727-200Adv not allowed over 2800nm

[groundbum2]

I have a few routes in GW4 in the 2828nm range that I would like to be flown by a 727-200Adv +11.5ton model. The stated range is 2750, and I have a seat config that says I can do 2820. If I look at the range chart for the aircraft I can easily do 2828 or more.

But if I try and transfer the schedule to the 727 from a Britannia it fails "plane would have no payload", and 727 is not available in the drop down box if I edit the route.

Route is EGLL-OTBD, aircraft would be #5209, GW4, simonrulz airline.

Help!

According to the payload-range chart the payload of this aircraft on 2820nm route would be ~4875kg (approx 45 pax). Not sure yet why the fleet type does not show up in route editor dropdown...
