737 driftdown altitude - "Lt / Rt eng out"
FMC eng out cruise page has a slightly different driftdown altitude for Left or Right eng out.
The only info I can find on this is from Bill Bulfer:-
"This tells the FMC which engine has failed so it can account for the actual bleed configuration. Accuracy of the maximum altitude calculation is improved."
If someone could expand on this it would be much appreciated.
