I have an aircraft profile for the above aircraft, but can I get the file attached... No. Just a box at the top of the screen with "add attachement" just showing at the bottom.
any ideas? I've tried Chrome / Firefox and IE all with no success.

Tried to post some photo's to do with my "Weight and balance Tutorial", but had exactly the same problem.

Ah ha. It finally allows me to upload the profile. Hope someone finds it useful.

Hi Chris,

Did find it useful and tweaked it a little bit. My envelop has different parameters, i will check those.
Other differences: we fly mogass @17l/h; best glide 1:14; there is a differnce in loading between seat in the most front or most back position. Therefore i have introduced a pilot and separate passenger loading  (with pilot seat most backwards).
I have to check all the parameters again to be sure i have a legal W&B on me.
