Pmdg 737ngx tutorial

[SailorDoc 1]

Needing some help. I'm trying to work my way through the 737ngx tutorial. Running FSX and FSUIPC. I think I have everything up and running correctly, though being new to all this, maybe not. Anyway while heading down the runway almost at rotation speed, suddenly the speed brake kicks in and everything starts to slow down quickly. Don't understand why this is occurring. Will someone help me out? Thanks

sounds like  you got conflicting  keys    for your speed brake,  check you key assigments in  your settings

Full names in the PMDG forum please.  See forum rules in pinned topic.

 

Could also be noise from brakes if you are using pedals or movement from the throttle if you do not have the best throttle override settings for you. See Introduction manual PMDG Options settings for throttle.  I use override in HOLD only.
