I fly into Jackson Hole routinely in an A319. On the A319/320, at my airline, the procedure and required callout by the PNF immediately after touchdown is, "Spoilers up" or "Spoilers not up". It's the same at Jackson Hole as it is anywhere with a long dry runway. Given the quality of my landings, that's usually the first indication we have touched down, not having felt anything.
Is the 757 similar? Does a display pop up showing the position of the flight controls at touchdown?
If spoilers did not deploy, the pilot must immediately use manual braking aggressively to assure stopping the airplane on the available remaining runway.
