Hi again,

Thanks Alan, it seems to work but gives me an envelope shaped like a cross?

Hi all sorry no aircraft file attached but the attach selection box will not show on my browser, either IE10 or Firefox.

The Skyranger envelope needs to be as follows:-

0.21,258.0, 0.21,450.0, 0.36,450.0, 0.36,258.0
Ensure that the commas and spaces are as above. And you use your aircraft figures i.e empty weight may not be 258.0Kg
Lever arms Fuel -0.29 Pilot and passenger 0.15, baggage 0.15 Fuel -0.29

Rick,

I will try and up-load my aircraft profile for the Swift in the Aircraft profile forum section.

Hi Alan

Perhaps the basic empty weight and CoG is wrong even though the envelope is right?

I'm stumped as to why I can't get my W&B working on my Sky Demon/iPad. I've transfered all the info over from a working excel spreadsheet configured correctly for my AA5B, including loading points and loading envelope. The loading envelope is there within SkyDemon, and looks right. But no loading position appears, and I get an 'overloaded/outside envelop errot message. Any ideas as to what I might be doing wrong?

Tim and all

Tim,

Panic is over empty weight was at wrong arm. Should be 258Kg at 0,37 from datum.

With this the W&B works fine.

I will tidy all figures then save to cloud.

Thanks

Alan

Tim,

Thanks for quick reply, screen print is not working for me but, the Print Centre W&B page gives the loaded arm as 0.03 Moment 11 it seems as if the base data from the BMAA HADS HM04 sheet is out? If you cannot fix it I will mail Flylight for more information.
