Jump to postThanks for that JetMech, apologies for the late reply. Other than the moving of the Stab trim automatically I order to avoid any Mach tuck issues I still cannot understand how moving the elevator to a more nose down position enables more up stab trim!!

Hoping someone clever out there can clarify this for me. Came across this whilst trying to brush up on 737 tech knowledge. What I can't get is that. How does putting the elevator in a more nose down position enable you to move stab trim to a more nose up. The limits of stab trim movement don't chang...

Jump to postOn the inflight landing calculations for the 737-800 for a Dry runway with Auto brake 3, there is no corrections to apply for the slope of the runway.

With regards to wind speed given by ATC/atis when they say for example “160@16 knots, varying between 180 and 120 degrees”.
