QUOTE(atreyuangel @ Mar 17 2014, 08:24 PM) Like I have posted before, civilian radar signature reading (in this case 777) falls to DCA UFO, like their name is "unidentified"! Macam2 ada kat PULPAK tu bro  by request mesti ada dah 9M-MRx at their disposal! Did they call the DCA to identify the aircraft? Did they even challenge the plane? An aircraft without a transponder could be flying blind or having severe malfunctions. Was that even taken into account? |

QUOTE(atreyuangel @ Mar 17 2014, 08:29 PM) sorry bro, I can't answer that for you  but seriously the DCA/ATM SOP should be review and changed I feel that they owe it to the families of the victims to answer this properly. If the plane was detected there and then, it could be a difference between life and death. |

QUOTE(KYPMbangi @ Mar 17 2014, 08:51 PM) No, it should be the DCA calls the RMAF to identify the plane or track it where it was last seen on ATC radar But in this case the ATC assume first the plane had crashed, and then the SAR was activated without considering the probability of hijack or takeover For the million dollar question, military radar don't monitor commercial aircraft, and the blip they see in the radar is no different from any other commercial flight flying on that time That's DCA's job as they have both approved route and flight plan Thats why, DCA and military must link their data (route, flight plan and transponder data) in the future and better co-operation also But this also would take a huge undertaking as new infrastructure (both mobile and static radar) to be done, and a centralized air defence command (NORAD equivalent) would certainly be built I mean, doesn't the military track unidentified aircraft? After 9/11, even commercial aircrafts can become a weapon of mass destruction. The military uses IFF right? If there is a plane that doesn't have a transponder, and doesn't display IFF, isn't that a cause of concern? |

QUOTE(KYPMbangi @ Mar 17 2014, 09:32 PM) All modern commercial aircraft is equipped with IFF (Mode III) That's how our military radar sees it, but it doesnt tell you anything more than that (other than it's a commercial flight) After 9/11 the most proactive approach they have done is to embed an air marshall on american flights, Thats probably more effective than having more radar to watch the planes I thought IFF is turned off when transponders are turned off right? |

QUOTE(KYPMbangi @ Mar 17 2014, 10:13 PM) True, you can turn off the transponder from transmitting anything but IFF system works by replying the radar return (interrogation) Transponder data is transmitted IFF data is not transmitted, instead it's interrogated by radar system However, in this case transponder is inactive and IFF fails to respond right? |

QUOTE(KYPMbangi @ Mar 17 2014, 10:20 PM) The military radar positively identified the commercial plane, so I guess the IFF still works According to some posters, the military radar had ATR databases (probably a database of how a reflected radar signal can be translated to aircraft size/shape) that can positively identify the type of aircraft. |
