744 drag curve Q.
Hi, have a Thrust Req. graph for the -400 and am trying to interpret it. Here is the info...
31000-33000 ft
STD day
THR Req lb vs MACH
Curves represent typical drag curves but are numbered 1.9, 2.2 2, 2.5, 2.7, 2.9, 3.1.
Formula on the graph says
................6
W/delta-10 LB
--------------------
.........1.9
2.2 thru 3.1
Dots added to put everything in the right spot (space bar wont do it) That is 10 to the power of six I am trying to do.
delta is the lower case greek one. How do I get a sensible answer out of that all in relation to weight? Trying to relate Min Drag speeds and LRC speeds to what comes out of the FMC.
All help greatly appreciated.
