757/767 LNAV behaviour in conditional waypoints

Hello !

B757/767:

In the procedure below the FMC manual states that if 4000ft hasn't been reached at LAS280 then the plane will continue without turning.

What would happen in this case, if the altitude is not reached ? Will the FMC give up at some point and drop out of LNAV?

Also, will this behaviour be consistent for all the conditional waypoints ((INTC), Vor and DME intersects, etc...) ? Ie. will LNAV be dropped at some point and if so, when and what AFDS mode will take over (HDG HOLD?).



cheers
