Which of the following is NOT a situation to call a KIO?

A situation where you would call a Knock It Off (KIO) is when a pilot has met or exceeded the learning objectives of a training exercise. In this context, the purpose of a KIO is to interrupt the training and allow for debriefing, particularly if the objectives have been satisfactorily met.

This allows instructors and students to discuss the points of learning gained during the exercise without the distraction of continuing a potentially unsafe or unproductive scenario. Therefore, experiencing a situation where learning objectives have been met does not necessitate a KIO, as it indicates a successful completion of that phase of training.

In contrast, the other situations — such as having flown past bingo fuel levels, losing situational awareness (SA), or experiencing a radio failure — indicate safety concerns or training disadvantages that require an immediate halt to the exercise for the safety of all involved.
