Report: Plane Dropped To 5000 Feet To Avoid Radar
The New Straits Times says Flight 370 dropped to 5000 feed to avoid radar detection.
In an exclusive story, the government-backed paper said investigators analysing MH370’s flight data revealed that the 200-tonne, fully laden twinjet descended 1,500m or even lower to evade commercial (secondary) radar coverage after it turned back from its flight path en route to Beijing…
Investigators poring over MH370’s flight data had said the plane had flown low and used “terrain masking” as it flew over the Bay of Bengal and headed north towards land, the NST reported.
Officials, who formed the technical team, were looking into the possibility that whoever was piloting the jet at that time had taken advantage of the busy airways over the Bay of Bengal and stuck to a commercial route to avoid raising the suspicion of those manning primary (military) radars, the paper said.
“The person who had control over the aircraft has a solid knowledge of avionics and navigation and left a clean track. It passed low over Kelantan, that was true,” the NST quoted an anonymous official as saying.
“Terrain masking” refers to an ability to position an aircraft so there is natural earth hiding it from the radio waves sent from the radar system. It is a technique mostly used in aerial combat where military pilots would fly at extremely low elevations upon normally hilly or mountainous terrain to “mask” their approach.
