Missed this one!
Naturally, Jim and Shawn are correct, along with EESDL.
You can produce your own charts if the FLM ones are not user friendly. The thing is to determine what fixed parameter you want (RoC, Weight etc). It takes a lot of time extracting the plotting points, but you can then produce a more user friendly result. e.g. for the EC-155 I produced a single graph to determine PC1/2 en-route weights from 4 separate graphs in the FLM; much easier to use!
It is also correct that many older types can hover OEI; just not necessarily at the weight you'd like them to!
