The other one that I think is useful from a simulation standpoint is "fuel
freeze".  The benefit is that in a training scenario, you can concentrate on
your training tasks without needing to add the complexity of fuel
management.  And for wind tunnel type testing, this would eliminate a
potential source of weight/balance change that could skew your data.

And it's also nice from a simulator testing or playing standpoint.  If you
want to do an around the world flight, or leave the airplane on autopilot
while you go sleep for a while, it's nice to know that you aren't going to
run out of fuel and be a lawn dart when you return to the computer.
