Hard Landing?

Note quite. It shows “delta G”, i.e. difference between gravity and the G load on the aircraft at touchdown, which is determined in a slightly complicated manner. It’s used to determine when an inspection of the landing gear is required. But we know how simmers love to chase butters… :)

Thanks a lot! So what is the appropriate range of that value?

It doesn't really show that though. As an example, if you rotate the main gear into the ground a lot of the cabin G "feel" is coming from the wings right down to the point of contact, so the HLIS won't show a high value, even though it would feel nasty to the passengers.  In the opposite sense, holding off then "rolling it on" by reducing the pitch attitude slightly will read higher on the HLIS (as the gear is taking more of the load) but would feel better for the passengers.

In short - HLIS is a maintenance tool - not a landing rate / feel monitor.

Thanks for your explanation!! :)
