If (more likely) it continued at least 30 min. on the original heading before turning, in order to stay clear of Indonesia, it would only get as far as latitude 36 by the last ping, latitude 40 if it stayed airborne for another 30 minutes after that.
Interesting, Hamster... Has anyone here determined a reasonably accurate range/endurance given we know:


49.1 metric tons of fuel, TOW 223.5 tons, air temp & meteo/wind, rate of climb, cruise speed (to loss of comms), & we have an idea of flight path (radar) & descent to 5000ft AMSL from LKP to LEP.


From that info some here must be able to ascertain a reasonably accurate estimated max range based on a couple of scenarios:


A> 2nd climb back to FL350, cruise until flame out + glide
B> no 2nd climb, continue at 5000ft until flame out + glide
C> assume no descent from IGARI & FL350 maintained until flame out + glide


Any navigators here with the appropriate knowledge & skills willing to post some calcs/estimates???


Might prove helpful for the crowd ;-)
