From 1.6.4 of the report;
"The retraction of Group 'A' LE flaps is shown as a color change on the flap indicator EICAS display which is hardly visible on the display."
I don't see what difference it would have made if they had known about the LE flaps, as it occured after V1, and there was no way of extending Group 'A' except automatically when airborne.
Was it rather irresponsible of the SACAA to commend the crew without having consulted the experts on PPRuNe to see how it could have been done better?
