Lift to drag ratio of airliners I don't know if this is the right place to ask, but I am looking for lift-to-drag ratios (L/D) of different airliners. I have found a paper [1] which has some estimates of L/D for some jetliners, but it's a limited sample 
Table 3. Estimated aerodynamic characteristics of jet airplanes (L1011, a few Boeing, Douglas and Airbus). This question also looks promising, but delivers airfoil numbers, not aircraft numbers, sadly. Is there any online resource or a place that might point me in the right direction?

In quotable literature, I recommend „Aerodynamic Design of Transport Aircraft“ by Obert. In other useful stuff, there is a very useable (but not proven by Boeing) aerodynamic model of a 787 available on the Piano X website.

I‘d add that for any really useful analysis other than level flight, getting hold of a decent engine model giving maximum and minimum (net) thrust as well as fuel flows throughout the operating range will, in my experience, prove much harder than the aerodynamics...
