Hey IFC!
I had an idea, what if IF had the co-pilot callouts;
“80, knots”
“V-1”
“Rotate”
“Positive rate”
“Gear up” (when gear is raised)
I realised RFS has it when I played it the other day. It would be so much more easier than going into simbrief and finding out, and Simbrief isn’t always reliable aswell. It is to my belief that these callouts are used to the pilot in control doesn’t have to take his eyes off the runway. The “80 kts” is used for both pilots to ensure their PFD speed indicators are working and in sync.
Here is a video of Boeing pilots displaying these callouts. Ignore the rest of the video, the rest is ATC communications etc.
Thanks for reading!
