The FMC on the 744 provides two sets of driftdown speeds and altitudes - one based on min drag and the other based on long range cruise (all based on 2 or 3 engines operating as the case may be). I always note the E/O Max Alt as it will not only tell me how far we need to drift down but also what the rate of deceleration is likely to be at the current weight and altitude.
