Aviophobia, aviatophobia – fear of flying
Fear of flying is a fear of being on an airplane (aeroplane), or other flying vehicle, such as a helicopter, while in flight. It is also sometimes referred to as aerophobia, aviatophobia, or aviophobia.
Fear of flying may be a distinct phobia in itself, or it may be an indirect combination of one or more other phobias related to flying, such as claustrophobia (a fear of enclosed spaces) or acrophobia (a fear of heights). It may have other causes as well, such as agoraphobia (especially the type that has to do with having a panic attack in a place they can’t escape from). It is a symptom rather than a disease, and different causes may bring it about in different individuals.
