Surprise !

The Sims are being updated.
Whilst you are totally correct, I wonder how they are or have been updated. Did Boeing provided updated data to the TDMs for both MAX and NG?

My understanding on the NG is that the classic stab force model was effectively supplied as the data by Boeing and only the larger Canadian TDM elected to use different data derived internally (so someone then had doubts?)

Assuming this alternative means of compliance was within the FFS initial qualification documentation, the respective NRAs really should have picked this up on the NG.

However, if it wasn't then certain operators and that TDM maybe have some interesting questions coming their way!
