Live CG and gross-weight preview on the Part 121/135 dispatch briefing
The trip-sheet briefing's weight & balance section now computes a live approximate gross weight, CG, weight margin, and envelope check from the pax/cargo weight already captured there — reusing the same pure engine and aircraft-profile data Part 91 flight planning uses. It's a planning aid, not a dispatch release: fuel weight is excluded, the load arm is approximated rather than per-station (aircraft profiles don't carry per-seat/cargo-hold station data), and the PIC and the dispatcher's own weight-and-balance process remain the final authority.
