At the beginning of Time Squad, Jenna tells Blake that he has correctly followed her directions for flying Liberator manually. He then says "let's ask the expert" and asks Zen if he performed the maneuver correctly. Later on, instead of asking the pilot's opinion of the controls in the capsule, he asks Avon, when there isn't a reason in the world why a systems analyst and avocational hacker would know anything about them.
But this may have more to do with distrust of his staff than distrust of Jenna's abilities as an individual or as a woman--after all, Blake has Vila and picnic cooler go to the communications station, but Blake seems quite surprised when Vila is able to open the door to the core unit.
