Unnecessary. Any dummies will get the same g forces as the rest of

Do the seats/couches provide any G force reduction? Or are they "fixed"
and protect the occupants by being perfectly moulded like on Soyuz?


No. Seats can reduce 'jolt', but until we get antigravity no seat can
reduce g forces.


If there is some suspension provided by the seats to cushion landing,
you will want to have human-like mass on the seats with G force sensors.


Why? If the capsule doesn't exceed 3.5g, stuff in the capsule won't
exceed 3.5g, either.


Things that don't matter just don't matter. That doesn't matter.

Ensuring that the capsule re-enters correctly when the mass it carries
is that of a crew would be important.


The unnecessary testing you suggest will take forever, since you would
need to 'test' with from zero to seven passengers each weighing from
105 to 200 pounds, plus varying return cargo from zero to maximum
capacity.


A different mass means different F
forces during re-entry interface and during the actual landing.


Not enough different to matter. You act as if nothing is known and we
just build the things and shoot them up there on a wing and a prayer.
Not at all how it works.


And it would presumably also test the software when firing thrusters to
ensure it can handle the mass of the crew.


You seem under the delusion that the crew will mass MORE than a cargo
variant will carry.


CG would still presumably be different. You seem to be trying to make
the argument that the only way to man rate a system is to fly people
on it,

I said dummies, not people.


They're not going to send you, Mayfly.
