RE: UAL93 data for SANDIA

thanks, please give me the tabular data for the last 10 seconds. —Original Message From: Ritter James Sent: Monday, October 15, 2001 7:45 AM To: Eiiingstad Vern Subject: FW: UAL93 data for SANDIA

I asked for the last 10 sees but he's plotted 25 sees in this file. Original Message From: O'Callaghan John Sent: Friday, October 12, 2001 6:08 PM To: Ritter James Subject: UAL93 data for SANDIA

From the info provided by American for AA11: Zero Fuel Weight = 21 ] 446 Jbs Trip Fuel = 76400 Ibs Ramp Weight = 287846 Take Off Weight = 287126 (Ramp weight minus fuel used during taxi) The following numbers are approximate. Using fuel burn rates from the FDR data on another 767, and adjusted for AA11 gives: fuel used during climb = 7250 Ibs fuel used at 29000 ft = 4840 Ibs fuel used during descent = 1950 Ibs Which leaves a total weight at impact for AA11 of approximately 273,100 Ibs, of which there is approximately 61,640 Ibs of fuel. From the info provided by United for flight 175. Zero Fuel Weight = 212348 Ibs Take Off Gross Weight = 288348 Ibs Assumed 76000 Ibs fuel at takeoff The following numbers are approximate. Using fuel bum rates from the FDR data on another 767, and adjusted for UAL175 gives: fuel used during climb = 6380 Ibs fuel used at 31000 tt = 4900 Ibs fuel used during descent = 1850 Ibs Which leaves a total weight at impact for UA175 of approximately 275,220 Ibs, of which there is approximately 62,870 Ibs of fuel. The type of fuel for both airplanes was most likely JetA. If you need more information or have any questions please let me know.
