Do these abilities stack? Both the pilot ability and the crew card reference "when you reveal your dial" that suggests that they do not (Hera changes a 1-straight to 1-bank, the navigator changes the 1-bank to 3-bank). HOWEVER, this is the same as Boba Fett/navigator which the FAQ says it DOES stack.

So what sayith the experts?

Those do stack but you can only use them once per reveal. All of the "when you reveal" abilities have an opportunity to resolve when you reveal your dial. Hera could reveal a white turn, use Navigator to change to one of the red turns, and then use her ability to make it a K-Turn.

There was an email from Frank Brooks arpund here somewhere that confirmed that any changes made to your dial during the "when you reveal" window counts as being revealed with the most recent setting replacing the earlier ones.
