Following from FCOM
B737 NG FCOM
STS operates most frequently during takeoffs, climb and go-arounds. Conditions
for speed trim operation are listed below:
• Airspeed between 100 KIAS and
Mach 0.5
• 10 seconds after takeoff
• 5 seconds following release of
trim switches
• Autopilot not engaged
• Sensing of trim requirement
B737 -300 (non-EFIS) FCOM
Flaps not up
Air speed 100-300 KIAS
N1 above 60%
(Rest of the conditions same as NG above)
MAX unknown. (some one in this forum can help)
Only Tristar_Drvr has mentioned he is flying the MAX in this forum. So he should know.
