For the Coast aero database (Step 5) you set the nozzle exit diameter to
zero. (Power-Off.)
A question about nozzle diameter…
Hypothetically assume a nozzle attitude correction of +1000 lbf. If the motor
outputs 0.001 lbf measured on the test stand at msl, is the total thrust really
1000.001 lbf?
This effect leads to a strange jump discontinuity at the end of boost.
(Possibly related to the site altitude bug)
Is there ever a case where site altitude 0 yields a higher max altitude than
site altitude 1000? (assume everything else is equal)
