Derivatives 21 Part 1b
A natural question is to ask what happens if the airspeed is increased slightly. We know that more speed is more lift. We also know that more speed is more drag. For this reason it can be nice to get a pair of numbers to quantify this coupling.
The coefficient of lift and of drag (shown as 0.232 and 0.0106) will give us an approximate lift to drag ratio of 22.
As you may have read on this wiki page, there is an issue with the in-editor calculations not counting the greater drag of the open air intake. As a consequence the performance is not really indicative of cruise flight; it is more indicative of engine out gliding flight. For our purposes though, let us just pretend the data is accurate and use the inaccurate L/D estimate of 22.
