if restricted to 250kts (way below min drag) you'd get pretty poor rates of climb - about 1000fpm if you were lucky
Wow, that's pretty bad. You'd figure with a T/W ratio of around 0.40 you'd do far better than most other aircraft.
With respect, that sounds more like the sort of climb rate associated with noise abatement rather than full power. Brian Calvert quotes 250 kts/2000ft/1000fpm/12deg attitude/reduced thrust for this. At 8000ft/400 kts/dry climb thrust he quotes 3000fpm, which is more the sort of number I would have expected (it is all a long time ago ......)
