QANTAS have their FMC's pinned at 1.3g.
You fly attitude in severe turbulance. (airspeed tape usually impossible to read in severe turbulance anyway)
I have never met a QANTAS pilot not aware of the temp drop crossing a jetstream and the implications entering from the cold to warm side we are always crossing them at close to 90 deg. due route structure. (have yet to find a way of 100% compliance of seat belt sign!)
