rbp Posted April 24, 2023 Report Share Posted April 24, 2023 After having my panel redone, my BEW went from 2392.74 to 2312, a net gain of 70.74 UL, or almost 12 gallons of fuel. The CG went from 44.22" to 44.83, which is negligible. New W&B: BEW 2312 UL: 1056 leaving 522#s of pax + cargo with full fuel fuel 1 Quote Link to comment Share on other sites More sharing options...
LANCECASPER Posted April 24, 2023 Report Share Posted April 24, 2023 The Bravo I sold in November 2021 had long range tanks and after some panel work we got the useful load (on paper) to 1032. Mine was a 1993 and had the lighter Royalite interior panels. I had the paperwork that said 1032, but I am convinced that had it been set on scales and re-weighed the number would have been "different". Re-weighing is really the only way to know for sure, but is usually disappointing. Quote Link to comment Share on other sites More sharing options...

I’ll compare notes some time in June. Currently I’m at 2375.69# and 45.62”, UL 993#. Cheers, Rick Quote Link to comment Share on other sites More sharing options...

PilotX Posted April 25, 2023 Report Share Posted April 25, 2023 I currently have UL - 1053. I have LR tanks so 118 gallons leaves me with 345 for pax and pudding. Quote Link to comment Share on other sites More sharing options...

Pretty close for a parallel valve O360 which is ~40lbs lighter. Quote Link to comment Share on other sites More sharing options...

All the support equipment...dual batteries & alternators, dual vacuum pumps, more hoses, intercooler, oxygen system, more engine instrumentation, bigger fuel tanks, heavier propeller, heavier cowl, more avionics, with remote boxes in the tail and associated wiring, heavier tires, extra upholstery, extra insulation for high altitude ops, and other soundproofing ...there are lots of details that add the weight.

My E had nothing but 2 nav-coms and a Brittain in it and it was just shy of 1750. Your J must be really light. Quote Link to comment Share on other sites More sharing options...

Your J must be really light. Betting you had WX10 (10 lbs), kns 80(6 lbs), vacuum system with backup (20 lbs), etc….just like rbp I lost 70 lbs with panel upgrades.

That’s a chubby E model. That’s 70lbs heavier than my F model which has a pretty basic IFR Panel and is fully insulated. Quote Link to comment Share on other sites More sharing options...
