Hello fellow helicopter pilots. I know this is a little bit off topic, but... I'm developing a hardware VEMD for training, based on a flight model in X-Plane. I have T4, TQ and Ng, somehow I need to magically convert these to a FLI value. Now I somehow need to figure out what Thales does in their black box, at least a little bit. Does someone have a rough idea on how these figures form the FLI value?
Ng for example, at 83.6% with a max of 98%, does not necessarily mean you're at 8.5 (83.6 / 98 * 10) FLI value. So it is that at some point the Ng starts to become critical, that might be at for example 96 or 97%...who knows...
I would guess that in general you're torque limited, but for example 22.5% torque can correspond to a FLI value of 3, judging from this video:
I know it's a bunch of magic, and I'm afraid that no one knows, I just wanted to give it a try, maybe I'm lucky....
