BlueConcorde
...Haynes' book on page 23, says about an increased MLW of 130 tons instead of the famous 111,13 (sic) tons. I NEVER, ever, heard/read about this, can anyone shine a light on it?...
I'm not aware of what Haynes may say about Concorde - I don't have a copy of the book and haven't read it - however it is well documented that landings at weights up to 130,000 kgs were permitted on Concorde, provided various conditions were met.
It was a Conditional Procedure called Fuel Saving Landing.
BA did not plan flights to land at 130,000 kgs but the procedure was available for use when required.
In practice it was rarely used, and the occasions on which it was used tended to be following a return to the departure airfield, or a diversion in the early part of the flight, with the aircraft still above the (normal) maximum landing weight, in order to reduce the amount of fuel to be jettisoned.
