Thanks again, Colin:
I like the Embraer 120 very much, I fully recommend it to you, and it's working very well here with GSX. As with the Saab 340, there's the problem with the passenger heads at the top of the aircraft, difficult to be solved. Yes, the baggage handlers just put the baggages over the belt from the carts, and you can see them going up/down (loading/unloading) over the belt very nicely, and hear some noise too.
The logic I used for GSX with the SAAB and the Embraer is the same one that didn't work well with the ATRs (I have both the -42 and -72), so to me is still not clear why it worked in some cases and did not in others. Glad you were here to help.
Keep in touch.
Cheers, Ed
