Malaysia Airliner Communications Shut Down Separately: US Officials Say
Yahoo News ^ | 13 Mar 2014 | MARTHA RADDATZ, DAVID KERLEY and JOSH MARGOLIN

Posted on 03/13/2014 5:02:50 PM PDT by mandaladon

Two U.S. officials tell ABC News the U.S. believes that the shutdown of two communication systems happened separately on Malaysia Airlines Flight 370.

One source said this indicates the plane did not come out of the sky because of a catastrophic failure.

The data reporting system, they believe, was shut down at 1:07 a.m. The transponder -- which transmits location and altitude -- shut down at 1:21 a.m.

This indicates it may well have been a deliberate act, ABC News aviation consultant John Nance said.

U.S. investigators told ABC News that the two modes of communication were "systematically shut down." That means the U.S. team "is convinced that there was manual intervention," a source said, which means it was likely not an accident or catastrophic malfunction that took the plane out of the sky.

U.S. officials said earlier that they have an "indication" the missing Malaysia Airlines jetliner may have crashed in the Indian Ocean and is moving the USS Kidd to the area to begin searching.

It's not clear what the indication was, but senior administration officials told ABC News the missing Malaysian flight continued to "ping" a satellite on an hourly basis after it lost contact with radar. The Boeing 777 jetliners are equipped with what is called the Airplane Health Management system in which they ping a satellite every hour. The number of pings would indicate how long the plane stayed aloft.

It's not clear, however, whether the satellite pings also indicate the plane's location.

The new information has greatly expanded the potential search area into the Indian Ocean.

We are all playing a guessing game, so who knows?

IF this is a high jacking, it could be for either of two reasons.

The plane could be repainted to appear to be a trusted flag carrier and loaded with something destructive, or there was someone on board that the Malaysian government wanted to dispose of without causing an international incident.

So the plane disappears.

Or kidnapping for ransom.

The behaviour of the Malaysian government causes me to lean more toward political intrigue.

I was pointing to your statement that runway length is influenced by passenger comfort. It is not.

If a plane load of passengers has to land on a short runway the breaking and engine noise is uncomfortable for them.
Ask any Freeper who flew into St Thomas on American Airlines jets before they lengthened the runway. If you had a book on the seat next to you it would come sliding off and hit the seat ahead ,you would get jammed forward against your seatbelt. . St Thomas definaely needed a longer runway.- Tom

On April 27, 1976, American Airlines Flight 625 ran off the end of the runway, killing 37 of the 88 on board the aircraft. Following the crash, American Airlines suspended jet service, to the airport, using propliners until the runway was rebuilt to its present length.

Transponders return a signal from a radar ping. Even without the transponder returning a signal the radar signal is still returned. The airplane would still be tracked, but the altitude information the transponder returns simply wouldn’t be available,

“Look, there is no way the transponders would have quit 15 mins apart because ... “

The most current theory lining up all the holes in the Swiss cheese is 1) a loss of cabin pressure (possibly a rupture involving the area of the ‘E and E galley’ taking out the transponders) 2) due to a ruptured O2 bottle (like happened before on another A/C type.)

Oh yeah, we’ve been there before (in 2005) where the crew was done in by hypoxia:

Re
WE don’t know who was in command of this flight, but we do know that he knows how to fly a 777 so it is not likely that he ran out of fuel over the ocean. No nutcase gun slinger would even know how to turn off two transponders, much less manage the fuel systems, etc., for 5 hours. One of the crew was involved and the Malaysian government or someone within the government was/is involved. Again, who were the Chinese on board?~old curmudgeon

Reports have revealed...

” Transponders return a signal from a radar ping. “

Transponders return one of several ‘things’ depending on what was *received*’ from the ‘interrogator’ at 1030 MHz (in a “SSR” or Secondary Surveillance radar vs a “PSR” or Primary Surveillance RADAR/’skin paint’ system RADAR system using frequencies in S-band).

Transponder Modes A, C or “S” each have different pulse or interrogation characteristics.

And - anybody here familiar with ADS-B (Automatic Dependent Surveillance - Broadcast) technology?

What used to be called “ATCRBS” (At Crabs) back in the day:

