767-300F vs 767-200SF - range issue?

[Tha_Ape]

The 200SF is supposedly converted from both the 200 and 200ER. Still, it has a nominal range (@ max payload) of 'only' 2900 nm, while the 300F has a range between 3220 and 3300nm.
This is from mentoring, so I cannot check the payload/range graphs, but it still looks strange: while a 200SF based on a 200 would have a shorter range, one based on the 200ER should have a longer range than the 300F.
Or do they took off the additional tanks during the conversion?

Does anyone have the range graph for the freighter conversion from the 767-300ER please.

The payload / range graph of 762F looks very much like that of vanilla 762, rather than 762er.  It can't carry anything past 5500nm.

Maybe 762er has some extra tanks, and 762F uses the space for extra tanks for more cargo.  (just speculating).

The B767-200SF in AWS is based off the B767-200BDSF - 159kg MTOW (+7.3tn) variant. The conversion is done by 3rd party (IAI Bedek) and their STC only goes up to 159kg MTOW, even though there are higher MTOW variants of the 767-200ER (179kg MTOW).

Edit: So digging a bit deeper: The early build 767-200As could be converted into "-ERs" with MTOWs of around 159k. By making use of the dry center bay for fuel and uprating the engines it could have greater range/power then its original specs. However, a 767-200ER new build makes use of the center bay and other fuel improvements to have a greater fuel capacity over the 767-200A. So, I assume the BDSF conversion just brings a 767-200A to 159k MTOW ER specs.

Well, I guess there's a feature request waiting to be posted.
