First of all, THANKS to all you from Concorde family for this fantastic topic. Started reading last night and almost slept in front of computer trying to read everything!
As a Concorde fan for 10 years (since I bought FS2000), and passionate developer of SSTSIM Concorde and FSLabs ConcordeX (flight dynamics, weight and balance), it's simply awesome to have you guys and gal here sharing your memories.
Regarding the CG corridor, here's a fantastic graphic from online Concordepedia, aka ConcordeSST.com, Technical/Fuel System section:
Interestingly, it doesn't show a warning for CG>59.1% above M1.6, opposite to what M2Dude said earlier on the topic.
I got curious on the Max Climb/Cruise and ALT ACQ not being primed. How the levelling at FL600 was done? Manually?
Regarding the fuel tanks, specially tanks 6 and 8: did these tanks' lateral center of gravity change with quantity? Due to their completely assymetrical shape, I'd expect some change in it.
Operationial question: did BA use the 380kts descent profile? Have heard that only AFR used it, but Haynes' book says that BA started using it too.
There are many doubts regarding procedures as manuals and informations available on the internet are mostly from BA 1976 entry-into-service era. But i understand many things changed along the years, as I can see on a Aug 2000 manual I've got, with percentages showing differences from the 76 era, or even completely new tables.
Well, that's it, hope to be able to contribute on the topic, but mainly learn from you that flew the real thing.
