Check,
We might simply be getting into semantics here, but an observer on board a turning aircraft feels an increase in force on the normal axis which is exactley the same as an increase in weight. From his frame of reference, his and the aircrafts weight has increased.
Astronoughts in space are still subject to gravity, but as their orbital acceleration exactley cancels it out are said to be weightless. I would think it therefore not incorrect to say someone experiencing an increased force due to acceleration is more "weightful" i.e has experienced an increase in weight.
