You’ll find some info about C-130 speed in this topic:
I know most probably won’t know what this means… but take my word for it. 250 is what we “TRY” not to exceed. Do we exceed it, yes sometimes we do. Are there things or inspections that have to be done if we do, yes.
There is a MAX speed for the C130s. It may be well above 350-400knots. But there are so many other considerations in there that limit us to flying slow. Almost every C130 out there has printed flight control surfaces that limit them.
(/close) pls thx for your help all.
