Vref disappear

Featured Replies

I use PMDG737NGX to do touch and go, but the Vref and the runway in ND disappear when the plane touch the ground.who can tell me why,thanks a lot!

Well, obviously, you have just landed... why would you need the FMC for pattern work anyway?

I have done many touch and go landings and Vref disappears somewhere while I'm doing on-ground stuff, and appears again after flap retraction.

I'm setting only performance data via FMC and let it calculate Vref.
