A bubble canopy refers to the transparent, curved cockpit enclosure on an aircraft or vehicle. Synonyms for this term might include "dome canopy," "bubble hatch," "perspex dome," "panoramic windshield," or "acrylic canopy." Each of these phrases is indicative of the same basic feature: a clear, rounded, and often curved piece of material that allows the pilot or driver to have a panoramic view of their surroundings. These types of canopies are often associated with military aircraft or high-performance vehicles, and are valued for their ability to provide excellent visibility and situational awareness.
