Makes it a bit tough for us gumbies with our hands on the controls...
Not really. The discussion earlier with djpil provides a clue.
For the normal category aircraft, the limit load factor, typically, but not always, is 3.8g.
Vo is going to be near to 1.95 x Vs.
If you want to give yourself a bit for mum and the kids in turbulence or manoeuvring, perhaps aim for something closer to 1.6 x Vs.
The only caveat is that you need to apply the PEC to the Vs numbers so that the sums are in KCAS and then convert the answers back to KIAS via the PEC. Use the Vs values for whatever gross weight might be of interest and it all should work out fine and dandy.
