Malaysian Airlines 777 not as far as the experts speculate it - TopicsExpress



          

Malaysian Airlines 777 not as far as the experts speculate it would be. The plane no way could it be flying for 6 more hours after it vanished from radar. Once the signal was lost the pilot or pilots dived for low altitude. Radar coverage gets worse the lower you go, so if you want to stay off primary radar, you will fly as low as possible. Theres a drawback to this strategy, however: The lower you fly, the slower you go, and the more fuel you burn. A 777 can go 485 knots burning 6000kg of fuel per hour at 35,000 feet; down at sea level, you’re talking more like 9000kg per hour and only going 310 knots. So if you can go 2,000 miles at altitude you will probably only go around 800 miles down low.
