PJ2;
I thought that in the Report pictures we are looking towards the trailing edge, i.e. wing on the left, flap on the right. (See pylon trailing edge at the far left of second picture). In the sea-bottom picture we are looking towards the leading edge, and I was searching at the forward end of the heavy track or beam, for the arm that is flush with the wing under surface in the first report picture (flap extended), and perpendicular to it in the retracted position shown in the second report picture. The drawing you show upsets my sense of orientation. Have I got it all wrong?
Regards,
