737 NG Blended Wing
Fishing for answers! Factory fit and retrofit blended wing. Factory fit apparently has spar reinforcement. Retrofit does not. This implies factory blended wing is more efficient in that it generates more lift than retro version. Does performance data in QRH and FMC reflect only retro wing, or is it specific for individual retro/factory wing aircraft.
