Enemies Without Ace's Aptitudes

By Immortal, in Dark Heresy Rules Questions

I was just wondering doesn't it make more sense for the Ace to have the Field craft aptitude rather than the Willpower aptitude?

Does anybody believe this may be a print error?

Willpower makes sense. They're ballsy types, I suppose.

However, Fieldcraft is needed for Operate!

I really hope its a mistake. They really should have fieldcraft instead of finesse. The fact that the pilot role doesn't come with both aptitudes for operate seems really strange. It would be like not giving sages the knowledge aptitude. It hurts the whole point of the role.
