I presume that limits STS to the climb.

Thanks for that, that is interesting, that engine parameter is not listed in the conditions for speed trim for the NG.
Conditions for speed trim operation are listed below:
• STS Mach gain is fully enabled between 100 KIAS and Mach 0.60 with a fadeout to zero by Mach 0.68
• 10 seconds after takeoff
• 5 seconds following release of trim switches
• Autopilot not engaged
• Sensing of trim requirement