On April 27, 1976, American Airlines Flight 625 ran off the end of the runway, killing 37 of the 88 on board the aircraft. Following the crash, American Airlines suspended jet service, to the airport, using propliners until the runway was rebuilt to its present length. Yes, I would say that those passengers were not comfortable. But this not not what determines runway length. Below is just a small part of what determines runway length. Temperature, altitude and wind may make a runway unusable on one day and usable the next. Note that the rule says no pilot will take off unless the aircraft can ....ect. It does not say what "can"is. That is determined by the aircraft manual. An aircraft can use one runway today that is not the longest on that airport because he is light and can meet the accelerate/stop distances. On the next day, the load on board, the temperature and the wind may require him to use the longer runway. Passenger comfort has nothing to do with it. §121.189 Airplanes: Turbine engine powered: Takeoff limitations. (a) No person operating a turbine engine powered airplane may take off that airplane at a weight greater than that listed in the Airplane Flight Manual for the elevation of the airport and for the ambient temperature existing at takeoff. (b) No person operating a turbine engine powered airplane certificated after August 26, 1957, but before August 30, 1959 (SR422, 422A), may take off that airplane at a weight greater than that listed in the Airplane Flight Manual for the minimum distances required for takeoff. In the case of an airplane certificated after September 30, 1958 (SR422A, 422B), the takeoff distance may include a clearway distance but the clearway distance included may not be greater than 1⁄2 of the takeoff run. (c) No person operating a turbine engine powered airplane certificated after August 29, 1959 (SR422B), may take off that airplane at a weight greater than that listed in the Airplane Flight Manual at which compliance with the following may be shown: (1) The accelerate-stop distance must not exceed the length of the runway plus the length of any stopway. (2) The takeoff distance must not exceed the length of the runway plus the length of any clearway except that the length of any clearway included must not be greater than one-half the length of the runway. (3) The takeoff run must not be greater than the length of the runway. (d) No person operating a turbine engine powered airplane may take off that airplane at a weight greater than that listed in the Airplane Flight Manual— (1) In the case of an airplane certificated after August 26, 1957, but before October 1, 1958 (SR422), that allows a takeoff path that clears all obstacles either by at least (35+0.01D) feet vertically (D is the distance along the intended flight path from the end of the runway in feet), or by at least 200 feet horizontally within the airport boundaries and by at least 300 feet horizontally after passing the boundaries; or (2) In the case of an airplane certificated after September 30, 1958 (SR 422A, 422B), that allows a net takeoff flight path that clears all obstacles either by a height of at least 35 feet vertically, or by at least 200 feet horizontally within the airport boundaries and by at least 300 feet horizontally after passing the boundaries. (e) In determining maximum weights, minimum distances, and flight paths under paragraphs (a) through (d) of this section, correction must be made for the runway to be used, the elevation of the airport, the effective runway gradient, the ambient temperature and wind component at the time of takeoff, and, if operating limitations exist for the minimum distances required for takeoff from wet runways, the runway surface condition (dry or wet). Wet runway distances associated with grooved or porous friction course runways, if provided in the Airplane Flight Manual, may be used only for runways that are grooved or treated with a porous friction course (PFC) overlay, and that the operator determines are designed, constructed, and maintained in a manner acceptable to the Administrator. (f) For the purposes of this section, it is assumed that the airplane is not banked before reaching a height of 50 feet, as shown by the takeoff path or net takeoff flight path data (as appropriate) in the Airplane Flight Manual, and thereafter that the maximum bank is not more than 15 degrees. (g) For the purposes of this section the terms, takeoff distance, takeoff run, net takeoff flight path and takeoff path have the same meanings as set forth in the rules under which the airplane was certificated.

Crew was out ... hypoxia ... see details here:

http://en.wikipedia.org/wiki/Helios_Airways_Flight_522

Helios Airways Flight 522 was a scheduled Helios Airways passenger flight that crashed into a mountain on 14 August 2005 at 12:04 pm EEST, north of Marathon and Varnavas, Greece, whilst flying from Larnaca, Cyprus to Athens, Greece.

A lack of oxygen incapacitated the crew, leading to the aircraft’s eventual crash after running out of fuel.

Takes about 30 seconds w/o oxygen and your reactions are crap at 30,000 feet ... and since your O2 bottle JUST ruptured your hull the ship (and you) are toast (RIP crew and pax).

I would agree but why did it change course ? Auto pilot would stay on programmed course. Many things do jot add up.

“With our global spy satellite system, there is no way we do not know where this plane went, where it is, and even what was said in radio transmissions.”

That’s a crock of hopium right there. Some passengers’ phones were on until Monday which means the NSA could easily tap into them and find out exactly where the aircraft went since GPS is standard in cellphones these days.

They could turn on their cameras and mics to see what they could learn, too.

“There has not been one piece of reliable information about this plane in over six days—except that it did not reach its destination.”

If the cell phones stayed on until Monday the aircraft did land somewhere.

“My first theory was that they had flown the jet to the Philippines, but it seems they didn’t have enough fuel for that so obviously that was out.”

How do you know how much fuel was put on board that aircraft. For all we know the fuelers of the aircraft were Muzzies, were in on this op, and loaded max fuel which means they could fly up to 9,400 nautical miles depending on the 777 model it is.

How did they turn off the transponders 20 minutes apart if they were unconscious?

In 20 minutes they would have been dead.

And I got lost on the time line.

How long between the last transmission and the sharp turn to the left?

The auto pilot would have been set up for the route long before they reached 35,000...probably even at the point they set up cruise/climb configuration.

So if the crew was incapacitated, the aircraft would have proceeded to Beijing on its own.

It might have exhausted the fuel before reaching Beijing, depending on how the fuel system on a 777 is designed, but would have tried.

Besides that, the captain can always call for more fuel load if he feels there is any need for more.

It would be easy to come up with a reason for more.

That 777 is going to more than likely make a surprise appearance in America. Remember Flight 92 that was going to take out the White House? That’s unfinished biz for the Muzzies. They could also take out NYC.

Time to put up a target list of cities and possible dates when it will show up.
