Not so fast.

Just as Vmc (red radial line, not the blue line) is a certification number and not a fixed value, so is blue line (best single engine rate of climb).

You may be confusing Vmc with Vyse.

Not all multi engine aircraft have a blue or red line.

Mr. Burke is correct red line not blue, typo error.... for all multi AC that have a published Vmc. Vmca (actual) will usually be lower.
