Understood. I was picturing a scenario where they BOTH think they're right...who gets the aircraft at that point?
The instructor evaluator would take the aircraft as they are likely considered the PIC. I know my buddies in the Air Force will say rank doesnt mean anything, within reason, in regards to operating the aircraft. They have specific aircraft commander qualifications. They could have a full bird in the right seat new to the aircraft with a LT in the left seat as A/C commander. The LT is in charge during operations of the a/c. I think the Army has the same so a CWO, even though subordinate to a commissioned officer, could/would be the aircraft commander. In the case we are discussing im pretty sure the CWO was the aircraft commander as he was acting as an instructor/evaluator.
