Hi,
sympathy for the crew involved, hope all works out for them.
How about some form of head up display that shows the actual runway ahead, even whilst in LVO conditions. As soon as the aircraft starts its acceleration it shows the approx point of rotation. Could be shaded to accentuate that area. Some form of dynamic principle that varies with wind speed etc.
The company i worked for previously had the weight the aircraft thought it was displayed in the FMC. The V speeds were also displayed, based on that weight. Most of the time it was over the loadsheet weight produced !.
Rgds.
