Under what condition may a commander recommend prohibiting the wear of the aviation badge?

The condition under which a commander may recommend prohibiting the wear of the aviation badge is primarily associated with a member being disqualified due to fear of flying. This is significant because the aviation badge is a symbol of qualification and capability in flying duties within the military. If a member has a fear of flying which prevents them from participating in flight operations, their qualification is compromised. This disqualification not only affects their ability to perform flying duties but also reflects on the standards required to maintain the aviation badge.

The other options, while they might lead to disqualification or inability to fulfill certain flying roles, do not specifically emphasize the psychological aspects that relate to a commander’s authority to recommend a prohibition on the aviation badge. Members who are unqualified or have not completed necessary training, while they may not be permitted to wear the badge, may still have an avenue to achieve the qualification later. Similarly, being on temporary leave does not inherently disqualify a member from wearing the badge since it is usually related to their status during active duty rather than their qualifications or capabilities.
