Yes they do. When doing the SOPs the CM2 calls the V speeds and the Green Dot speed from the MCDU. The CM1 confirms that it's within 2 kts of the computed Green Dot speed from the laptop. If it's not within 2 kts, something is wrong
Not trying to be picky here, but it's actually CM1 the one who calls the speeds from the MCDU, after having inserted them, and CM2 x-checks them with the numbers previously recorded on Master OFP...
This doesn't change the fact that we do have a gross error check and I think that if it's properly done the system is not that bad.
The TOW weight used in the LPC is first checked by CM1 against the INIT-B TOW and, eventually, the INIT-B TOW is compared with the one on the Load sheet by both pilots. How many more times must a weight be checked? Until the procedure becomes ridiculous?
I remember the last time the TO performance error check was changed that some guys were complaining that this was to much and we were not trying to go to the moon...
