Couldn't agree more with Second Grace. On the 737 'classic' I think DES is far more useful. On a non-precision approach the FPA/
VB line was the crux of how I flew the entire approach. It makes them a doddle. It also tells you when the FMC thinks you should be starting to slow up on the intermediate approach, by displaying '210/FLAPS' on the Speed Restriction line. We also had an SOP of Prog page 3 on the PF side and APP Ref on the PNF side. I just used to brief the LHS instead how I wanted it set up.
On the 747-400 the DES page is less useful in terms of info, no FPA/
VB line. But there again we will soon be certified to do RNP approaches in it anyway so no need!
