have been flown at low altitudes, which would have increased fuel consumption, and decreased range. Anything is possible at this point.

    If it is possible to seemingly disappear off the face of the earth with something the size of a 777-200 with full compliment of crew and passengers, with no trace, then I wouldn't discount anything. 'Checks and balances' should have meant the plane landed in Beijing last week as planned....but it didn't?
